By using a general protocol that allows for sharing of bidirectional forwarding detection (BFD) state across a shared path between neighboring routers, scale, simplicity and flexibility in designs may be achieved with at least a 2:1 ratio compared to a traditional implementation. Each participating node hosts BFD sessions that monitor a locally attached link and then shares the state of the BFD sessions to other neighboring nodes, effectively proxying the BFD state for consumption by participating devices in an efficient manner.
