The Border Gateway Protocol (BGP) is heavily used in Service Provider
networks for both Internet and BGP/MPLS VPN services. For resiliency
purposes, redundant routers and BGP sessions can be deployed to reduce
the consequences of an Autonomous System Border Router (ASBR) or BGP
session breakdown on customers' or peers' traffic. However, simply
taking down or even bringing up a BGP session for maintenance purposes
may still induce connectivity losses during the BGP convergence. This
is no longer satisfactory for new applications (e.g., voice over IP,
online gaming, VPN). Therefore, a solution is required for the
graceful shutdown of a (set of) BGP session(s) in order to limit the
amount of traffic loss during a planned shutdown. This document
expresses requirements for such a solution. This document is not
an Internet Standards Track specification; it is
published for informational purposes.
This document is a product of the Global Routing Operations Working Group of the IETF.
