A network engineer is configuring a newly installed PE router at the regional gateway location. The new PE router must use MPLS core routing protocols with the existing P router, and LDP sessions between the two routers must be protected to provide faster MPLS convergence. Which configuration must the engineer perform on the network so that LDP sessions are established?

A. Enable RSVP-TE FRR on the LDP interface to protect the LDP session between routers.

B. Enable communication over TCP port 646 T-LDP hello messages.

C. Set the LDP session protection timer on each router to the same value.
