84 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.
