Graceful Shutdown in MPLS and Generalized MPLS Traffic Engineering Networks
RFC 5817, “Graceful Shutdown in MPLS and Generalized MPLS Traffic Engineering Networks”, is an Informational document published in April 2010 by Z. Ali, JP. Vasseur, A. Zamfir, J. Newton. The canonical text is published by the RFC Editor.
Abstract
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 or eliminate traffic disruption in the event of a planned shutdown of a network resource. These operations are equally applicable to both MPLS-TE and its Generalized MPLS (GMPLS) extensions. This document is not an Internet Standards Track specification; it is published for informational purposes.
