Chapter 4 - AppleTalk Routing & Bridging 77
> AppleTalk On/Bridging/Off
This set of radio buttons controls how AppleTalk packets are handled for this
interface.
• If set to AppleTalk On, then AppleTalk packets received on this inter-
face are routed to the correct interface on the router.
• If set to AppleTalk Bridging, then any AppleTalk packets received on
this interface are forwarded to the router’s internal bridge. This setting
makes this Ethernet interface a member of the “AppleTalk Phase 2
Bridge Group” for this router.
v Note: The AppleTalk 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: WAN Dialog Box (under WAN/Bridging).
• If it is set to AppleTalk Off, then any AppleTalk packets received on this
interface are discarded.
> Numbered Interface
This check box determines whether the Wide Area Network connected to this
interface will have an AppleTalk network number associated with it.
Many WAN connections are simple point-to-point links. These links do not
generally require a network number because there are only two devices on the
link. All traffic sent from one end is, by definition, destined for the other end.
You generally do not need a numbered WAN interface if you are using the
PPP transport protocol.
In contrast, Frame Relay networks may have a number of participating
routers connected through a single physical interface. Because of this, use of
the Frame Relay transport protocol requires a numbered WAN interface.
• If checked, then you must set an AppleTalk Network Number and Zone
(as described below) for this WAN interface. The default is unchecked.
Network Number
If you have set this interface to be a numbered interface, you must provide a
network number to identify the WAN link. This number creates a
“non-extended” AppleTalk network on the WAN link. Acceptable values
vary from 1 to 65,279.
v Note: Accidental selection of an AppleTalk network number which is
already in use on another network segment may cause hard-to-diagnose
problems. You should carefully track which AppleTalk network numbers are
in use, and where they are used.
