We have two Nortel 7480's in the core to terminate our stores on. We have an issue on one whereby you are unable to route through it to a range of 10.9.x.x even though the route is present in the fwd database and the route table. If you try and ping or trace route to the range you get stopped at the wan address of the 7480. If a store hangs off the other 7480 it works correctly swing it across and it fails. We have locked and unlocked the vr but still with no success. Any ideas ?
