I heard the LDP session establishment process involves a lot of 'hello-ing' and 'goodbye-ing' before the actual session starts.

Option A is definitely wrong. The session is established before any keepalive messages are exchanged.

Hmm, option D is interesting. I didn't know the party with the larger transmission address takes the active role. That's good to know.

I'm not sure about option B. Doesn't LDP use unicast addresses for the Hello messages, not multicast?

User 3: So, the correct option must be A) When both parties receive a keepalive message from the peer, the LDP session is successfully established, right?
