LAN Internet Routing Table
The purpose of the LAN internet routing table (Table 3-3) is to list all
possible networks that can be reached from each gateway node on a
LAN, such as NET1 in the example.
As shown on the internetwork map, NET1 includes a neighbor gateway
node B. In the IP Node Address column of the LAN internet routing
table, the node portion of the gateway node’s IP address is listed. The
LAN internet routing table shows that NET1 nodes using node B as a
gateway can reach NET2 in one hop, NET5 in two hops, and NET3 in
three hops. Node B is also designated as a default gateway.
