Outbound interface: Specifies the interface through which the IP packets are to
■
be forwarded.
IP address of the next hop: Specifies the address of the next router on the path.
■
If only the outbound interface is configured, its address will be the IP address of
the next hop.
Priority for the route. Routes to the same destination but having different
■
nexthops may have different priorities and be found by various routing
protocols or manually configured. The optimal route is the one with the highest
priority (with the smallest metric).
Routes can be divided into two categories by destination:
Subnet routes: The destination is a subnet.
■
Host routes: The destination is a host.
■
Based on whether the destination is directly connected to a given router, routes
can be divided into:
Direct routes: The destination is directly connected to the router.
■
Indirect routes: The destination is not directly connected to the router.
■
To prevent the routing table from getting too large, you can configure a default
route. All packets without matching entry in the routing table will be forwarded
through the default route.
In Figure 63, the IP address on each cloud represents the address of the network.
Router G resides in three networks and therefore has three IP addresses for its
three physical interfaces. Its routing table is shown on the right of the network
topology.
