Configuring NWLink
Once NWLink has been installed you need to properly configure it. By default, NWLink
automatically detects the frame type used on the LAN because
it is set to auto detect the network frame type. If NWLink
detects no network traffic or if multiple frame types are
detected as in use, NWLink sets the frame type to 802.2.
Each frame type on a IPX network
formats data differently for transmission and the different
types are incompatible with each other. Multiple frame types
can be used, but in order for all computers on a network to
successfully communicate with one another, they must use the
same frame type.
You can determine which external
network number, frame type, and internal network number your
routers are using by typing ipxroute config at a
command prompt.
IPXroute.exe is a command-line
utility that allows Administrators to modify the
NWLink IPX/SPX/NetBIOS Compatible Transport Protocol
(NWLink) settings that affect routing. The Ipxroute utility
provides the same functionality as the Route.exe
command-line utility that is supplied by Novell for its
MS-DOS-based clients.
The Ipxroute utility manages the source routing variables of
NWLink and is installed only if the NWLink transport
protocol is bound to a network adapter.
Any changes made with IPXroute are valid for the current
session only. When you log off, the settings are lost. To
permanently change NWLink settings, you must set them in the
registry.

NWLink IPX Routing and Source
Routing Control Program v2.00 is included in Windows 2000 and
Windows XP displays and modifies information about the
routing tables used by IPX.
H:>ipxroute

DEFault Node (Unknown) Addresses are sent SINGLE ROUTEBROADCAST
Broadcast (FFFF FFFF FFFF) Addresses are sent SINGLE ROUTEBROADCAST
Multicast (C000 xxxx xxxx) Addresses are sent SINGLE ROUTEBROADCAST
IPX Routing Options-------------------
IPXROUTE servers [/type=xxxx]
Servers displays the SAP table for the specified
server type. Server type is a 16-bit integer value. If no
type is specified, servers of all types are shown. The
displayed list is sorted by server name.
IPXROUTE ripout network
Ripout discovers the reachability of “network”
(specified in host order) by consulting the IPX Stack’s
route table and sending out a rip request if necessary.
IPXROUTE resolve guid|name adapter-name
Resolve resolves the name of the given adapter to its
guid or friendly version.
Source Routing Options----------------------
IPXROUTE board=n clear def gbr mbr remove=xxxxxxxxxxxxIPXROUTE config
board=n – Specifies the board number to check
clear – Clears the source routing table
def – Sends packets that are destined for an unknown address to the ALL
ROUTES broadcast (default is
SINGLE
ROUTE broadcast)
gbr – Sends packets that are destined for the broadcast address (FFFF
FFFF FFFF) to the ALL ROUTES broadcast (default is
SINGLE
ROUTE broadcast)
mbr – Sends packets that are destined for a multicast address (C000 xxxx
xxxx) to the ALL ROUTES broadcast (default is
SINGLE
ROUTE broadcast)
remove=xxxx – Removes the given mac address from the source routing
table
config – Displays information on all the bindings that IPX is
configured for
