Network architecture
The network architecture in the figure is used in this example.
Routing tables for IP host nodes
Not only IP router nodes but also IP host nodes have Routing Tables. The Routing
Table is used for every IP packet generated by this IP host. As can be seen in the table
below, each node has two routing entries. These two routing entries will be discussed
separately.
The routing tables for nodes I1, I2, I3, I4, and I5, see the previous figure:
