Chapter 4 - AppleTalk Routing & Bridging
v Note: Although Compatible Systems routers support AppleTalk Phase 1,
we recommend that all new AppleTalk installations use AppleTalk Phase 2,
which is much more capable.

v Note: In transitional routing installations, the same range of potential
AppleTalk network numbers is shared by both Phase 1 and Phase 2. Care
must be taken to avoid network number conflicts in these installations.

If set to Phase 1 Bridging, then any AppleTalk Phase 1 packets received
on this interface are forwarded to the router’s internal bridge. This setting

Bridge Group” for this router.

v Note: The Phase 1 Bridging radio button will be grayed out unless
bridging has been turned on globally for the device using the Main Bridging
Configuration Dialog Box (under Global/Bridging) and locally on this inter-
face using the Bridging: Ethernet Dialog Box (under Ethernet/Bridging).

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 connected to this
interface 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. It
will also assign the configured Phase 1 Zone name to the segment.

Non-Seed means the router will listen for an AppleTalk Phase 1 network
