Consider the following command:
ip route 192.168.10.0 255.255.255.0 10.10.10.2 5
Which route would have to go down in order for this static route to appear in the routing table?
- a default route
- a static route to the 192.168.10.0/24 network
- an OSPF-learned route to the 192.168.10.0/24 network
- an EIGRP-learned route to the 192.168.10.0/24 network
Answers Explanation & Hints: The administrative distance of 5 added to the end of the static route creates a floating static situation for a static route that goes down. Static routes have a default administrative distance of 1. This route that has an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. The administrative distance of 5 added to the end of the static route configuration creates a floating static route that will be placed in the routing table when the primary route to the same destination network goes down. By default, a static route to the 192.168.10.0/24 network has an administrative distance of 1. Therefore, the floating route with an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. Because the floating route has an administrative distance of 5, the route is preferred to an OSPF-learned route (with the administrative distance of 110) or an EIGRP-learned route (with the administrative distance of 110) to the same destination network.
