Usage scenario 3
A company has four offices, office A through office D, which are connected with one another through
networks. It is required to backup the forwarding of service data from office A to office C.
Assume that the routers are reachable to each other after being configured with IS-IS or OSPF and are
properly configured with basic MPLS and MPLS TE capabilities, CR-LSP backup is configured at Router A,
as shown in
Figure 71 :
Figure 71 Usage scenario 3
In this scenario, you can create two tunnels through a dynamic signaling protocol: tunnel A (Router A —>
Router B —> Router C) and tunnel B Router A —> Router D —> Router C. Thus you can configure tunnel
B as the CR-LSP backup tunnel of tunnel A. Then you should then introduce traffic to tunnel A.
NOTE:
You cannot configure CR-LSP backup for MPLS TE tunnels configured using the static CR-LSP protocol.
