Hi,
We are having a strange issue after deploying 7604 Router in our Network. When we connect our customer to 7604 Router their GRE tunnel never got up. But if we use 7200 router then it is working fine. Here is topology diagram:
CE1==>PE1-SWITCH==>PE1-ROUTER===MPLS CORE NETWORK=====PE2-ROUTER===>PE2-SWITCH====>CE2
Problem is at PE1-ROUTER where 7604 is in use. Tunnel showing UP/Down at CE1 and UP/UP at CE2.

Hello,
can you post the config of the 7604 ? Which IOS are you running ?

Sorry I missed that you already posted the 'sh ver'. I checked for bugs: do you have any QoS on your tunnel ?
Either way, seeing the configs of both the 7600 and the 7200 could provide a clue.
