Hi I'm having a problem establishing a stable GRE tunnel and was wondering if anyone could help?
Both Routers are 7200s. RouterA is running IOS rev 12.3(4r) and RouterB is running IOS rev: 12.2(5d). Both sides of the tunnel show as UP/UP until I enable keepalives on RouterA (RouterB doesn't seem to support them), then RouterA predictably shows the tunnel as UP/DOWN.
I can ping the local interface on RouterA, but RouterB can't seem to ping it's local interface.
I've changed the IPs, but the config on the tunnels is attached (RouterA.txt & RouterB.txt).
Running a debug on the tunnel produces nothing useable. IP ICMP Debug just shows RouterB encapsulating messages, but nothing is returned.
Setting tunnel mode to be ip-ip allows RouterB to ping it's local interface and allows us to ping down the tunnel.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
