RIP Table Sent While Shutting Down When Silent RIP Set

• Microsoft Windows NT Workstation versions 3.51 and 4.0
• Microsoft Windows NT Server versions 3.51 and 4.0

SYMPTOMS

Routing Information Protocol (RIP) table information may be sent when you shut down a computer, even though Silent RIP is enabled in the registry.

CAUSE

Normally when we send RIP packets, we first check to see if the SilentRip value in the registry is set. In the case where the computer is shut down, we did not check this value.

RESOLUTION

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 disable RIP broadcasts you can set up the SilentRip registry entry.

1. Run Registry Editor (Regedt32.exe).

2. Go to the following key in the registry:

         \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
         IpRip\Parameters
   

3. On the Edit menu, click Add Value and use the following entry:

         Value Name: SilentRip
         Data Type:  REG_DWORD
         Value:      1 or 0
   
         NOTE: Setting this to 1 lets the server accept RIP but not send
         RIP packets. Setting this to 0 causes the server to also send RIP
         packets.
