RFC 7606: BGP enhanced error handling

This feature supports RFC 7606 to provide improved security and robustness in the processing of errors in the BGP Update messages that are received from peer routers. In the earlier releases, the Rib agent would reset the BGP peering session according to RFC 4271 (BGP for IPv4) and RFC 4760 (Multi-protocol BGP) if it detected errors in the BGP Updates received from a given peer. This feature will provide the following new functionality:   Treat-as-withdraw: In certain scenarios, the malformed BGP Update will be treated in such a way that all contained routes have been withdrawn by the peer instead of being installed in...

BGP Prefix Independent Convergence Enhancements for IBGP

The BGP Prefix Independent Convergence (PIC Edge) is an existing feature that was first introduced in EOS-4.15.0F. This feature refers to fast re-convergence of traffic destined for BGP prefixes on a network event affecting the best path(s) such that the time taken to switch traffic from the active best path(s) to the next best path (i.e. backup path) is independent of the number of prefixes. The above behavior is achieved by pre-programming the best path and alternate backup path in the forwarding agent in steady state. It is supported for both IPv4 and IPv6 address families for default and non-default VRFs....

BGP PIC Edge is supported only when the best path is a single-hop...
