FW: [c-nsp] One BGP-L2VPN question

Hi,

   So BGP can be used as the routing protocol between PE-PE ? 

  Shall I have to use MP-BGP in this case.  

  One of my PE is Cisco 7206. When I am using core BGP the ip routing
table is updated
with the route but the mpls forwarding table is not updated and thus
the PW is not coming
up.

  Do I have to perform any configuration on the CISCO or shall I have
to use MP-BGP?

Thanks
Arnab
