Hi Pankaj

Kindly use "mls mpls tunnel-recir" command in 7600.

Hope after adding the command, you will receive end to end connectivity.

If you do not enable tunnel-MPLS recirculation, the IPv4 and IPv4-tunneled packets that have to be labeled (for example, the packets that are encapsulated with an MPLS header) will be corrupted when they are transmitted from the Cisco 7600 series router.

In data sheet of Sup 32, gre is supportingbut in real life scenario many of the providers are getting stucked when vrf is imposed in tunnel.

Hi shivlu ,

Without SIP/SPA

Re: Issue in 7600 when vrf forwrding over gre tunnel

Hi Pankaj

For this you require SIP-400 where in you need to bind the tunnel. Then it will come up. The behavior observed is that when the ip traffic comes from CPE in GRE and becomes a part of vrf, it doesn't work. So if you want to use MPLS over GRE use SIP 400.
