Chapter 4 - AppleTalk Routing & Bridging 85
Phase 1 Net #
For an AppleTalk Phase 1 Bridge Group which you set to Seed Phase 1, you
must provide a network number. This is a decimal number that uniquely iden-
tifies the network segment(s) which are part of the group, for Phase 1. Accept-
able 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.
Phase 1 Zone
For an AppleTalk Phase 1 Bridge Group 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(s). 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 Bridge Group. 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.
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.
AppleTalk Phase 2 Configuration
AppleTalk Phase 2 is an updated version of the AppleTalk protocol which
allows for more than 256 nodes on an Ethernet segment, and reduces the over-
head required by AppleTalk RTMP (Routing Table Maintenance Protocol).
AppleTalk Phase 2 should be used for all new installations.
