SUMMARY
The following registry parameters can be modified to change the behavior of Routing Information Protocol (RIP) for Internet Protocol (IP) included in Microsoft Windows NT Server version 4.0 and Microsoft Windows NT Server version 3.51 Service Pack 2 and above.

NOTE: These parameters are not valid for the version of RIP included in the Routing and Remote Access Service Update. The Routing and Remote Access Service Update is available for download from www.microsoft.com and ftp.microsoft.com.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

To make changes using Registry Editor:
 * Start the Registry Editor by running the Regedt32.exe.

-or-

At the command prompt, type Regedt32, and then press ENTER. When the Registry Editor window appears, you can press F1 to get Help on how to make changes in Registry Editor.


 * In Registry Editor, click the window titled HKEY_LOCAL_MACHINE On Local Machine, and then click the icons for the SYSTEM subtree until you reach the appropriate subkey, as described later in this section.

The Registry parameters for IP RIP are specified under the following key:

  SYSTEM\CurrentControlSet\Services\IpRip\Parameters

AcceptDefaultRoutes Data type = REG_DWORD Range = 0 or 1 Default = 0 If set to 1, default routes in received RIP announcements are accepted. By default, they are ignored.

AcceptHostRoutes Data type = REG_DWORD Range = 0 or 1 Default = 0 If set to 1, host routes in received RIP announcements are accepted. By default, they are ignored.

AnnounceDefaultRoutes Data type = REG_DWORD Range = 0 or 1 Default = 0 If set to 1, default routes are included in RIP announcements.

AnnounceHostRoutes Data type = REG_DWORD Range = 0 or 1 Default = 0 If set to 1, host routes are included in RIP announcements.

EnablePoisonedReverse Data type = REG_DWORD Range = 0 or 1 Default = 1 By default, if a RIP announcement contains a route that was previously advertised by that route, then that route is announced on the network with a metric of 16.

EnableSplitHorizon Data type = REG_DWORD Range = 0 or 1 Default = 1 By default, routes learned on a network are suppressed in updates sent on that network. If the parameter is set to 0, routes learned on a network are announced on the same network, as well.

EnableTriggeredUpdates Data type = REG_DWORD Range = 0 or 1 Default = 1 By default, new routes and metric changes trigger an immediate update that includes only the changes. The time between updates depends on the value of MaxTriggeredUpdateFrequency.

GarbageTimeout Data type = REG_DWORD Range = 15 seconds - 259200 seconds (72 hours) Default = 120 seconds The number of seconds to wait before removing a route marked for garbage collection.

LoggingLevel Data type = REG_DWORD Range = 0 - 3 Default = 1 The minimum level of information for entries being made to the system log; 0 = no logging, 1 = errors, 2 = warnings, 3 = information.

MaxTriggeredUpdateFrequency Data type = REG_DWORD Range = 1 second - 884400 seconds (24 hours) Default = 5 seconds The minimum number of seconds that must elapse between triggered updates.

RouteTimeout Data type = REG_DWORD Range = 15 seconds - 259200 seconds (72 hours) Default = 180 seconds The number of seconds to wait before marking a route for garbage collection.

SilentRip Data type = REG_DWORD Range = 0 or 1 Default = 0 If set to 1, suppresses periodic RIP announcements.

UpdateFrequency Data type = REG_DWORD Range = 15 seconds - 884400 seconds (24 hours) Default = 30 seconds The number of seconds between periodic updates that contain the entire routing table. This entry also determines the period at which the route table is updated from received RIP updates.
