Abstract

See full text

A network device configures a unique ring number for each interface in a ring network and stores the ring number. The network device receives a RSVP confirmation packet from a next-hop network device, storing a route object record contained in the RSVP confirmation packet. The network device parses the route object record of the primary tunnel, searches for an end network device on the primary tunnel in the same ring network, sets the end network device as a destination network device of a protection tunnel of the network device, sets the network device as a start network device of the protection tunnel, and store path information of the protection tunnel. An interface of the end network device has the same ring number with an egress interface of the network device.
