IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.



SUMMARY
Windows NT 4.0 Service Pack 4 includes two additional configuration options for the Routing Information Protocol (RIP) Version 1 for Internet Protocol (IP). The two new options let you control what routes are announced or accepted by IP RIP on your computer.



MORE INFORMATION
The following registry parameters can be added to change the behavior of IP RIP included in Microsoft Windows NT Server version 4.0 with Service Pack 4.

NOTE: These parameters are not valid for the version of IP RIP included in the Routing and Remote Access Service Update (RRAS). RRAS is available for download from the following Web site:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To make changes using Registry Editor:


 * 1) Run Registry Editor (Regedt32.exe).
 * 2) Go to the following key in the registry:

NOTE: When entering a value or values in the "Data" (Network Address) field above, you must take into account that IP RIP version 1 only supports the default classes. For example, if you wanted to filter a route table entry to the 131.107.35.0 network, you would use a value of "131.107.0.0" in the "Data" field, NOT "131.107.35.0".
