(Optional) Configuring an LDP Transport Address

Before establishing an LDP session, two LSRs confirm each other's LDP transport address and set up a TCP connection.

Context

An LDP transport address is used to set up a TCP connection between peers. A route to the LDP transport address must be reachable on each peer. An LSR ID, which is the loopback interface address, serves as the LDP transport address.

The LDP sessions over multiple links between two LSRs can be established using the same pair of transport addresses.
A change in an LDP transport address will terminate the associated LDP session. Exercise caution when configuring an LDP transport address.

The default LDP transport address is recommended.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The view of the interface on which an LDP session is to be established is displayed.
Run mpls ldp transport-address { interface-type interface-number | interface }
The IP address of a specified interface is configured as an LDP transport address.
- interface-type interface-number: LDP uses the IP address of this specified interface as the transport address.
- interface: LDP uses the IP address of an existing interface as the transport address.
Run commit
The configuration is committed.
