Aggregate storm control with traffic class option provides the capability to rate limit BUM(Broadcast, Unknown

This document describes BFD RFC7130 mode on EOS. RFC7130 defines a mechanism to run BFD protocol over port channels with an independent asynchronous BFD session on every port channel member link. With RFC7130 support, the port channel member link will be removed from forwarding if the BFD session state transitions from UP to DOWN on the member link. This is useful for quickly detecting failures where L1 stays connected but the interface is unable to forward traffic.

IPv6 support for BFD in ISIS. BFD provides a faster convergence in scaled deployments where using aggressive times

BGP Add Path TX allows for a BGP speaker to advertise multiple paths (instead of a single best path) for a prefix towards

The default policy behavior is to permit/accept all routes when a BGP neighbor or peer group is configured with a route

The BGP Prefix Independent Convergence (PIC Edge) is an existing feature that was first introduced in EOS 4.15.0F.

This is an addition to the SSL certificate and key management feature added in EOS 4.15.0F.

LACP on Loopback Interfaces allows for Active Port Channels on one or more interfaces whose link endpoints terminate

On a MLAG chassis, MAC addresses learned on individual peers are synced and appropriate interfaces are mapped to these MAC addresses. In case of unexpected events like reloading of one of the peers in the MLAG chassis or flapping of one or more MLAG interfaces, some loss of traffic may be observed.

If an MLAG flaps on one peer, then we may have to remap the MAC addresses learned, such that the reachability is via the
