Chapter 4 - AppleTalk Routing & Bridging

73

 

 

Auto-Seedmeans 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.

Phase 1 Net #

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.

ϖNote: 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.

Phase 1 Zone

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.

Phase 1 Node

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.

ϖNote: 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.

NBP Lookup Filters (Filtering)

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.
