BGP triggered IP-in-GUE Encapsulation provides a mechanism for dynamically creating tunnels in a core network using an IP underlay.  IP-in-GUE (Generic UDP Encapsulation) encapsulates IP traffic in an IPv4/UDP header.  IP unicast routes to destinations reachable across the core network are learned via BGP at the ingress edge.

This feature adds support for BGP UCMP in the multi agent routing protocol model. The TOI for BGP UCMP in the ribd

Unequal Cost Multi Path (UCMP) for BGP is a mechanism for forwarding traffic from a device for an ECMP route in the ratio

Bidirectional Protocol Independent Multicast (PIM) allows routers to build trees to deliver multicast traffic from sources to receivers. It is a variant of sparse-mode PIM that efficiently addresses the use case where receivers for a multicast group are also sources for that group. While sparse-mode PIM builds shared trees and source-specific trees, bidirectional PIM only builds shared trees. A shared tree for a multicast group is rooted at the Rendezvous Point (RP) for that group. The RP for a bidirectional group is an IP address, which may or may not be real, but is reachable via all routers in the multicast domain. There may be multiple RPs in a multicast domain.

With the 14.0 release, CV-CUE brings the ability to create checkpoints to save your current configurations, profiles, and settings. Creating and restoring a checkpoint is possible for all configuration settings available in CV-CUE. You can create a checkpoint for location based configurations, group configurations, or global configurations. For all the configurable settings that are available for a network, you can create a checkpoint to save it. 

With the 20.0 release, the checkpoint feature in CV-CUE also captures custom attributes created on the child or parent location. When you create a checkpoint for a location that has custom attributes, the custom value is also captured in the saved checkpoint.

This feature allows failover to the backup path to occur in constant time per interface going down for features such as RSVP link protection, RSVP node protection, TI-LFA link protection, and BGP PIC. Without this feature enabled, it would take time proportional to the number of paths going over the interface experiencing the link down event to failover to the backup path. With this feature enabled, the failover time would be constant regardless of the number of paths.

Class based forwarding (CBF) is a means for steering network traffic into colored tunnels based on one or more fields of the ingress traffic. Rephrased, CBF is forwarding of traffic based on “classes” which are derived from fields in the ingress packet headers and policies provisioned on the router.

Class Based Forwarding (CBF) provides a means for forwarding traffic through selected tunnels based on the traffic class of the incoming packet. Starting 4.32.2F CBF supports forwarding MPLS labeled traffic based on the EXP value in the incoming packet or the internal traffic class (TC) resolved from the parameters of the packet (e.g TC derived from EXP bits combined with port trust mode). Here, EXP bits refer to the Experimental bits in the MPLS header.
