connected to this interface, for Phase 2. Acceptable values vary from 1 to
65,279. The value on the left must be smaller than the value on the right.
Each individual number in the range will support up to 253 node addresses.
v Note: Accidental selection of an AppleTalk network number (or range of
numbers) 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 2 Zones
For an AppleTalk Phase 2 Bridge Group which you set to Seed Phase 2, you
must provide a network number range. These are the names associated with
the network number range entered above. You must specify at least one name,
but it isn’t necessary to specify a name for every number in the range. Zone
names may be up to 32 characters in length.
Typically names are chosen which have some significance to the physical
location or the corporate purpose of the network segment(s). Examples would
be “Main Accounting,” “Cost Accounting” and “Bookkeeping.”
These names will appear in the Chooser program of computers which support
AppleTalk. using the Network Control Panel, Macintosh computers are able
to pick the zone in which they are located.
Phase 2 Default Zone
Use the Default button next to the Zone list to select which entry the router
should designate as the default zone name for the segment(s) which are part
of the group. If you do not specify a default name, the router will designate
the first name in the list.
Phase 2 Node
You can provide a suggestion for the node number the router should use on
this AppleTalk Phase 2 Bridge Group.
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.
