The Border Gateway Protocol(BGP) is heavily used in Service Provider
networks both for Internet and BGP/MPLS VPN services. For resiliency
purposes, redundant routers and BGP sessions can be deployed to
reduce the consequences of an AS Border Router 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 not
satisfactory any more for new applications (e.g. voice over IP, on
line 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.
