A network administrator uses the command ip route 172.18.0.0 255.255.0.0 S0/0/1 to configure a floating static route on a router. That route will function as a backup route to reach the EIGRP learned network 172.18.0.0/16. After this configuration, the EIGRP route is removed from the routing table even though EIGRP is still functioning properly. Why is the static route not functioning as intended?

A network administrator uses the command ip route 172.18.0.0 255.255.0.0 S0/0/1 to configure a floating static route on a router. That route will function as a backup route to reach the EIGRP learned network 172.18.0.0/16. After this configuration, the EIGRP route is removed from the routing table even though EIGRP is still functioning properly. Why is the static route not functioning as intended?

• The network mask is incorrectly configured.
• The next hop neighbor IP address is not configured.
• The destination network is incorrectly configured.
• The administrative distance value is not high enough on the static route.

Explanation: A floating static route requires an administrative distance greater than that of the dynamic routing protocol in order to be used as a backup route. In this problem an administrative distance greater than 90 would have to be added to the static route: ip route 172.18.0.0 255.255.0.0 S0/0/1 100.
