MPLS Interface Tasks

To configure MPLS on the interface:

1. Enable MPLS on the interface.

   host1(config-if)#mpls

   or

   host1(config-if)#no mpls disable

2. (Optional) Configure the interface label space with the VPI and VCI ranges.

   host1(config-if)#mpls atm vpi range 10 200

   host1(config-if)#mpls atm vci range 33 4000

   Only ATM AAL5 interfaces support the interface label space. For MPLS interfaces using the interface label space, you must configure the both the VPI and VCI range. If you do not, the interface will remain operationally down.

3. (Optional) Specify an interface for signaling for an MPLS major interface in the interface label space.

   host1(config-if)#mpls signaling-interface atm 4/0.5
