Abstract:
RFC 4090 specifies an RSVP facility-backup fast reroute mechanism for
protecting LSPs against link and node failures. This document
extends the mechanism to provide so-called "setup protection" for
LSPs during their initial Path message signaling time. In
particular, it enables a router to reroute an LSP via an existing
bypass LSP, when there is a failure of the immediate downstream link
or node along the desired path. Therefore, it can be used to avoid
LSP signaling failure and reduce setup time in such kind of
situation, and allow an LSP to be established temporarily over a
bypass LSP when an alternative path can only be resolved at a much
later time.
