[c-nsp] ASR9K MPLS basics

[Ghassan.khalil]

I am planning to install an ASR9K as a PE router in my network.
The ASR will be connected to another 2 PE routers 7613.
Can anyone provide me with essential configuration for MPLS on the ASR as I am new to the IOS XR. And I am aiming to apply L3MPLS and VPLS which seems really different than dealing with a 7613 router knowing that the other 2 PEs are running these service pretty fine.

As a first step I need to make sure that  the interfaces are MPLS enabled on the ASR and MPBGP neighboring is running.
Some might advise to google that :) but i hope I can minimize my searches with your help guys.

Regards,
Ghassan
