Seamless Bidirectional Forwarding Detection (S-BFD) is a simplified BFD mechanism. It eliminates most negotiation aspects and provides advantages such as fast configuration injection. S-BFD is especially useful in multi-homing PE scenarios and reduces resource overheads on the dual-homing PEs. Although S-BFD is simpler than BFD, a large number of manual configurations are required when there are a large number of PEs. This document provides the mechanism of distributing S-BFD discriminators with VPN service routes, which simplifies S-BFD deployment for VPN services.
