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.
