Cisco Interview Question & Answer
What is a “floating static” route?
By default, static routes have an AD of one, which gives them precedence over routes from dynamic routing protocols. When you increase the administrative distance to a value greater than that of a dynamic routing protocol, the static route can be a safety net in the event that dynamic routing fails. For example, (IGRP) have a default AD of 100. I
This kind of static route is called "floating" static. It is installed in the routing table only when the preferred route disappears. For example, ip route 172.31.10.0 255.255.255.0 10.10.10.2 101.
Observe the following static route:?
ip route 192.168.1.0 255.255.255.0 Gig1/1
What is an advantage of referencing interface Gig1/1 instead of a next-hop?
What is a disadvantage.

the route is inserted into the routing table only when the broadcast interface is up. This configuration is not recommended because when the next hop of a static route points to an interface, the router considers each of the hosts within the range of the route to be directly connected through that interface.
