Multi-Protocol Router Installation and Configuration

This article was previously published under Q138793
MPR (Multi-Protocol Router) consists of the following: RIP (RoutingInformation Protocol) for TCP/IP, BOOTP (Boot Protocol) relay agent forDHCP, and RIP for IPX. RIP is used by routers to dynamically exchangerouting information. With RIP for IP and RIP for IPX installed, Windows NTwill route these protocols and dynamically exchange routing informationwith other routers running the RIP protocol. The BOOTP relay agent willallow the Windows NT Router to forward DHCP requests to DHCP servers onother subnets. This allows one DHCP server to service multiple IP subnets.See Riproute.wri in the MPR directory for additional documentation on MPR.


MPR requires Windows NT Server 3.51 and Service Pack 2. In addition, two ormore network cards are needed for full MPR functionality.

To install MPR:
  1. Run UPDATE.EXE from the MPR\i386 directory (or the directory for the appropriate hardware type) on the Windows NT 3.51 Service Pack 2 CD-ROM disc.

    Update.exe copies files to your Windows NT installation and make new software choices available under Control Panel Network (Add Software).

    NOTE: You need to run this UPDATE.EXE program in addition to the UPDATE.EXE program used to install Service Pack 2.
  2. Run Control Panel, click Network, and click Add Software.
  3. Select RIP for Internet Protocol, Bootp Relay Agent, or RIP for NWlink IPX/SPX compatible transport, and then click Continue.
  4. When prompted, provide the path for the MPR distribution files (for example, D:\MPR\I386).
WARNING: After you install RIP, Windows NT will start exchanging routinginformation with other RIP routers. If you have misconfigured the IPaddress of your network cards or used a fake IP address, this could have asevere impact on your network. Do not install RIP without fullyunderstanding TCP/IP and the design of your network.

RIP for IP, Configuration and Troubleshooting

No manual configuration is needed. After installing RIP for IP, the EnableIP Routing box in Advanced TCP/IP configuration will automatically beselected. RIP for IP runs as a service and can be stopped and started usingControl Panel Services.

To see what routes your computer has, type ROUTE PRINT at the Windows NTCommand Prompt. This will show the routes that Windows NT creates bydefault, and routes learned through RIP.

If RIP for IP is installed on a computer that has only one network card,it is configured for Silent Mode. In Silent Mode, Windows NT listens to RIPbroadcasts and updates its route table but does not advertise its ownroutes. If an additional network card is later installed in the computer,RIP will automatically turn off Silent Mode and enable IP routing.

Bootp Relay Agent, Configuration and Troubleshooting

After you install the BOOTP Relay Agent you will be prompted with aconfiguration screen. You must enter the IP address of DHCP servers thatyou would like to send DHCP requests to. Maximum Hops and Seconds Thresholdcan be left at the defaults. If you later need to change the configuration,click the Config Relay Agent button under Advanced TCP/IP Configuration.

RIP for NWlink IPX/SPX compatible Transport,Configuration and Troubleshooting

When installing RIP for NWlink, Setup displays a message that NetBIOSBroadcast Propagation (broadcast of type 20 packet) is currently disabled.If you are using NetBIOS over IPX or are unsure, choose Yes to enablebroadcast of type 20 packets. Reboot the computer as directed. Type 20broadcast can be later configured by selecting RIP for NWlink IPX inControl Panel Network and clicking configure.

Enable RIP Routing is automatically selected when you install RIP forNWlink IPX. RIP for NWlink IPX can be enabled or disabled by clickingEnable RIP Routing in NWlink IPX/SPX Protocol Configuration. The SAP agentis automatically installed with RIP for NWlink IPX. SAP is a service, andcan be started and stopped from Control Panel Services. Microsoftrecommends that you configure the Internal Network number through theNWLink configuration in Control Panel Network. If you do not, a randomnumber will be generated for you.

The command line utility Ipxroute.exe has been updated and can beused to get RIP, SAP, and source routing information and statistics.

For more information on MPR, refer to Riproute.wri in the Windows NT3.51 Service Pack 2 CD-ROM disc \MPR directory.
