I'm looking for a way to configure a router or CatOS switch to "poison" an IP address. By this, I mean that if a device with the poisoned address was connected to the LAN, it would not work (perhaps by detecting a duplicate address and failing to start, for those devices that check with a gratuituous arp). One thought was to create static arp table entries with bogus mac addresses. Would this work? Any other suggestions?
What about a similar poisoning of a MAC address? Would a static CAM entry prevent the connection of a device with a prohibited MAC address? Any other suggestions?
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
