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.

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:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IpRip\Parameters AnnounceRouteFilters Data type = REG_MULTI_SZ Data = x.x.x.x Description = List of routes to filter out when announcing routes. The data field represents the "Network Address" of the route. AcceptRouteFilters Data type = REG_MULTI_SZ Data = x.x.x.x Description = List of routes to filter out when accepting routes. The data field represents the "Network Address" of the rout

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".
