You are tasked to enable LDP on many of the interfaces on the Cisco CRS-3 router, and because
there are many interfaces that need to have LDP enabled, you mistakenly did not enable LDP on all
the required interfaces. To prevent this issue from happening again in the future, what could you do
the next time you need to enable LDP on many interfaces?

A.
use the mpls ldp auto-config command under the IGP routing process

B.
use the mpls ldp sync command under the IGP routing process

C.
use the interface all command under the MPLS LDP process

D.
use the discovery command under the MPLS LDP process
