Feature provides a way to set the Passive role in BFD session initialization. A system taking the Passive role does not begin sending BFD control packets for a particular session until it has received a BFD packet for that session, and thus has learned the remote system's discriminator value.

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.

This is achieved by using the next-hop of the static route as the peer IP address for the BFD session. The static route is either installed or removed based on the status of the underlying BFD session. A static route whose next-hop is configured to be tracked by BFD is referred to as a ‘BFD tracked static route’ in the context of this document. This feature is supported for both IPv4 and IPv6 static routes.

This feature adds support for offloading BFD Transmit path to hardware (ASIC) for specific types of BFD sessions. This will improve accuracy of transmit timer implementations for BFD (especially with fast timers like 50 ms) and relieve pressure on the main CPU in scenarios of scale.

This feature provides the capability to specify the label stack of the return path from the S-BFD reflector to the S-BFD initiator on the S-BFD initiator, which can be a different path from the shortest/best IGP path from the S-BFD reflector back to the S-BFD initiator, in order that the forwarding of the S-BFD packets would not be impacted by IP routing convergence, i.e., the stability of S-BFD session is not impacted by the IP routing convergence time.
