1. A. Configure a queue with sufficient memory to buffer excess packets.
2. B. Configure the token values in bytes.
3. C. Implement packet remarking for excess traffic.
4. D. Implement a scheduling function to handle delayed packets.

A new PE router is configured to run OSPF as an IGP with LDP on all interfaces. The engineer is trying to prevent black holes after convergence when the PERSON device loses an LDP session with other PE routers. Which action must the engineer take to implement LDP session protection on a new PE router?

1. A. Configure the mpls ldp session protection and mpls label protocol ldp commands on the interfaces on the new PE router that connect to the CENTER routers.
2. B. Configure the mpls ldp discovery targeted-hello accept and mpls ldp session protection commands on the interfaces on the new PE router that connect to the CE routers.
3. C. Configure the new PE router with the mpls ldp session protection command and on neighboring routersthat connect to this new PE router.
4. D. Configure the new PE router with the mpls ldp session protection command on interfaces with directly connected neighbors.

Correct Answer: C
