4.3.4. Floating Static Route

A floating static route has a higher AD than normal so it's only used if the primary route fails. This creates backup paths.

IPv4 Example:

! Primary route via OSPF (AD 110)
! Backup static route with AD 120
Router(config)# ip route 172.16.0.0 255.255.0.0 10.1.1.1 120

IPv6 Example:

Router(config)# ipv6 route 2001:DB8:2::/64 2001:DB8:1::1 130

Verification:

Router# show ip route static
Router# show ipv6 route static
Router# show ip route 172.16.0.0

⚠️ Exam Trap: If a static route's next-hop IP is unreachable (no route to it), the static route won't appear in the routing table. The route becomes active again when the next hop is reachable.
