Prestige P645 ADSL Internet Access Router
Although there are four frame types available on the Ethernet, you should configure as few frame types as
possible on your NetWare server and use automatic frame detection on the clients to simplify management
and to reduce network overhead.

6.1.3 External Network Number

Each of the four logical networks (based on frame type) has its own external network number.

6.1.4 Internal Network Number

In addition to the external network numbers, each NetWare server has its own internal network number that
is a virtual network to which the server is attached. It is important to remember that every network number
must be unique for that entire internetwork, either internal or external.
