A cisco router with the default (ip proxy-arp) enabled on the interface will spend all its time doing arp/proxy-arp for the hosts and it will actually work believe it or not. You'll notice massive cpu utilization. People who do this tend to not have a lot of clue or notice when their cpu is spending all its time doing this... One should always turn proxy-arp off on your interfaces both internal and customer facing so they don't make your router bear the load because they can not configure their devices logically. - Jared > > So then what do you call a connected route (for an ethernet interface on a > > router)?
