MPLS fast reroute using one-to-one backup

MPLS Fast Reroute provides the ability for an LSP to route traffic around a failed node by using a detour route as described in RFC 4090. By using the one-to-one backup method, each LSR except the egress router is identified as a Point of Local Repair (PLR). Each PLR tries to initiate a detour LSP to provide a backup route for the protected path. This detour LSP is used to reroute traffic locally on the detour path in the event of a failure on the protected path. The detour path is computed to exclude the protected link or protected node.
