Chapter 4 - AppleTalk Routing & Bridging
v Note:  In transitional routing installations, the same range of possible 
AppleTalk network numbers is used by both Phase 1 and Phase 2. Care must 
be taken to avoid network number conflicts in these installations.

Phase 1 Routing/Off
These radio buttons control whether AppleTalk Phase 1 packets received by 
a member interface of the AppleTalk Phase 1 Bridge Group are passed on for 
AppleTalk routing.
If set to Phase 1 Routing, then AppleTalk Phase 1 packets received on a 
member interface of the AppleTalk Phase 1 Bridge Group which cannot 
simply be bridged to another member interface of the group are passed 
on for AppleTalk routing.
If set to Phase 1 Off, then AppleTalk Phase 1 packets received on a 
member interface of the AppleTalk Phase 1 Bridge Group which cannot 
be bridged to another member interface of the group are dropped. This 
setting means that further AppleTalk configuration information is not 
required for the AppleTalk Phase 1 Bridge Group.
Phase 1 Seed Status
One of the functions which routers perform in AppleTalk internetworking is 
setting the AppleTalk network number for each network segment. A router 
which sets the network number for a segment is said to have “seeded” the 
network.
Seed means the router will listen for an AppleTalk Phase 1 network 
number being set by another router on the segment(s) which are members 
of the AppleTalk Phase 1 Bridge Group and use this number if it exists. 
If it doesn’t discover a number in use, the router will use the configured 
AppleTalk Phase 1 Net # (discussed below) to set the Phase 1 network 
number for the segment(s). It will also assign the configured Phase 1 
Zone
 name to the segment(s).
Non-Seed means the router will listen for an AppleTalk Phase 1 network 
number being set by another router on the segment(s) which are members 
of the AppleTalk Phase 1 Bridge Group and use this number if it exists. 
If it doesn’t discover a number in use, the router will wait indefinitely 
until a number is set by another router on the segment(s).
Auto-Seed means the router will listen for an AppleTalk Phase 1 
network number being set by another router on the segment(s) which are 
members of the AppleTalk Phase 1 Bridge Group 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.
