View

Interface view, MPLS LDP remote peer view

Default Level

1: Monitor level

Parameters

ip-address: IP address for LDP to use as the TCP transport address.

interface: Specifies that LDP use the IP address of the current interface as the TCP transport address. This keyword is available only in interface view.

Description

Use the mpls ldp transport-address command to configure an LDP transport address.

Use the undo mpls ldp transport-address command to restore the default.

By default, a transport address takes the value of the MPLS LSR ID.

In interface view, you configure the link Hello transport address; in MPLS LDP remote peer view, you configure the targeted Hello transport address.

Examples

# On interface VLAN-interface 1, configure the link Hello transport address as the IP address of the current interface.
