Bidirectional Forwarding Detection (BFD) is expected to be able to monitor wide variety of encapsulations of paths between systems. When a BFD session monitors an explicitly routed unidirectional path there may be a need to direct egress BFD peer to use a specific path for the reverse direction of the BFD session.
