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.
