Questions # 24:

How does LDP operate in an MPLS network?

Options:
A.

When topology changes occur such as a router failure, LDP generates peer discovery messages that terminate the LDP season to propagate an LSP change.

C.

Peer routers establish the LDP session, and the LDP neighbors maintain and terminate the session by exchanging messages

D.

LDP notification messages allow LERs to exchange label information to determine the next hops within a particular LSP.
