A mechanism for BGP that helps minimize the negative effects on
routing caused by BGP restart has already been developed and is
described in a separate document ("Graceful Restart Mechanism for
BGP").  This document extends this mechanism to minimize the
negative effects on MPLS forwarding caused by the Label Switching
Router's (LSR's) control plane restart, and specifically by the
restart of its BGP component when BGP is used to carry MPLS labels
and the LSR is capable of preserving the MPLS forwarding state across
the restart.

The mechanism described in this document is agnostic with respect to
the types of the addresses carried in the BGP Network Layer
Reachability Information (NLRI) field.  As such, it works in
conjunction with any of the address families that could be carried
in BGP (e.g., IPv4, IPv6, etc.).  [STANDARDS TRACK]
