## SUMMARY

NWLink parameters that affect routing in a token ring environment can be modified for the current Windows NT session with the command line utility IPXROUTE.EXE (IPXRoute). The command line syntax is:

ipxroute board=n [clear] [def] [gbr] [mbr] [remove=xxxxx]

## MORE INFORMATION

Listed below are descriptive information on the IPXRoute syntax.

       Parameter       Description
       -----------------------------------------------------------------------
       board=n         Specifies the board number (frame type) to check.
       clear           Clears the source routing table.
       def             Forwards packets as All Routes Broadcast frames if its
                       media access control (MAC) address is not in the source
                       routing table.
       gbr             Forwards general broadcast packets, those addressed to
                       the broadcast address (FFFFFFFFFFFF), as All Routes
                       Broadcast frames.
       mbr             Forwards multicast broadcast packets, those addressed
                       to a multicast address (C000xxxxxxxx), as All Routes
                       Broadcast frames.
       remove=xxxxx    Removes the given node address from the source routing
                       table.

NOTE: The IPXRoute utility changes NWLINK parameters only for the current Windows NT session. In order to permanently change NWLink parameters, you must set them in the Registry.
When a computer using NWLink receives an IPX/SPX broadcast packet or an IPX/SPX packet with its node address is not in its source routing table, the computer forwards the packet as a Single Route Broadcast frame by default. IPXRoute provides the same functionality as the ROUTE.EXE command line utility supplied by Novell for its MS-DOS based clients. IPXRoute manages the source routing variables of NWLink on a token ring network. It is installed only if the NWLink transport protocol is bound to a token-ring network adapter card. IPXRoute parameters are equivalent to the ROUTE.EXE utility parameters supplied by Novell. IPXRoute utility is shipped with the Windows NT package.
