ABSTRACT:
In one embodiment, a method generally includes establishing a routing protocol peer relationship and a Bidirectional Forwarding Detection (BFD) session with a neighbor node, receiving a DOWN BFD event signal from the neighbor node, and maintaining a routing protocol adjacency down state following successful exchange of routing protocol packets with the neighbor node. An apparatus for maintaining protocol adjacency state with a forwarding failure is also disclosed.
