I agree with Dwight, the correct answer is B because a full mesh of RSVP-TE LSPs is not required to protect the LDP-over-RSVP tunnel.

But D is required to protect the tunnel, not the one that is NOT required.

I'm going with C. ABR-1 doesn't need to establish T-LDP sessions to all ABRs in area 0 to protect the LDP-over-RSVP tunnel.

Haha, who needs a full mesh of RSVP-TE LSPs when you can just use a tangled web of LDP sessions? Option B all the way!

I think we should stick with option B. It's the easiest solution to protect the LDP-over-RSVP tunnel.

True, fast reroute does sound important. Maybe we should reconsider option D as well.

But what about fast reroute on all RSVP-TE LSPs? Wouldn't that be important for protection?

I agree, a full mesh of RSVP-TE LSPs sounds like a headache. Option B seems like the simpler choice.
