Also known as: backup static route
Quick Definition
A backup static route with a higher AD than the primary dynamic route, installed only if the primary fails.
A floating static route is a static route configured with a manually increased Administrative Distance (higher than the primary routing protocol). In normal operation, the dynamic route has a lower AD and the floating static sits inactive in the configuration. If the dynamic route disappears (link failure, protocol issue), the static route 'floats' into the routing table as a backup. This provides a simple failover mechanism without complex routing protocol configuration.
ip route 192.168.2.0 255.255.255.0 10.0.0.3 200 ! AD of 200 — higher than OSPF (110)
The floating static route must have an AD higher than the primary routing protocol. If OSPF (AD 110) is the primary, the floating static should have AD > 110, e.g., 200. If the static has AD 1 (default), it would always win over OSPF.

Floating Static Route falls under the Routing domain of the 200-301 exam. Understanding it in context with related terms like static-route and administrative-distance is essential for answering scenario-based questions correctly.
