I am curious about a simple thing :)
Lets say we got two routers connected through a hub. Attached is a simple topology. Say Router 1 has two static route entries. First pointing out to Router 2 and second to router 3. when router 2 gets disconnected. Does router 1 fails over to the second router even if its interface does not GO DOWN ? Does it check the availability of the next hop through ARP table entry for the next hop IP address ?
