Cisco® CCNA Exam Cram Notes : Floating static route

III. Routing Technologies

4. Floating static route

A Floating static route is a route that has a higher administrative distance than the current route in a routing table. The routes that have a lower administrative distance number will be the ones installed into the routing table whereas higher AD numbers will not. Static floating route is static route like any other but with added administrative distance in the configuration

The Administrative Distance of a static route can be changed to form a floating static route, which will only be used if there are no other routes with a lesser AD in the routing table. A floating static route is often used as a backup route to a dynamic routing protocol. To create a floating static route, we need to use the distance option at the end of the ip route command. We really just need to set an AD for the static route.
