MPLS Interface Configuration Tasks

These tasks are performed at the major interface over which you want to run MPLS.
Creating or accessing an interface places the CLI in Interface Configuration mode.
You can then configure MPLS options on that interface. The following sequence is
arbitrary; you can perform these tasks in any order.
NOTE: Loop detection is always enabled in the JUNOSe MPLS implementation.
Your choice of label distribution protocol determines whether the LDP or RSVP-TE
interface configuration tasks are appropriate for your network design.
MPLS interface configuration tasks include the following sets of tasks:

Enable MPLS on the interface.

or
host1(config-if)#no mpls disable
(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.
(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
