Static routes are routes that are manually configured by an administrator and are not learned from any routing protocols. Floating static routes are configured with a higher administrative distance than a primary route and are used as backup routes in case the primary route fails. Here are the two reasons why an engineer might configure a floating static route:

A. To enable fallback static routing when the dynamic routing protocol fails: When a dynamic routing protocol like OSPF or EIGRP is used, the router learns routes from its neighbors and uses this information to build its routing table. However, if the dynamic routing protocol fails or if the link to the neighbor goes down, the router will not be able to learn new routes or update its routing table. In such a situation, a floating static route can be configured with a higher administrative distance to act as a backup route for the network. If the dynamic route fails, the router will use the floating static route as a fallback route to continue routing traffic.

C. To automatically route traffic on a secondary path when the primary path goes down: A floating static route can also be used to automatically route traffic on a secondary path when the primary path goes down. This is achieved by configuring the floating static route with a higher administrative distance than the primary route. If the primary route fails, the router will use the floating static route as the backup route to route traffic on the secondary path.

To summarize, a floating static route can be used as a backup route when the primary route fails or to automatically route traffic on a secondary path when the primary path goes down.
