Chapter 3 - IPX Routing & Bridging 61
• If set to IPX Routing, then IPX packets received on this interface are
routed to the correct interface on the device.
• If set to IPX Bridging, then any IPX packets received on this interface
are forwarded to the device’s internal bridge. This setting makes this
interface a member of the “IPX Bridge Group” for this device.
v Note: The IPX Bridging radio button will be grayed out unless bridging
has been turned on globally for the device using the Main Bridging Configu-
ration Dialog Box (under Global/Bridging) and locally on this interface
using the WAN-Bridging Dialog Box (under WAN/Bridging).
• If it is set to IPX Off, then any IPX packets received on this interface are
discarded.
> Numbered Interface
This checkbox determines whether the Wide Area Network connected to this
interface will have an IPX 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
devices 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 IPX Network Number (as described
below) for this WAN interface. The default is unchecked.
Network Number
This is an eight-digit hexadecimal number that uniquely identifies the
network segment connected to this interface. Values range from 1 to
FFFFFFFE.
v Note: Accidental selection of an IPX network number which is already in
use on another network segment may cause hard-to-diagnose problems. You
should carefully track which IPX network numbers are in use, and where they
are used.
> Update Method
WAN interfaces which are configured to provide “dial-on-demand” service
will bring a connection up (i.e. dial the other end) when there are network
packets which must be transferred over the link. Once a dial-on-demand
