Hi,
I'm trying to  help a friend to establish an mpls vpn
in the following topology:
 
 
 
 
CMTS( cisco ubr 10000 ) PE1 ----cisco GSR----cisco 7200 PE2
 
Bgp is up between the PE routers, but there is no vrf ping between the vrf interfaces in the PE routers.
The source addresses of the bgp in the cmts is the interface connected  to the gsr, and in the 7200 the source of the bgp is just some interface.
When i'm changing the source of the bgp in the cmts to the loopback interface then everrything works fine.
any ideas why this happens.
