Cisco CCNA 200-301 Practice Question

To configure a backup static route, the administrator should set a higher administrative distance on the static route than that of the primary route. This creates a floating static route that the router will only use if the primary route becomes unavailable. Configuring a static route with the same or lower administrative distance could cause the router to prefer the backup route over the primary. Implementing a dynamic routing protocol is unnecessary for a floating static route.
