MPR (Multi-Protocol Router) consists of the following: RIP (Routing Information Protocol) for TCP/IP, BOOTP (Boot Protocol) relay agent for DHCP, and RIP for IPX. RIP is used by routers to dynamically exchange routing information. With RIP for IP and RIP for IPX installed, Windows NT will route these protocols and dynamically exchange routing information with other routers running the RIP protocol. The BOOTP relay agent will allow the Windows NT Router to forward DHCP requests to DHCP servers on other subnets. This allows one DHCP server to service multiple IP subnets. See Riproute.wri in the MPR directory for additional documentation on MPR.
InstallationMPR requires Windows NT Server 3.51 and Service Pack 2. In addition, two or more network cards are needed for full MPR functionality.
To install MPR:
RIP for IP, Configuration and TroubleshootingNo manual configuration is needed. After installing RIP for IP, the Enable IP Routing box in Advanced TCP/IP configuration will automatically be selected. RIP for IP runs as a service and can be stopped and started using Control Panel Services.
To see what routes your computer has, type ROUTE PRINT at the Windows NT Command Prompt. This will show the routes that Windows NT creates by default, 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 RIP broadcasts and updates its route table but does not advertise its own routes. 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 TroubleshootingAfter you install the BOOTP Relay Agent you will be prompted with a configuration screen. You must enter the IP address of DHCP servers that you would like to send DHCP requests to. Maximum Hops and Seconds Threshold can 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 TroubleshootingWhen installing RIP for NWlink, Setup displays a message that NetBIOS Broadcast Propagation (broadcast of type 20 packet) is currently disabled. If you are using NetBIOS over IPX or are unsure, choose Yes to enable broadcast of type 20 packets. Reboot the computer as directed. Type 20 broadcast can be later configured by selecting RIP for NWlink IPX in Control Panel Network and clicking configure.
Enable RIP Routing is automatically selected when you install RIP for NWlink IPX. RIP for NWlink IPX can be enabled or disabled by clicking Enable RIP Routing in NWlink IPX/SPX Protocol Configuration. The SAP agent is automatically installed with RIP for NWlink IPX. SAP is a service, and can be started and stopped from Control Panel Services. Microsoft recommends that you configure the Internal Network number through the NWLink configuration in Control Panel Network. If you do not, a random number will be generated for you.
The command line utility Ipxroute.exe has been updated and can be used to get RIP, SAP, and source routing information and statistics.
