Abstract:
   This document specifies a fast reroute framework for protecting IP/
   MPLS services and MPLS transport tunnels against egress node and
   egress link failures.  In this framework, the penultimate-hop router
   of an MPLS tunnel acts as the point of local repair (PLR) for egress
   node failure, and the egress router of the MPLS tunnel acts as the
   PLR for egress link failure.  Each of them pre-establishes a bypass
   tunnel to a protector.  Upon an egress node or link failure, the
   corresponding PLR performs local failure detection and local repair,
   by rerouting packets over the corresponding bypass tunnel.  The
   protector in turn performs context label switching or context IP
   forwarding to send the packets to the ultimate service
   destination(s).  This mechanism can be used to reduce traffic loss
   before global repair reacts to the failure and control plane
   protocols converge on the topology changes due to the failure.  The
   framework is applicable to all types of IP/MPLS services and MPLS
   tunnels.  Under the framework, service protocol extensions may be
   further specified to support service label distribution to the
   protector.
