Abstract:
Techniques are described for verifying the connectivity status of multiple paths through a computer network. The techniques may be useful in testing the connectivity of label switched paths (LSPs), and particularly useful point-to-multipoint (P2MP) LSPs. In some embodiments, a P2MP label switched path (LSP) ping protocol may be used a first connectivity verification protocol for the P2MP LSP and a Multipoint Bidirectional Forwarding Detection (MP BFD) protocol may be used as a second connectivity verification protocol. In addition, use of the LSP ping protocol for connectivity testing of the P2MP LSP may be used to boot-strap session information for MP BFD sessions with egress devices of the P2MP LSP.
