Abstract:
Label Distribution Protocol (LDP) is widely deployed to signal Label
Switched Paths (LSPs) due to its simple operational model. Since LDP
establishes LSPs along IGP routed paths, its failure recovery is
gated by the interior gateway protocol's (IGP's) re-convergence.
Though some mechanisms exist to do Fast Re-route (FRR) of LDP LSPs,
they suffer from significant complexity or lack of full coverage or
both. This document describes a method to perform FRR of LDP LSPs
that retains the simple operational model of LDP. The goal is to
provide 100% coverage for all failure scenarios including Shared Risk
Link Group (SRLG) failure with recovery characteristics similar to
the methods in Resource Reservation Protocol - Traffic Engineering
FRR (RSVP-TE-FRR).
