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 failure.
This document is a product of the Multiprotocol Label Switching Working Group
of the IETF.
This is now a Proposed Standard.
