84 | Chapter 4 - AppleTalk Routing & Bridging |

ϖ 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).
