Configuration of
Proactive Operations, Administration, and Maintenance (OAM) Functions
for MPLS-Based Transport Networks Using RSVP-TE
Abstract
This specification describes the configuration of proactive MPLS
Transport Profile (MPLS-TP) Operations, Administration, and
Maintenance (OAM) functions for a given Label Switched Path (LSP)
using a set of TLVs that are carried by the GMPLS RSVP-TE protocol
based on the OAM Configuration Framework for GMPLS RSVP-TE.
