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?

A. 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.

B. 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.

C. Configure the new PE router with the mpls ldp session protection command and on neighboring routers that connect to this new PE router.

D. Configure the new PE router with the mpls ldp session protection command on interfaces with directly connected neighbors.

A. Configure EIGRP as the routing protocol using stub areas only.

B. Enable MPLS LDP sync delay timers.

C. Configure OSPF or IS-IS as the routing protocol.

D. Disable the MPLS LDP IGP sync holddown.
