Problem:- If you are using cisco 7600 as a PE router and configuring Vrf forwarding over GRE then you will be unable to ping CE side GRE tunnel ip from Remote PE.
Solution:-put a global command on Cisco 7600 PE "mls mpls tunnel-recir".
Cause:-Packet gets corrupted when it is received from CE back to PE, so conversion of IPv4 to MPLS doesn't happen.
