Question
Click on the exhibit button below. Assume the following:
- Each router's OSPF interfaces are in the areas shown.
- Bidirectional LDP-over-RSVP tunnels extend from routers R1 to R3 and
back over the path R1-R4-R5-R3.
- You enable fast reroute facility bypass on the R5-R3 RSVP LSP.
- Router R5 acts as a PLR, protecting the R5-R3 link by building a
bypass tunnel through router R2. You build a layer 2 VPN on routers R1 and R3, using the LDP-over-RSVP tunnels. What MPLS configuration step must you complete on router R2 for it to protect the end-to-end service?
