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?

• A.Configure LDP-over-RSVP support on router R2.
• B.Enable LDP on the R2-R5 interface.
• C.Enable MPLS and RSVP on the router R2 network interfaces.
• D.Enable LDP on the R2-R5 and R2-R3 interfaces.
• E.Configure T-LDP sessions between routers R2 and R5 and R3.

An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database.
What action does the router take?

• A.The link-state information is regarded as old and nothing is done.
• B.The link-state information already in the database is overwritten and the age is reset.
• C.A link-state request is performed to increase the sequence number.
• D.The link-state information is not populated in the database and an acknowledgement is sent.
• E.The link-state information is not populated in the database, but is forwarded to all neighbors.
