Hi Robert, I agree with Chris in this case, with MPLS, what customer sees is a low end very simple CPE router. As a service provider, we too don't want much complexity and control on customer end routers. Also, there could be cases, where cusotmer end router does not support FR, or tunnel or what ever. (As far as I know, GRE tunnel on Cisco is not compatible with other vendor routers). I wish there could be a way you can control the traffic on the physical interface of PE itself. Along with the command "ip vrf forwarding VPN1", some ACL, or route-map or some thing could have been provided. Regards, KK "Chris C.," <theguber@hotmail.com>: > Robert, > > Let me clarify a little.
