I setup a GRE tunnel between two cisco 2621 routers. They are both running IOS c2600-advsecurityk9-mz.123-6c.bin. When I do a show ip int brief they both show up/up. I can ping the tunnel address the router is on but not the far end. This is true for both routers. I can also ping both the source and dest. of the tunnel from both routers. So I know that there shouldn't be any recurvise routing problems. I have looked all over the cisco site trying to find some troubleshooting information but, I don't see anything that applies. Any help would be appreciated.
Here is a copy of my configs:
