RIP Listener does not update the route table with new route information (841804)


The information in this article applies to:

  • Microsoft Windows XP Professional Service Pack 2 (SP2)
  • Microsoft Windows XP Tablet PC Edition 2005
  • Microsoft Windows XP Media Center Edition Service Pack 2 (SP2)
  • Microsoft Windows XP Home Edition Service Pack 2 (SP2)

SYMPTOMS

If your Microsoft Windows XP-based computer is running Routing Information Protocol (RIP) Listener, RIP Listener may not update the route table with new route information.

CAUSE

This issue may occur if a firewall is preventing RIP Listener from receiving route information that is sent by routers that are using RIP version 1. When you install Windows XP Service Pack 2 (SP2), Windows Firewall is turned on. If your computer has Windows Firewall or another firewall turned on, incoming UDP port 520 may be blocked.

WORKAROUND

  1. Click Start, and then click Run.
  2. In the Open box, type wscui.cpl.
  3. Click OK.
  4. Click Windows Firewall.
  5. Click the General tab, and then click to clear the Don't allow exceptions check box.
  6. On the Exceptions tab, click Add Port.
  7. In the Port number box, type 520.
  8. Click UDP.
  9. In the Name box, type the following text:

    520 port opening for RIP Listener

  10. Click OK.
  11. Select the 520 port opening for RIP Listener check box, and then click OK two times.
