Technical Summary
MPLS-TE Graceful Shutdown is a method for explicitly notifying
the nodes in a Traffic Engineering (TE) enabled network that the
TE capability on a link or on an entire Label Switching Router
(LSR) is going to be disabled. MPLS-TE graceful shutdown
mechanisms are tailored toward addressing planned outage in the
network.
This document provides requirements and protocol mechanisms to
reduce/eliminate traffic disruption in the event of a planned
shutdown of a network resource. These operations are equally
applicable to both MPLS and its Generalized MPLS (GMPLS)
extensions.
This document explains usage of existing protocol mechanisms to
support a "Graceful Shutdown" operation. No new protocol mechanisms
are defined
Working Group Summary
The document was significantly revised to be in line with
draft-ietf-mpls-gmpls-lsp-reroute. Much of the WG discussion focused
on this. Once alignment was agreed upon, there was no significant
disagreement.
Document Quality
There are no known implementations or planned implementations of this
work.
