Deploying MPLS for Traffic
Engineering and Backbone
VPNs
by Eric Osborne and Zaheer Aziz
will give you config example and one Ranjeet Sudan will give you a general idea
hope this helps

>In order to make MPLS VPNs really work, there are neat little things you can do.... First, you (may) run a routing protocol with your clients on the edge routers. You set up VRFs (virtual routing/forwarding instance) in order to separate the routing tables into a per-VPN setup. That way you can have multiple clients that technically have overlapping IP ranges. (in this instance, "normal" IP routing would fail miserably)

>Between your edge routers, internally, you will run MBGP (multiprotocol bgp) and use some extended community attributes to push each VRF routing table separate from the rest. So ALL of your routers have the entire BGP community/subcommunity routing table, and know how to get any packets to the appropriate other members of the same VPN.

Otherwise, I would suggest talking to the Cisco SEs (or NSA folks, whoever your reps are), because they can give you better access to any internal documentation that will help spell everything out. They have samples, powerpoint presentations and everything to assist you!

The customer would prefer to run his own routing protocol between his sites, & how does a service provider provision this.
