Correct.

> 2) In the Hello Message, if the Transport Address TLV is not present, when opening the LDP session TCP connection, we should use the IPv4 source address for the UDP packet or the LDP Identifier's IP addr for the LDP PDU?

Source address of the LDP hello packet.

When interfaces go up or down. (think link failure or a newly
provisioned interface).
