Description

Enables you to configure the IP address used to specify the TCP session for the LDP session. Routers must first establish a TCP session between one another before they can establish an LDP session. The TCP session enables the routers to exchange the label advertisements needed for the LDP session. To establish the TCP session, each router must learn the other router's transport address. The transport address is an IP address used to identify the TCP session over which the LDP session will run.

Default

router-id

Options

address

Use the specified IP address as the transport address for the LDP session.

interface

Use the first IP address on the interface as the transport address for any LDP sessions to neighbors that can be reached over that interface. You cannot specify the interface option when there are multiple parallel links to the same LDP neighbor, because the LDP specification requires that the same transport address be advertised on all interfaces to the same neighbor. If LDP detects multiple parallel links to the same neighbor, it disables interfaces to that neighbor one by one until the condition is cleared, either by disconnecting the neighbor on an interface or by specifying the router-id option.

router-id

Use router identifier as the transport address. Unless otherwise configured, the router identifier is the loopback address.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced before Junos OS Release 7.4.

address option introduced in Junos OS Release 19.1R1 for all platforms.
