Figure 2 Services Ready Small Branch Network Topology
Figure 3 shows the high-speed WAN interface cards (HWICs), voice interface cards (VICs), voice WAN interface cards (VWICs), and network modules configuration on a Cisco 3945 router. WAN connectivity is provided by the 4-port high-speed interface card (HWIC-4T). A 1-port T3/E3 network module (NME-1T1/E1) would occupy a network module slot. A Cisco 3925 router, shown in Figure 4 was filled in the same way, except that a Cisco Unity Express Advanced Integration Module (AIM2-CUE) was used instead of the network module (NME-CUE). In the Cisco 3925 configuration, the Cisco Unity Express AIM2-CUE module was placed into internal slot 1.

WAN Services Implementation
The following four configurations were tested for connecting WAN access lines to the nearest provider edge (PE) device of the service provider network:
•Single-Port DS-3 Interface with Frame Relay Encapsulation
•Single-Port DS-3 Interface with Point-to-Point Encapsulation
•Multiport DS-1 Interface with Multilink Point-to-Point Encapsulation
•Multiport DS-1 Interface with Multilink Frame Relay Encapsulation
•Onboard Gigabit Ethernet Interface
Single-Port DS-3 Interface with Frame Relay Encapsulation
A single-port clear-channel T3/E3 network module was used for this configuration. Traditional Frame Relay (FR) shaping was applied on the interface. Alternatively, QoS-based shaping as defined in the Eight-Class-V3PN-Edge-Shape service policy can be used. This example is shown in the "Multiport DS-1 Interface with Multilink Frame Relay Encapsulation" section.

LAN Services Implementation
The main design consideration in the branch office LAN design are high availability, scalability, security, and manageability. A multilayered LAN architecture addresses these criteria and makes it easier to troubleshoot network issues.
The Multilayered Branch LAN architecture can be divided into the following layers:
•Edge/Distribution Layer: Provides WAN connectivity, routing, addressing, high availability, quality of service (QoS), security, management services, and an exit point to the rest of the network.
•Access Layer: Provides connectivity and Power-over-Ethernet (PoE) to end user devices. Layer 2 security, authentication, private VLANs, trunking, and QoS are addressed at this layer.
Edge/Distribution Layer

Branch(config-if)#ip address 10.0.2.93 255.255.255.252 ! Assigns IP address to internal
Gigabit Ethernet link
Branch(config-if)#no shutdown

VLAN Trunking Protocol Implementation
VLAN Trunking Protocol (VTP) is a client server protocol that reduces the overhead of network administration by propagating the VLAN information from the server to all the clients in a single VTP domain.
In the Services Ready Medium Branch Network, the EtherSwitch service module at the distribution layer was configured as the VTP server.
Switch-Dist(config)# vtp domain VTP-BRANCH ! Creates VTP domain with name "VTP-BRANCH"
Switch-Dist(config)# vtp mode server ! Sets the distribution switch to server VTP mode
Note Always check the revision number of a new switch before bringing adding it to the network, regardless of whether the switch is going to operate in VTP client mode or operate in VTP server mode. To reset the revision number, do one of the following:
•Reboot the switch
or
•Temporarily change the domain name of the new switch and then change it back to its valid domain name.
VLAN Implementation
VLAN is a logical segmentation of LAN into multiple-broadcast domain that allows a group of hosts to communicate as if they were on a single LAN even if they are not physically collocated. A Layer 3 device is required for communication between VLANs.
Five VLANs were defined: DATA, VOICE, DMZ, MANAGEMENT, and BLACKHOLE.
Switch-Dist(config)# vlan 301 ! Creates Data VLAN to vlan database

A branch office router is likely to use a single routing protocol. However, because a network may use EIGRP, OSPF, RIPv2, BGP or static routing, all of these protocols were independently validated. The following configurations are for each of the protocols. Table 1 summarizes the subnets in the Services Ready Small Branch Network.
The Services Ready Small Branch Network provides direct access to the Internet through split tunneling. Various combinations of WAN services and VPN technologies lead to several different options for implementing the split tunnel mechanism. In WAN implementations where the network service provider is responsible for routing (for example, Layer 3 VPN [L3VPN]), split tunneling can be provided on the primary link and the backup link can be set to standby state. The implementation options vary slightly for GETVPN and DMVPN. In WAN implementations where the enterprise is responsible for routing, split tunneling can be provided on the backup link by maintaining it in an active state. Again, there is a slight variation between GETVPN and DMVPN implementations.
Active/Standby Primary/Backup WAN Links with DMVPN Implementation
The secondary WAN interface must be configured as the backup interface for the primary WAN link.
Router(config)# interface Multilink1 ! Enters multilink interface configuration mode
Router(config-if)# backup interface ATM0/2/IMA0 ! Specifies backup interface
Router(config-if)# exit
A loopback interface with a public address is used as the source interface for the DMVPN tunnel.
Router(config)# interface Loopback0 ! Enters loopback interface configuration mode
Router(config-if)# ip address 209.165.201.9 255.255.255.252 ! Specifies loopback subnet
Router(config-if)# exit
The "DMVPN Implementation" section provides configuration for the tunnel interface. After the tunnel interface is defined, two routing processes are configured: one for the enterprise network, and another for the public network. The following sections provide implementations in which OSPF, EIGRP, and RIPv2 provide routing for enterprise traffic in which BGP is responsible for routing public traffic.

Router(config-router)# network 10.0.2.88 0.0.0.3 area 0 ! Advertises WAAS subnet in backbone area
Router(config-router)# exit

Router(config-router)# version 2 ! Enable RIP version 2
Router(config-router)# network 10.0.0.0 ! Advertises all branch subnets
Router(config-router)# exit
Service Provider Routing with BGP
The BGP routing process is responsible for establishing the tunnel link by advertising the loopback network. In default BGP configuration, the router learns public routes advertised by the PE or ISP router. A large routing table would slow down the destination network lookup process. In general, network service providers should not advertise Internet routes to the branch network, but in case this happens, an access list is defined to exclude public routes.
Router(config)# access-list 20 permit 209.165.201.8 0.0.0.3 ! Permits Loopback network and blocks all others
Router(config)# router bgp 1 ! Enables public and loopback network BGP routing process
Router(config-router)# passive interface GigabitEthernet4/0 ! Disables routing
advertisements on the LAN interface
Router(config-router)# neighbor 192.168.0.2 remote-as 65015! Neighbor router IP for primary link that is in autonomous system 65015
Router(config-router)# neighbor 209.165.201.2 remote-as 65016! Neighbor router IP for backup link that is in autonomous system 65016
Router(config-router)# network 192.168.0.0 mask 255.255.255.252 ! Advertises primary WAN link subnet
Router(config-router)# network 209.165.201.0 mask 255.255.255.252 ! Advertises backup WAN link subnet
Router(config-router)# network 209.165.201.8 mask 255.255.255.252 ! Advertises Loopback subnet
Router(config-router)# distribute-list 20 in ! Block all routing updates except for Loopback network
Router(config-router)# exit
Finally, static routes are defined to direct traffic to the public network. When the primary link is active, it is used as the default route for all traffic. When the backup link is active, it is used as the default for all traffic.
Router(config)# ip route 0.0.0.0 0.0.0.0 192.168.0.2 ! Sets the primary WAN link as default for all traffic
Router(config)# ip route 0.0.0.0 0.0.0.0 209.165.201.2 ! Sets the backup WAN link as default for all traffic
Active/Standby Primary/Backup WAN Links with GETVPN on Primary Link and DMVPN on Backup Link Implementation
Because GETVPN is a tunnel-less protocol, it is used only on the primary WAN link. Because DMVPN is used for the backup link, the tunnel interface is needed only when the primary link fails. All enterprise network information is advertised over the primary link. Since this link also routes public traffic, it may insert public routes into the routing table. To prevent this situation, the following ACL is defined to allow only enterprise networks in the routing table.
Router(config)# access-list 10 permit 172.16.0.0 0.0.255.255 ! Permits all Enterprise networks
Enterprise Routing with OSPF
Enterprise networks are learned through the primary WAN interface.
Router(config)# router ospf 1 ! Enables private network OSPF routing process

Router(config-router)# distribute-list 10 in ! Block all Internet routing updates
Router(config-router)# exit

Router(config-router)# distribute-list 10 in ! Block all Internet routing updates
Router(config-router)# exit
Service Provider Routing with BGP
The BGP routing process is responsible for establishing the tunnel link by advertising the loopback network. In the default BGP configuration, the router learns public routes that are advertised by the ISP router. A large routing table would slow down the destination network lookup process. In general, network service providers should not advertise Internet routes to the branch network; an access list should be defined to exclude public routes.
Router(config)# access-list 20 permit 209.165.201.8 0.0.0.3 ! Permits Loopback network and blocks all others
Router(config)# router bgp 1 ! Enables public and loopback network BGP routing process
Router(config-router)# passive interface GigabitEthernet4/0 ! Disables routing
advertisements on the LAN interface
Router(config-router)# neighbor 209.165.201.2 remote-as 65016! Neighbor router IP for backup link that is in autonomous system 65016
Router(config-router)# network 209.165.201.0 mask 255.255.255.252 ! Advertises backup WAN link subnet
Router(config-router)# network 209.165.201.8 mask 255.255.255.252 ! Advertises Loopback subnet
Router(config-router)# distribute-list 20 in ! Block all routing updates except for Loopback network
Router(config-router)# exit
Finally, static routes are defined to direct traffic to the public network. When the primary link is active, it is used as the default for all traffic. When the backup link is active, it is used as the default for all traffic.
Router(config)# ip route 0.0.0.0 0.0.0.0 192.168.0.2 ! Sets the primary WAN link as default for all traffic
Router(config)# ip route 0.0.0.0 0.0.0.0 209.165.201.2 ! Sets the backup WAN link as default for all traffic
Active/Active Primary/Backup WAN Link with DMVPN Implementation
The primary function of the backup interface in the Services Ready Small Branch Network is to provide an alternate path in case the primary link fails. When the primary WAN interface is operational, the backup interface is in standby mode. However, for purposes of split tunneling, the interface can be kept in active state and provide access to the Internet, because it is a direct connection.
Again, there are two routing processes, one for enterprise traffic and another for public traffic. The routing is similar to the Active/Standby configuration for DMVPN because BGP likely selects the primary interface as the lowest-cost path to the central site network. It automatically switches over the tunnel interface to the backup link when the primary fails. To prevent situations where the Internet has a lower cost path to the central site, static routes with different costs are defined for the central site loopback interface. The only other difference in configuration is the default route configuration. Non-enterprise traffic must be directed out over the backup link.
Enterprise Routing with OSPF
Enterprise networks are learned through the tunnel interface.
Router(config)# router ospf 1 ! Enables private network OSPF routing process
Router(config-router)# passive interface GigabitEthernet4/0 ! Disables routing

Router(config-router)# exit
Finally, static routes are defined to direct traffic to the public network. When the primary link is active, it is used as the default for all traffic. When the backup link is active, it is used as the default for all traffic. In addition, static routes ensure that the central site loopback interface is routed over the primary link when it is in an active state.

Service Provider Routing with BGP
The BGP routing process is responsible for establishing the tunnel link by advertising the loopback network. In the default BGP configuration, the router learns public routes advertised by the ISP router. In general, network service providers should not advertise Internet routes to the branch network; an access list should be defined to exclude public routes.

There is a possibility that the tunnel link has a lower cost to the central site than the primary WAN link. To prevent traffic from being sent over the tunnel link when the WAN link is available, the tunnel interface is defined as backup for the primary WAN interface.

Quality of Service Implementation
Quality of service (QoS) identifies business-critical traffic and ensures that appropriate bandwidth and network resources are allocated according to a classification scheme. QoS includes classification of different traffic types, marking specific fields in Layer 2 or Layer 3 headers, prioritizing the traffic based on the marked field, and dropping unwanted traffic.
Eight-Class QoS was configured to match traffic, based on the NBAR protocol classification or using Layer 2 or Layer 3 header information. A different level of service is provided for the matched traffic. The QoS scheme also checks for any unwanted traffic and drops it if matches are found in the incoming traffic from the LAN. A parent policy-map is configured to shape the outgoing traffic to a specified rate (as per the service provider), and a child policy-map is applied to the shaping queue.

Infrastructure Protection Implementation
Securing Unused Ports
The following is an example of securing an unused port. The example applies to both of the access layer switches.
Switch(config)# interface g1/0/4 ! Enters configuration mode for the specified port
Switch(config-if)# switchport mode access ! Assign the port to access mode
Switch(config-if)# switchport access vlan 333 ! Assign the unused port to Black Hole VLAN
Switch(config-if)# exit
Turning Off Unused Services
To improve the overall security of the network, the Cisco IOS devices must be secured from infrastructure attack. As a security best practice, disable any unused services because these unused services are only rarely used for legitimate purposes and can be used to launch a denial of service (DoS) attack. The following example disables the unused services.
Router(config)# no service pad ! Disable PAD service
Router(config)# no service udp-small-servers ! Disable UDP small server
Router(config)# no service tcp-small-servers ! Disable TCP small server
Router(config)# no ip bootp server ! Disable BOOTP server
Router(confif)# no cdp run ! Disable Cisco Discover Protocol service
Router(config)# no ip source-route ! Disable source routing
Router(config)# no ip classless ! Disable forwarding of packets for unrecognized subnets
Router(config)# no ip http server ! Disable HTTP server
Router(config)# no ip http secure-server ! Disable HTTPS server
Router(config)# no ip domain-lookup ! Disable DNS server
Router(config) # interface Multilink1 ! Enters interface configuration mode
Router(config-if)# no cdp enable ! Disable Cisco discovery protocol on the interface
Router(config-if)# no ip redirects ! Disable ICMP redirect message
Router(config-if)# no ip proxy-arp ! Disable Proxy ARP
Router(config-if)# no ip unreachables ! Disable ICMP unreachable error message
Router(config-if)# no ip directed-broadcast! Disable directed broadcasts
Router(config-if)# no ip mask-reply! Disable ICMP mask reply messages
The unused services can also be disabled by running Cisco AutoSecure.

Access Control Implementation
Authentication, Authorization, and Accounting (AAA) is an architectural framework for consistently configuring a set of independent security functions. It provides a modular way of performing authentication, authorization, and accounting using a protocol such as RADIUS or TACACS.
In the branch architecture, AAA is the primary method for access control, using RADIUS as the protocol for communication between network devices and the AAA server.
Router(config)# aaa new-model ! Enables Authentication, Authorization and Accounting
services
Router(config)# aaa group server radius AAA-BRANCH ! Specifies the RADIUS server group
Router(config-sg-radius)# server 172.16.0.80 auth-port 1645 acct-port 1646 ! Specifies the
RADIUS server ip address
Router(config-sg-radius)# aaa authentication login default group radius local ! Specifies
default login authentication to use RADIUS server database
Router(config-sg-radius)# aaa authentication login VPN-AUTH-LIST group radius local !
Specifies SSL VPN login authentication to use RADIUS server database
Router(config)# aaa session-id common ! Specifies the use of the same session identifier
for all invocations of accounting services
Router(config)# radius-server key BRANCH-KEY ! Specifies RADIUS server key
Password Management
Router(config)# security passwords min-length 8 ! Sets minimum length of passwords to 8
characters
Router(config)# service password-encryption ! Enables Cisco IOS to encrypt all password in
configuration file
Router(config)# enable password level 7 C1$k0SyS ! Enables configuration password with

Secure Connectivity Implementation
Group Encrypted Transport Virtual Private Networks (GETVPN) eliminates the need for tunnels across the WAN. By removing the need for point-to-point tunnels, meshed networks can scale better while maintaining network-intelligence features that are critical to voice and video quality, such as QoS, routing, and multicast. GETVPN offers a new standards-based IPsec security model that is based on the concept of "trusted" group members. Trusted member routers use a common security methodology that is independent of any point-to-point IPsec tunnel relationship.
GET-based networks can be used in a variety of WAN environments, including IP and Multiprotocol Label Switching (MPLS). MPLS VPNs that use this encryption technology are highly scalable, manageable, and cost-effective, and they meet government-mandated encryption requirements. The flexible nature of GET allows security-conscious enterprises either to manage their own network security over a service provider WAN service or to offload encryption services to their providers. GET simplifies securing large Layer 2 or MPLS networks that require partial or full-mesh connectivity.
In the Services Ready Small Branch Foundation, GETVPN encryption was used on the primary WAN link.

DMVPN Implementation
Dynamic Multipoint Virtual Private Network (DMVPN) is useful for building scalable IPsec VPNs. DMVPN uses a centralized architecture to provide easier implementation and management for deployment that requires granular access control for diverse users including teleworkers and mobile workers.
Cisco DMVPN allows branch locations to communicate directly with each other over the public WAN or Internet, such as when using Voice over IP (VoIP) between two branch offices, but does not require a permanent VPN connection between sites. In the Services Ready Small Branch Network, DMVPN was tested on both the primary WAN link and the backup WAN link depending on whether the tunnel interface is active.

If AutoSecure was enabled on the router, then the next step is not necessary. However, if AutoSecure was not enabled, the above command will request a self-signed PKI certificate. To learn about creating self-signed certificates, visit:

Threat Defense Detection and Mitigation Implementation
•Zone-based Policy Firewall Implementation
Zone-based Policy Firewall Implementation
Zone-based Policy Firewall (ZPF) offers assignment of traffic into secure zones for multiple-interface routers. It changes the firewall configuration from interface-based classic Context-Based Access Control (CBAC) model to a more flexible zone-based configuration.
Interfaces are assigned to different zones, and inspection policies are applied to traffic moving between zones. As the inspection policies are zone based rather than interface based, different policies can be applied to traffic from and to the same interface.
There are four zones in the Services Ready Small Branch Network: Private (LAN), Public (WAN), VPN, and DMZ. Inspection policies were applied for the following zone pairs:
•Traffic originated from Private to Public
•Traffic originated from Private to DMZ
•Traffic originated from Public to Private
•Traffic originated from Public to DMZ
•Traffic originated from router to Private
•Traffic originated from Private to router
•Traffic originated from Private to VPN
•Traffic originated from VPN to Private

Router#
DMVPN uses Virtual Tunnel Interface (VTI) for IPsec VPN connectivity. When the DMVPN interface is assigned to a security zone, traffic routing to and from other interfaces in the router are subjected to zone-to-zone firewall policy.
If the DMVPN interface is assigned to the same security zone as another interface (for example, Gigabit Ethernet 0/0), traffic moving between hosts on the DMVPN and hosts connected to Gigabit Ethernet 0/0 will pass freely with no policy application.
In the Services Ready Small Branch Network, the tunnel interface is assigned to the VPN security zone. Additional inspection policies were applied.

Cisco IOS IPS Implementation
The Cisco IOS IPS acts as an inline intrusion detection sensor, watching packets and sessions as they flow through the router and scanning each packet to match any of the Cisco IOS IPS signatures. When Cisco IOS IPS detects suspicious activity, it responds before network security can be compromised and logs the event through Cisco IOS syslog messages or Security Device Event Exchange (SDEE).
In the Services Ready Small Branch Foundation, IPS inspection was enabled on the DATA VLAN in both directions. All types of traffic were inspected using advanced signature set stored in the flash memory.
Router# mkdir flash:ips5 ! Creates the folder in flash for saving the signature files
Router(config)# config t
Router(config)# ip ips config location flash:/ips5/ retries 1 ! Specifies the location to
save the signature file
Router(config)# ip ips deny-action ips-interface ! Changes the default behavior of the ACL
filters that are created for the deny actions.
Router(config)# ip ips notify SDEE ! Enables SDEE event notification on a router
Router(config)# ip ips name IPS-ADVSET ! Defines an IOS IPS rule
Router(config)# ip ips signature-category ! Allows the fine tuning of signature parameters
on the basis of signature category

Cisco Configuration Engine Implementation
There are several steps required to enable deployment with the Cisco Configuration Engine. First, bootstrap configuration must be applied to each device. The boostrap configuration is either preloaded or obtained from a centrally hosted DHCP server through option 150. In the Services Ready Small Branch Network, both routers and all switches were preloaded with the following bootstrap configuration.
Router(config)# cns trusted-server all-agents cce.example.com ! Specifies trusted server
for CNS agent
Router(config)# cns id hardware-serial ! Identifies this devices by its serial number to
CCE
Router(config)# cns id hardware-serial event ! Identifies this devices by its serial
number to CCE event logging component
Router(config)# cns event cce.example.com ! Enables event agent
Router(config)# cns config initial cce.example.com 80 ! Initiates an initial configuration
on CCE server port 80
Router(config)# cns config partial cce.example.com 80 ! Initiates an incremental
configuration on CCE server port 80
Router(config)# cns exec 80 ! Enables CNS agent
Switch-Access(config)# cns trusted-server all-agents cce.example.com ! Specifies trusted
server for CNS agent
Switch-Access(config)# cns id hardware-serial ! Identifies this devices by its serial
number to CCE

Switch-Access(config)# cns config initial cce.example.com 80 ! Initiates an initial
configuration on CCE server port 80
Switch-Access(config)# cns config partial cce.example.com 80 ! Initiates an incremental
configuration on CCE server port 80
Switch-Access(config)# cns exec 80 ! Enables CNS agent
Secondly, the device CNS ID must be entered into the CCE server prior to powering on of branch devices. Each device CNS is associated with Cisco IOS image to be loaded onto the device and a configuration toolkit. The Services Ready Small Branch Network provides following 10 CCE toolkits:
•Configuration for zero-touch deployment with Cisco Configuration Engine

The Services Ready Small Branch Networks has been tested with both SIP- and SCCP-enabled phones. Each phone type requires a different configuration. To implement SCCP-based phones, follow the SCCP instructions in the "Cisco Unified CME with SCCP Endpoints Implementation" section. To implement SIP-based phones, follow SIP instructions in the "Cisco Unified CME with SIP Endpoints Implementation" section.
To implement the various voice services described in the following sections, several resources are necessary at the central site. Table 2 lists these resources and the associated IP addresses that are used in the implementation instructions.

Cisco Unified CME with SCCP Endpoints: IP Phone Installation and Configuration
In the Services Ready Small Branch Network, IP Phones are installed by simply connecting them to ports on the access layer switches. Because all the ports offer Power-over-Ethernet, no additional power cables are necessary. After they are installed, the phones are configured with the default configuration that was generated during the telephony setup in the previous section. However, if the IP Phone firmware needs to be upgraded in the future, enter the following commands.

Cisco Unified SRST with SCCP Endpoints: Emergency Services Implementation
The following provides implementation of emergency number calling for North America. The PRI trunk is used to place emergency calls. Each 911 call is selectively routed to the closest Public Safety Answering Point (PSAP), based on the caller's location. In addition, the caller's phone number and address automatically display on a terminal at the PSAP. The PSAP can quickly dispatch emergency help, even if the caller is unable to communicate the caller's location. Also, if the caller disconnects prematurely, the PSAP has the information it needs to contact the 911 caller.

Cisco Unified SRST with SIP Endpoints: Emergency Services Implementation
The following example implements emergency number calling for North America. The PRI trunk is used for placing emergency calls. Each 911 call is selectively routed to the closest PSAP based on the caller's location. In addition, the caller's phone number and address automatically display on a terminal at the PSAP. The PSAP can quickly dispatch emergency help, even if the caller is unable to communicate the caller's location. Also, if the caller disconnects prematurely, the PSAP has the information it needs to contact the 911 caller.

Optimization Services Implementation
•Router and Cisco WAE Module Configuration
•Additional Cisco WAE-Application Accelerator Configuration
•Cisco WAE-Central Manager Implementation
Cisco WAAS Implementation
In the Services Ready Small Branch Network, the Cisco NME-WAE-522 network module was used to optimize the Common Internet File System (CIFS), FTP, and HTTP traffic.
Two types of configuration are applied to devices that run Cisco Wide Area Application Services (Cisco WAAS):
•Router and Cisco WAE module configuration
•Central manager configuration
After the router and module configurations are complete, the Cisco Wide Area Application Engine (Cisco WAE) module can be registered with the central manager. Registration with the central manager requires that all router configuration steps be complete, and that the Cisco WAE be able to connect to the central manager. After the Cisco WAE has been registered and activated with the central manager, all additional configuration options can be set through the central manager device groups.
The central manager configuration provides the remaining configuration for the entire Cisco WAAS deployment. The central manager configuration options can be applied at the device or device group level. To simplify the deployment and management of the Cisco WAAS solution, the Services Ready Small Branch Network uses device groups as the primary central manager configuration method.
Router and Cisco WAE Module Configuration
The router provides Cisco Web Cache Communication Protocol (Cisco WCCP) interception points for Cisco WAAS. Cisco WCCP redirection allows the router to redirect traffic to Cisco WAAS for optimization. Various methods of interception and redirection are supported by routers and switches. Redirection methods depend on the speed requirements and the router or switch platform. This deployment uses both generic router encapsulation (GRE) redirection and Layer 2 (L2) redirection.
The loopback interface on the router is essential for identifying the router ID. Although any IP address can be used to identify the router ID, the loopback interface is preferred over the physical interfaces. Loopback interfaces are always available, and there are no physical ties to them. Other routing protocols also use loopback interfaces as the preferred method for naming the router ID. If the IP address is tied to a specific physical interface, and the physical interface fails, then the IP address becomes unavailable, causing unexpected problems for the Cisco WCCP groups.
The Cisco WCCPv2 services 61 and 62, also known as TCP promiscuous mode services, allow the Cisco WCCP to transparently intercept and redirect traffic to the Cisco WAE module. Service 61 redirects ingress traffic, and service 62 redirects egress traffic. Services 61 and 62 are both needed to redirect bidirectional traffic flow. Passwords should be assigned to Cisco WCCP groups to prevent rogue traffic interception and redirection.

Activating the Application Accelerators
For security purposes, Cisco WAEs that are being added to the Cisco WAAS network need to be approved by the Cisco WAAS network administrator. This security feature prevents unauthorized devices from joining the Cisco WAAS network. This section provides steps for activating all the inactive devices.
To activate the devices, from the Cisco WAAS Central Manager window, choose Devices > Devices.
1. In the taskbar, click the Activate All Inactive WAEs icon, shown in the red box in Figure 37, to activate the two inactive Cisco WAEs.
Figure 37 Devices Window
2. The Activate All Inactive WAE window appears, as shown in Figure 38. By default, the Create a new location for each inactive WAE option is chosen.
Figure 38 Activating Inactive Cisco WAEs
3. Click Submit at the bottom of the page.
4. When a Transaction Warning dialog box appears, click OK, and then click Submit. The current state of the core and edge Cisco WAEs is now listed as pending instead of inactive, as shown in the red box in the middle of Figure 39. Notice in the red box at the top of the Figure 39 that the system status has changed to orange, with two devices reporting Major.

Cisco WAE-Central Manager Implementation
The central manager is the management component of Cisco WAAS. The central manager provides a GUI for configuration, monitoring, and management of multiple branch-office and data center Cisco WAEs. The central manager can scale to support thousands of Cisco WAE devices for large-scale deployments. The central manager must be used in order to make configuration changes through the web interface. If the central manager fails, the Cisco WAEs continue to function; however, changes cannot be made using the web pages on the central manager until the central manager comes back online.
The Cisco WAEs need to connect to the central manager at the initial setup. The registration process adds the Cisco WAE to the central manager and initializes the local Cisco WAE database. When disk encryption on the Cisco WAE is enabled, the central manager must be available to distribute the encryption key if the Cisco WAE reboots.
Centralized reporting can be obtained from the central manager. Individually, the Cisco WAEs provide basic statistics through the CLI and local-device GUI. Systemwide application statistics are available from the central manager GUI. Detailed reports such as total traffic reduction, application mix, and pass-through traffic are available from the central manager GUI.
