By connecting AppleTalk networks to other AppleTalk networks, the AppleTalk router creates an internetwork. You can use an AppleTalk router to do the following:
When the AppleTalk router is connected to two or more network segments, it receives packets from a node on one network segment and forwards them to the destination node on another network segment.
Each network on an internetwork is assigned a unique identifier, specifically an address made up of a number or range of numbers. Every AppleTalk packet sent out on the internetwork includes the network number of its destination. The router is a forwarding device. It receives packets on one of its networks, consults the destination network number, and forwards the packet to the proper network.
An AppleTalk router forwards AppleTalk packets between the Macintosh computers and servers on the two networks, as shown in Figure 2.
