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
