Auto-Seed means the router will listen for an AppleTalk Phase 1 
network number being set by another router on the segment connected to 
this interface and use this number if it exists. If it doesn’t discover a 
number in use, the router will auto-generate a valid number using its 
routing tables.

For Ethernet interfaces which you set to Seed Phase 1, you must provide a 
network number. This is a decimal number that uniquely identifies the 
network segment connected to this interface, for Phase 1. Acceptable values 
range from 1 to 65,279.

v Note:  Accidental selection of an AppleTalk network number which is 
already in use on another network segment may cause hard-to-diagnose 
problems. You should carefully track which AppleTalk network numbers are 
in use, and where they are used.

For Ethernet interfaces which you set to Seed Phase 1, you must provide a 
zone name. This is the name associated with the network number entered 
above. Zone names may be up to 32 characters in length.

Typically a name is chosen which has some significance to the physical loca-
tion or the corporate purpose of the network segment. An example would be 
“Accounting Department.”

This name will appear in the Chooser program of computers which support 
AppleTalk.

You can provide a suggestion for the node number the router should use on 
this AppleTalk Phase 1 interface. The router will try to claim this number 
when it is powered up or restarted.

v Note:  The AppleTalk protocol allows network nodes to dynamically claim 
node numbers when they start up. Assigning known AppleTalk node numbers 
to router interfaces can make it easier to diagnose network problems using a 
network packet monitor.

The parameters required for NBP Filtering are contained in a configuration 
screen brought up by the “Filtering” button. This screen is discussed later in 
this chapter.
