recovers, the route selection process is performed again and the main route is selected again to forward

packets.

Route recursion

The next hops of static routes configured with next hops may not be directly connected. The outgoing
interface to reach the next hop must be available. Route recursion is used to find the outgoing interface

based on the next hop information of the route.

Route redistribution

Different routing protocols running on a network learn route information from each other through route

redistribution. Each routing protocol can redistribute routes from other protocols, direct routes, and static

routes. For more information, see relevant protocols in this configuration guide.
