Point-to-Point Network Table
Refer to the Point-to-Point network map to fill in the Point-to-Point
network table (Table 3-4). We have completed the first column by listing
the names of all the nodes on NET2. Each node is assigned an IP
address that is unique within the network. Only the node portions of
the IP addresses are listed because we have listed the IP network
address at the top of the table. In the third column of Table 3-4, note
that node G is a central administrative node. In the fourth column,
nodes B and G are indicated as gateway nodes. For the Implementation
Priority column, the nodes are ranked in the recommended order of
configuration.
Point-to-Point Internet Routing Table
The purpose of the Point-to-Point internet routing table (Table 3-5) is to
list all possible networks that can be reached from each gateway node
on a Point-to-Point network, which is NET2 in the example. (Note that
there may be more than one route to a network.)
As shown on the internetwork map, NET2 includes two gateway nodes,
B and G. In the IP Node Address column of the Point-to-Point internet
routing table, the node portion of each gateway node’s IP address is
listed. The Point-to-Point internet routing table indicates that NET2
nodes using node B as a gateway can reach NET1 in one hop, NET4 in
two hops, and so on.
