Requirements for the graceful shutdown of BGP sessions

Tue, 03/10/2009 - 16:46 by Pierre François • Categories:


The BGP protocol 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 up a
BGP session for maintenance purposes may still induce connectivity
losses during the BGP convergence. This is no more satisfactory 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.
