Configure IPv6 Floating Route
Configuration Condition
None
Configure an IPv6 Floating Route
IPv6 floating static route indicates there are multiple routes to the same destination network. The output interfaces or gateway addresses of the routes are different, and the priorities of the routes are also different. The route with the higher priority becomes the primary route while the route with the lower priority becomes the floating route. In the routing table, only the primary route is visible. The floating table appears in the routing table only when the primary route becomes invalid. Therefore, the floating route is usually used as a backup route.

In configuring the priorities of the routes, the smaller the distance value is, the higher the priority is.
