Chapter 4 - AppleTalk Routing & Bridging
>
Phase 2 Routing/Off
These radio buttons control whether AppleTalk Phase 2 packets received by 
a member interface of the AppleTalk Phase 2 Bridge Group are passed on for 
AppleTalk routing.
If set to Phase 2 Routing, then AppleTalk Phase 2 packets received on a 
member interface of the AppleTalk Phase 2 Bridge Group which cannot 
simply be bridged to another member interface of the group are passed 
on for AppleTalk routing.
If set to Phase 2 Off, then AppleTalk Phase 2 packets received on a 
member interface of the AppleTalk Phase 2 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 2 Bridge Group.
Phase 2 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 2 network 
range being set by another router on the segment(s) which are members 
of the AppleTalk Phase 2 Bridge Group and use this range if it exists. If 
it doesn’t discover a range in use, the router will use the configured 
AppleTalk Phase 2 Net # range (discussed below) to set the Phase 2 
network number(s) for the segment(s). It will also assign the configured 
Phase 2 Zone list to the segment(s).
Non-Seed means the router will listen for an AppleTalk Phase 2 network 
range being set by another router on the segment(s) which are members 
of the AppleTalk Phase 2 Bridge Group and use this range if it exists. If 
it doesn’t discover a range in use, the router will wait indefinitely until a 
range is set by another router on the segment(s).
Auto-Seed means the router will listen for an AppleTalk Phase 2 
network range being set by another router on the segment(s) which are 
members of the AppleTalk Phase 2 Bridge Group and use this range if it 
exists. If it doesn’t discover a range in use, the router will auto-generate 
a valid number (a range of size 1) using its routing tables.
Phase 2 Net # Range
For an AppleTalk Phase 2 Bridge Group which you set to Seed Phase 2, you 
must provide a network number range. These two decimal numbers uniquely 
identify the range of AppleTalk network numbers for the network segment(s)
