OAM LABEL SWITCHED PATH FOR FAST REROUTE OF PROTECTED LABEL SWITCHED PATHS |
摘要 |
In response to receiving a reply message for reserving bandwidth along a primary path for a first label switched path (LSP) for carrying data traffic from an ingress network device to an egress network device, a point of local repair (PLR) network device establishes a second LSP from the PLR to a merge point (MP) network device along a subset of the primary path. The second LSP is dedicated to carrying operations, administration and management (OAM) messages to verify connectivity of the subset of the primary path, and is not used for sending data traffic. The PLR sends an OAM message to verify connectivity of at least one protected resource along the subset of the primary path to a next hop along the second LSP, wherein the OAM message is encapsulated by a second label associated with the second LSP.
