Hi, I'm exploring redundancy possibilities for a router hand off without a dynamic routing protocol. It's ugly and I'm not going to explain all the details here, but I basically have this configuration on a router:
interface Gi1/1 backup interface Gi1/2 ip address 192.168.1.1 255.255.255.252 interface Gi1/2 ip address 192.168.1.1 255.255.255.252 If interface Gi1/1 goes down will the router send a gratuitous ARP when interface Gi1/2 comes up? I seem to remember that it's default IOS behaviour to always send a gratuitous ARP when an interface first comes up. I don't have test hardware to hand and I can't simulate this in GNS because ethernet interfaces are permanently up in dynamips.
