LDP sessions: IP address configuration

To establish a TCP session between two devices, each device must learn the other device's transport address. The transport address is an IP address used to identify the TCP session over which the LDP session operates. Earlier, this transport address could only be the router ID or an interface address. This feature introduces the possibility to explicitly configure any IP address as the transport address for targeted LDP neighbors for Layer 2 circuit, MPLS, and VPLS adjacencies. This enables you to control the targeted-LDP sessions using the transport-address configuration.
