| Communication Between Networks |
| Since the main purpose of the internetwork map is to show how |
| networks are connected, gateway nodes are the only nodes you should |
| label on the internetwork map. All other nodes and their networks can |
| be represented by drawing sketches of the networks, as shown in Figure |
| |
| NET2, node A is a full gateway that belongs to NET1 and NET4, and |
| node C is a full gateway that belongs to NET1 and NET6. Nodes G and |
| H are gateway halves that belong to NET2 and NET5, respectively. |
| Single letters are used to represent node names in this example. Actual |
NOTE | |
| node names must be in an accepted format. They may be either in the |
| form nodename.domain.organization or they may be in a valid |
| domain name format. |
Network Boundaries
Once you have drawn your gateway nodes and routers, you have established network boundaries. Consider the example and look at Figure
