Abstract
An egress network device of a point-to-point (P2P) tunnel can receive an LSP Ping message via the P2P tunnel from an ingress network device of the P2P LSP, wherein the LSP Ping message specifies a label that the egress network device associates with a service provided to the egress network device via the P2P tunnel. In response to receiving the LSP Ping message, the egress network device can store an association between the label and the P2P tunnel. The egress network device also uses a fault detection network protocol session over the P2P tunnel to monitor a state of the P2P tunnel. In response to detecting based on the fault detection network protocol session that the state of the P2P tunnel is down, the egress network device determines the service is unavailable from the ingress network device via the P2P tunnel, and selects a new source to provide the service.
