IP Multicast: Multicast

Multicast SLA Measurment with MLDP

Display of aggregated egress multicast stats for BDI interfaces on Head node, which is part of the MLDP core is supported.

IP Routing: Protocol-Independent

On-Change Notifications for IS-IS State

This feature allows you to externalize the internal state of the router for the operational data and thus enables you to access the internal state of the router. It helps in sending on-change notifications to the receiver for any change of state, for example, when the adjacency goes up or down.

Segment Routing

L2VPN over SR-TE Preferred Path

This feature allows you to configure an SR policy as the preferred path for a VPWS or VPLS pseudowire. VPWS or VPLS pseudowires between same PEs can be routed over different SR policies based on the requirements. Prior to this release, you could only steer the traffic using the SR policy for routing IPv4 traffic to a destination pseudowire (over IGP or BGP-LU).

PCE Initiated SR Policy with OSPF Autoroute Announce

This feature enables a steering mechanism in which IGPs automatically use the policy for destination's downstream of the policy end point.

Segment Routing Flexible Algorithm support for TI-LFA uLoop Avoidance, SID Leaking, and ODN with Auto-Steering

This feature allows you to compute Loop Free Alternate (LFA) paths, TI-LFA backup paths, and Microloop Avoidance paths for a particular Flexible Algorithm using the same constraints as the calculation of the primary paths for such Flexible Algorithms, for IS-IS.

Inter-area leaking of Flexible Algorithm SIDs and prefixes and selectively filtering the paths that are installed to the MFI are also supported.

Telemetry (Model-Based Telemetry and Event-Based Telemetry) Support for Performance Measurement

This feature enables Model-Based Telemetry (MDT) and Event-Based Telemetry (EDT) that allow the data to be directed to a configured receiver. This data can be used for analysis and troubleshooting purposes to maintain the health of the network.

The sr_5_label_push_enable SDM template is mandatory for this feature to function.

MPLS Basic

Re-optimization with Tunnel Bandwidth Modification on Flex-LSP Protect Path

This feature supports Make Before Break (MBB) functionality and thus ensures there is no traffic loss when a MPLS Flex LSP tunnel runs on protect LSP (if working LSP goes down) and the tunnel bandwidth is modified.

When the working LSP comes up, use the following command to manually switch from the working to protect LSP: mpls traffic-eng switch tunnel tunnel-ID .

IP SLAs

Configurable User-Defined and EMIX Packet Size

SAT based support for configurable EMIX traffic pattern in FPGA

Support for EMIX packet size is enhanced. For EMIX traffic, packet sizes of 64, 128, 256, 512, 1024, 1280, 1518, Maximum Transmission Unit (MTU) and user-defined patterns are supported. These packet sizes are forwarded in ratio of 1:1:1:1:1.

IP Routing: BFD

BFD over G8032 and Multi EFP BDI

Scale numbers for BFD and hardware offload are enhanced for the Cisco RSP2 and Cisco RSP3 modules.

High Availability

Secondary ROMMON Partition Auto Upgrade

This feature supports secondary ROMMON partition auto upgrade after a successful primary ROMMON partition is complete for NCS 4216 routers.

Cisco NCS 4200 Series Software

CCP User Secret and Enable Secret masking

To support Common Criteria Policy validation for the masked secret.

Increase Maximum MTU Size

Maximum Transmission Unit (MTU) is increased to a maximum of 9644 bytes on the Cisco RSP3 module. You can configure the MTU bytes using the mtu bytes command.

VLAN Translation for RSP3

VLAN translation provides flexibility in managing VLANs and Metro Ethernet-related services. You can configure 1:1 and 2:1 VLAN translations using the sdm prefer enable_vlan_translation command on the Cisco RSP3 module.
