   This document specifies a fast reroute framework for protecting IP/
   MPLS services and MPLS transport tunnels against egress node and
   egress link failures.  For each type of egress failure, it defines
   the roles of point of local repair (PLR), protector, and backup
   egress router, and the procedures of establishing a bypass tunnel
   from a PLR to a protector.  It describes the behaviors of these
   routers in handling an egress failure, including local repair on the
   PLR, and context based forwarding on the protector.  The framework
   can be used to develop egress protection mechanisms to reduce traffic
   loss before global repair reacts to an egress failure and control
   plane protocols converge on the topology changes due to the egress
