Symptoms: The routers acts as though local proxy-arp is configured and does a proxy-arp for the
systems in the same subnet.
Conditions: This issue occurs when the router receives ARP request on an interface when the
interface is not fully initialized. The connected routes are not added in the routing table causing the
proxy-arp to reply and thus the wrong ARP is entered.
Workaround: Execute a shutdown followed by a no shutdown on the routers.
