I have been playing with MPLS on my 2500's and I came across this -

There are lots of little explanations and examples in there. Hope it helps!!

Here's our basic config for the VRF - I can't tell you what every single command does, but this might help. Also, the route-reflector isn't required - in this case due to our specific setup.

ip vrf test
rd 100:99
route-target export 100:99
route-target import 100:99

address-family vpnv4
neighbor BGP.Peer.IP.Addr activate
neighbor BGP.Peer.IP.Addr route-reflector-client
neighbor BGP.Peer.IP.Addr send-community both
neighbor BGP.Peer.IP.Addr activate
neighbor BGP.Peer.IP.Addr route-reflector-client
neighbor BGP.Peer.IP.Addr send-community both
neighbor BGP.Peer.IP.Addr activate
neighbor BGP.Peer.IP.Addr route-reflector-client
neighbor BGP.Peer.IP.Addr send-community both
neighbor BGP.Peer.IP.Addr activate
neighbor BGP.Peer.IP.Addr route-reflector-client
neighbor BGP.Peer.IP.Addr send-community both

We use it extensively in our network though it still has some bugs. We're testing 12.4.9(T1) now to see what has been fixed or broken.
