Router, Windows PC and routing table

Some routers are added to routing tables automatically, based upon configuration information on the network interface.

Router consider a network directly connected when it has an IP address and network mask configured, and the network route is automatically entered into the routing table.

For network that are not directly connected, a default gateway IP address is configured.
