In addition, based on whether the network where the destination locates is directly
connected to the router, routes fall into:
Direct route
The router is directly connected to the network where the destination locates.
Indirect route
The router is not directly connected to the network where the destination locates.
In order to prevent the routing table from being too huge, you can set a default route.
All the packets that fail to find the suitable entry will be forwarded through this default
route.

network address. The router R8 is connected with three networks, so it has three IP
addresses and three physical ports, and its routing table is shown in

Routers support configuring static routes and a series of dynamic route protocols,
such as RIP, OSPF, IS-IS and BGP. In addition, routes in work can automatically
obtain some directly connected routes based on interface state and user
configuration.

2.2 Routing Management Policy

The router supports the configuration of a series of dynamic routing protocols such as
RIP, OSPF, Integrated IS-IS and BGP, as well as the static routes. The static routes
configured by the user are managed together with the dynamic routes discovered by
the routing protocol in the router. The static routes and the routes learned or
configured by different routing protocols can also be shared with each other.
