Client Data Tunneling

Ethernet over GRE Tunnels

Ethernet over GRE (EoGRE) is an aggregation solution for aggregating Wi-Fi traffic from hotspots. This solution enables customer premises equipment (CPE) devices to bridge the Ethernet traffic coming from an end host, and encapsulate the traffic in Ethernet packets over an IP GRE tunnel. When the IP GRE tunnels are terminated on a service provider broadband network gateway, the end host’s traffic is terminated and subscriber sessions are initiated for the end host.

High Availability (HA) is supported for EoGRE IPv4 and IPv6 tunnel configuration. In addition, Client SSO is supported for IPv4 and IPv6 EoGRE tunnel clients.

For more information about designing and deploying EoGRE on controller and Cisco FlexConnect APs, see the EoGRE Deployment Guide.

Central	Local	Standalone	New clients cannot join. Existing clients should work.
Central	Local	Boot in Standalone	Clients cannot join.

Changing the Tunnel Source

Prior to Release 8.2, the management IP address was used as the tunnel endpoint. Release 8.2 has enabled the specification of any L3 dynamic interface other than the management interface as a tunnel endpoint, if need be.

Support for IPv6

In Release 8.3, support is added for client IPv6 traffic and IPv6 address format for the EoGRE tunnel gateway. Client IPv6 traffic is supported on both IPv4 and IPv6 EoGRE tunnels. A maximum of eight different client IPv6 addresses are supported per client. Controllers send all the client IPv6 addresses that they have learned to the Accounting server in the accounting update message. All RADIUS or Accounting messages exchanged between controllers and tunnel gateways or RADIUS servers are outside the EoGRE tunnel.

Restrictions for EoGRE Tunneling

EoGRE tunneling is not supported on Cisco 2504 WLC.
On Cisco vWLC, EoGRE tunneling is supported only in local switching mode.
EoGRE feature is not supported in Cisco Aironet 702, 801, 802, 1520 Access Points.
It is not possible to edit or delete a tunnel profile if the profile is associated with a WLAN. You must first dissociate the profile from the WLAN and then edit or delete the profile.
It is not possible to edit or delete a tunnel gateway if the gateway is already associated with a domain. You must first dissociate the tunnel gateway from the domain and then edit or delete the tunnel gateway.
It is not possible to edit or delete a domain if the domain is already associated with a tunnel profile rule. You must first dissociate the domain from the tunnel profile rule and then edit or delete the domain.
If the domain is modified on the fly, the client associated with the domain is deauthenticated.
We recommend that you do not have firewall that could block ICMP packets.
Tunnel Gateway (TGW) as AAA and RADIUS realm feature on WLAN should not be used together.
Tunnel Gateway (TGW) as AAA is not supported on EoGRE for FlexConnect APs.
Due to SNMP limitation, tunnel gateway names can be up to 127 characters only.
For open WLANs, the profile must have only one rule, which is a * rule. Mapping of a profile that has multiple rules to an open authentication WLAN is not supported.
EoGRE client gets IPV6 address from local switching VLAN.
Broadcast/Multicast traffic on Local Switching VLAN reaches EoGRE clients.
FlexConnect+Bridge Mode is not supported.
Standalone mode: EoGRE client Fast Roaming is not supported.
WebAuth is not supported.
FlexConnect AP Local Authentication is not supported.

After Fault Tolerance, client type is SimpleIP. It is changed to EoGRE after a period of 30 seconds.
MTU of AP gateway should be 1500 bytes.
Lightweight APs support Path MTU only for EoGREv6. For EoGREv4, it is not supported.
EoGRE IPv6 Restrictions:
- EoGRE client gets IPv6 address from local switching VLAN
- DHCP Option 82 configuration is not supported on IPv6 clients.
- Applications such as RADIUS, FTP, TFTP, SFTP, LDAP, SXP, syslog, and so on, are supported on only management IPv6 address.
- Dynamic IPv6 AP-manager interface is not supported.
- Dynamic interface with IPv6 supports only as tunnel interface.
- Maximum number of dynamic interface to which IPv6 address can be assigned is16.
- The IPv6 link local addresses are common for all switched virtual interfaces (SVI) on a switch. Due to this, configuring an IPv6 address on dynamic address fails. To overcome this issue, you must explicitly configure link local address on the uplink switch for SVI. Each SVI should have unique link local address configuration.
- The IP packets on IPv6 tunnels has a maximum size limit of 1280 bytes on controller.
Clients connecting to Wave 2 APs get an IP address from the native VLAN in the conditions described in CSCvu46349.

Configuring EoGRE on the Controller (GUI)

Procedure

Step 1

Create tunnel gateways and configure heartbeats:

Choose Controller > Tunneling > EoGRE.
Select the Interface Name.

Interface present on the controller to be used as a source of the tunnel.
Set the Heartbeat Interval. The default interval is 60 seconds.

The controller sends keepalive pings every 60 seconds.
Set Max Heartbeat Skip Count. The default value is set to 3.

If the TGW does not reply after three keepalive pings, the controller marks the TGW as nonoperational. The number of skip count decides how many times the TGW can skip consecutive replies, before the controller knows that the TGW is nonoperational.
Specify a TGW Name.
Specify the TGW IP Address.

Both IPv4 and IPv6 address formats are supported. You can create up to 10 such tunnel gateways.
Specify a Domain Name.
Specify the tunnel gateway that you created, and click Add.

If the tunnel gateway is reachable, the state should be displayed as UP under the TGW List.

Domain represents a virtual collection of one or more tunnels used for redundancy purposes. Up to 16 tunnels can exist in a domain. If one tunnel fails, the traffic is redirected to another TGW.

Step 2

Create a tunnel profile:

Choose Controller > Tunneling > Profiles.
Specify a profile name and click Add.

The profile name is displayed under Profile List.

Step 3

Define a tunnel profile rule:

Click the tunnel profile that you created.
Under the Rule tab, to map a specific realm to the profile, enter the realm name. A realm is a string after @, for example, user_name@realm. To match any Realm, use *, which means all realms are accepted.
Choose Tunnel Type as EoGRE.
Set VLAN to 0.
Choose the Gateway Domain that you created in Step 1.
Click Add to add the rule to the tunnel profile.

Step 4

Specify tunnel parameters:

Under the Tunnel Parameters tab, check the Gateway as AAA Proxy and Gateway as Accounting Proxy (optional) check boxes to configure a tunnel gateway as a AAA proxy and as an Accounting proxy.

(Optional) Check the DHCP Option-82 check box.

Note

DHCP Option 82 configuration is not supported on IPv6 clients.

Choose the DHCP Option 82 format as either Binary or ASCII.
Specify the DHCP Option 82 Delimiter. The default is ;.
Specify the Circuit-ID and Remote-ID information. You can choose up to five fields each and sort them accordingly.
Click Apply.

Step 5

Create RADIUS Authentication or Accounting servers or both by specifying the tunnel gateway IP addresses that you specified in Step 1 as the server IP addresses, and enable Tunnel Proxy.

For instructions on how to create RADIUS servers, see the Configuring RADIUS chapter under Security Solutions.

Step 6

Associate the tunnel profile to the WLAN:

Choose WLANs and click the WLAN ID to which the tunnel profile has to be associated.
In the Advanced tab, under Tunneling, choose the Tunnel Profile.
(Optional) You can choose to enable AAA Override for the WLAN, which means that the controller is allowed to accept the attributes returned by the RADIUS server.
Save the configuration.

Step 7

Verify if the tunnel is correctly configured:

Choose Controller > Tunneling > Profiles.
Verify if the profile name is mapped to the correct WLAN.

Proxy Mobile IPv6

Proxy Mobile IPv6 (PMIPv6) is a network-based mobility management protocol that supports a mobile node by acting as the proxy for the mobile node in an IP mobility-related signaling scenario. The mobility entities in the network track the movements of the mobile node, initiate mobility signaling, and set up the required routing state.

The main functional entities are the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG). The LMA maintains the reachability state of the mobile node and is the topological anchor point for the IP address of the mobile node. The MAG performs mobility management on behalf of a mobile node. The MAG resides on the access link where the mobile node is anchored. The Cisco Wireless LAN Controller (WLC) implements the MAG functionality.

In the Cisco 5508 WLC, Cisco WiSM2, and Cisco 8510 WLCs, PMIPv6 MAG support for integration with LMA such as Cisco ASR 5000 Series in cellular data networks.

For PMIPv6 clients, Cisco WLC supports both central web authentication and local web authentication.

PMIPv6 is supported for clients with 802.1X authentication. After the 802.1X authentication is complete, a Cisco AP starts PMIPv6 signaling for the corresponding client.

MAG on AP is supported on FlexConnect mode APs in a locally switched WLAN. For PMIPv6 clients, all the data traffic from clients is tunneled to the LMA in the Generic Routing Encapsulation (GRE) tunnel established between the MAG and the LMA. Similarly, all the packets received from the LMA in the GRE tunnel are routed to the wireless client.

After the 802.1X authentication is complete, the Cisco AP starts PMIPv6 signaling for the client. In a MAG-on-AP scenario, the Cisco AP starts PMIPv6 signaling. In a MAG-on-WLC scenario, the Cisco WLC starts PMIPv6 signaling.

Fast Roaming with Central Association

Fast roaming is supported when central association is enabled on WLANs. When central association is enabled, all key cachings occur on the Cisco WLC. When a PMIPv6 client roams from one AP to another on the same mobility domain, the Cisco WLC sends the PMIPv6 parameters of the client to a new AP in PMIPv6 tunnel payload to start PMIPv6 signaling. Also, the Cisco WLC sends the PMIPv6 tunnel payload to the old AP to tear down the Generic Routing Encapsulation (GRE) tunnel for the client with the LMA. Fast roaming is supported in both intra-Cisco WLC and inter-Cisco WLC roaming scenarios and mobility messages are added to send PMIPv6 parameters from one Cisco WLC to another during roaming.

Client roaming from third-party MAG to Cisco AP-MAG is similar to a new client joining; a client roaming away from a Cisco AP-MAG to a third-party MAG is similar to a client leaving, and therefore, requires no special handling.

With Cisco APs in FlexConnect mode, all reassociation requests from clients are handled by the Cisco APs themselves. However, if central association is enabled, all reassociation requests are handled by the Cisco WLC.
