This document describes a mechanism for BGP that would help minimize
the negative effects on routing caused by BGP restart. An End-of-RIB
marker is specified and can be used to convey routing convergence
information. A new BGP capability, termed "Graceful Restart
Capability", is defined that would allow a BGP speaker to express its
ability to preserve its forwarding state during BGP restart, as well
as to convey its intention of generating the End-of-RIB marker upon
the completion of its initial routing update. Finally, procedures
are outlined for temporarily retaining routing information across a
TCP session termination/re-establishment.
The mechanisms described in this document are applicable to all
routers, both those with the ability to preserve the forwarding state
during BGP restart and those without (although the latter need to
implement only a subset of the mechanisms described in this
document).
