Abstract:
For a Traffic Engineered (TE) point-to-multipoint (P2MP) Label
Switched Path (LSP), it is preferable in some cases to re-evaluate
and re-optimize the entire P2MP-TE LSP by re-signaling all its
Source-to-Leaf (S2L) sub-LSP(s). Existing mechanisms, a mechanism
for an ingress Label Switched Router (LSR) to trigger a new path re-
evaluation request and a mechanism for a mid-point LSR to notify an
availability of a preferred path, operate on an individual or a sub-
group of S2L sub-LSP(s) basis only.
This document defines RSVP-TE signaling extensions to allow an
ingress node of a P2MP-TE LSP to request the re-evaluation of the
entire LSP tree containing one or more S2L sub-LSPs whose paths are
loose (or abstract) hop expanded, and for a mid-point LSR to notify
to the ingress node that a preferable tree exists for the entire
P2MP-TE LSP. This document also defines markers to indicate
beginning and end of a S2L sub-LSP descriptor list when RSVP message
needs to be fragmented due to large number of S2L sub-LSPs when
performing re-optimization.
