configure mpls add vlan

configure mpls add {vlan} vlan_name

Description

Adds an MPLS interface to the specified VLAN.

Syntax Description

vlan_name Identifies the VLAN where the MPLS interface is added.

Default

VLANs are not configured with an MPLS interface.

Usage Guidelines

An MPLS interface must be configured on a VLAN in order to transmit or receive MPLS packets on that interface. By default, MPLS, LDP, and RSVP-TE are disabled for the MPLS interface. The specified VLAN should have an IP address configured and should have IP forwarding enabled. The MPLS interface on the VLAN does not become active until these two conditions are met. Also, if the IP address is unconfigured from the VLAN or IP forwarding is disabled for the VLAN, the MPLS interface goes down. The MPLS interface state is viewed using the show mpls interface command.

The VLAN must be operational for the MPLS interface to be up. This means that at least one port in the VLAN must be active or the VLAN must be enabled for loopback mode.

It is recommended that when you configure MPLS on an OSPF interface that can be used to reach a given destination, you should configure MPLS on all OSPF interfaces that can be used to reach that destination. (You should enable MPLS on all of the VLANs connected to the backbone network).

Example

The following example adds MPLS to the VLAN vlan_usa:

configure mpls add vlan vlan_usa
