I'm having a problem with our 6509 switch. We have had RIP enabled for a while and we'd like to disable it on this switch because we felt that it was not being used. However when RIP is disabled, after a short period of time, it appears that the 6509 loses its routes. A 'sh ip route' command shows that the route for the subnetwork I'm trying to reach is entered in, in fact it's a local interface in the 6509 so it doesn't even need a static route, it shows connected. However clients on that subnetwork can receive data, but they cannot send any data.
I have noticed that re-enabling RIP fixes this problem almost immediately. Additionally, if I leave RIP disabled, and go to a client machine, and do a 'tracert' into a PC on the network that the switch is on, communications will resume working properly.
I've had a Cisco Engineer look at the config on the switch and he says that it looks to be correct. Does anyone have any ideas what might be causing this scenario? Thanks
