In asynchronous mode, either BFD peer can initiate a BFD session. IPv6 encapsulation is supported. BFD works only for directly-connected neighbors. BFD neighbors must be no more than one IP hop away.

Nov 01, 2019 · The purpose of Bidirectional Forwarding Detection (BFD) is to detect a failure (hop or multi-hop) and act on it based on the timers configured/negotiated between the BGP peers. As soon as the hold timer elapsed, the peer is taken down, and reconvergence is triggered, in the meanwhile traffic is not passed through the link where the BFD session ...
