MPLS enable on FE dot1q subinterfaces

[a.sanes]

Hi, i am implementing MPLS-VPN in a LAB environment. There is a cisco 7200 acting as a P router connected through FE subinterfaces (dot1q) to two different VLANs. Each VLAN has a PE router connected and also another router (not configured for MPLS) configured to perform NAT. There are two VPNS configured with sites at each PE and the communication works fine (intranet). But, i cant reach networks that are not inside the VRFs in each PE, for instance a loopback interface in one PE global configuration. The IGP is OSPF and the P router has knowledge of all of them. Do i have to have an special configuration in the FE subinterfaces so it can process the non labeled packets as well as the labeled, i just configured "ip tag switching"... thanks in advance for your comments!

Where do you try to reach the global addresses from?

Hi... I cant ping for instance from the P (core router) the IP interface of the FE on the NAT router which is connected to the LAN where the PE router and the P (PoP router) are connected as well- The P "core router" is connected to the P "PoP router" through ethernet and then the P "PoP router" connects to the NAT and PE routers via another VLAN. Also in the PE router i have connected clients with fixed IP public addresses that cant reach neither the Core P router or the internet. The P PoP router in its label forwarding table have an input an output label associated with the IP of the NAT router (but the NAT router is not configured for MPLS)...Thanks

When you say the IP of the NAT router, you mean the FE interface right? If so, this should be seen as a directly connected network on the P POP router. The P POP router should definitely not have an entry in the LFIB for a directly connected route.
