LSP ping and traceroute for bypass tunnels

摘要

A method performed by a network device may include assembling a multiprotocol label switching (MPLS) echo request, the echo request including an instruction for a transit node to forward the echo request via a bypass path associated with the transit node, and an instruction for an egress node to send an echo reply indicating that the echo request was received on the bypass path. The method may also include sending the MPLS echo request over a functioning label switched path (LSP).

主权项

1. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions which, when executed by a processor, cause the processor to:
assemble an echo request for a functional label switched path (LSP),
the echo request including directions for a transit node in the functional LSP to forward the echo request via a bypass path associated with the transit node and directions for an egress node of the LSP to send an echo reply that indicates that the echo request was received,
the echo request including an indication to forward the echo request along a Resource Reservation Protocol (RSVP) bypass path; andsend the echo request to the transit node via the functional LSP.
