Route Recursion
The nexthops of some static routes configured with nexthops may not be directly connected. To forward
the packets, the outgoing interface to reach the nexthop must be available. Route recursion is used to
find the outgoing interface based on the nexthop information of the route.
Sharing of Routing Information
As different routing protocols use different routing algorithms to calculate routes, they may find different
routes. In a large network with multiple routing protocols, it is required for routing protocols to share their
routing information. Each routing protocol has its own route redistribution mechanism. For detailed
information, refer to the description about route redistribution in each routing protocol.
