entire internet does.
A seed router initializes the internet with AppleTalk configuration
information, including network numbers and zone names. The seed router
broadcasts this information so that nonseed routers can learn it. You can
designate a seed router through the Administration Console.
A nonseed router listens for a seed router and then takes the configuration
information from the first seed router it detects. After a nonseed router
obtains the configuration information, it can participate in the network as if
it were a seed router as well.
AppleTalk protocols work together to ensure the seamless flow of
information throughout the AppleTalk internet. Figure 7-2 shows a
simplified view of AppleTalk protocols and their relationship to the OSI
reference model. Together, these protocols provide the following services:
Physical Connectivity
End-to-End Services
Reliable Data Delivery
