MPLS fast reroute using one-to-one backup
The Multi-Service IronWare software supports MPLS Fast Reroute to provide 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.
Finding a detour at a PLR
Figure 13 illustrates how the algorithm works to determine the detour at each PLR.
NOTE
Although the example illustrates this method from only the Ingress router point-of-view, the same
functionality operates on each PLR in the protected path.
