Dumb question time.
I have 5 routers. Under Router OSPF config mode, I type "router-id x.x.x.x". On 4 of the routers this is accepted. On one of them it isn't.
The router that it isn't accepted on is a 2503 running an old IOS - 11.3(6).
Is it not accepting the command because the old software doesn't take it, or is it something else?
Reckon it's time I upgraded it!
