This draft describes operational procedures aimed at reducing the
amount of traffic lost during planned maintenances of routers,
involving the shutdown of BGP peering sessions.

Requirements for the graceful shutdown of BGP sessions

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).
