Registry Parameters for RIP for IP Version 1

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:
If set to 1, default routes in received RIP announcements are accepted. By default, they are ignored.
If set to 1, host routes in received RIP announcements are accepted. By default, they are ignored.
If set to 1, default routes are included in RIP announcements.
If set to 1, host routes are included in RIP announcements.
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.
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.
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.
The number of seconds to wait before removing a route marked for garbage collection.
The minimum level of information for entries being made to the system log; 0 = no logging, 1 = errors, 2 = warnings, 3 = information.
The minimum number of seconds that must elapse between triggered updates.
The number of seconds to wait before marking a route for garbage collection.
If set to 1, suppresses periodic RIP announcements.
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.
