VERIFYING ROUTING PROTOCOLS

IP Routing Operational?

3.Determine if a local IP Host A has learned the route to 192.1.1.0 from System A. On IP Host A type:

netstat -r <return>

If the route to 192.1.10 is displayed, the IP RIP output processing is operational.

4.If the route is NOT displayed, try the following:

a.Using the ipnetif Manage Mode command, verify that the IP RIP Send Control is set to a RIP version that the IP Host can understand.

b.If the command shows Do Not Send, the IP RIP output processing is disabled on the interface. Correct the RIP Send Control configuration using CFGEDIT.

c.If the command shows an improper version of RIP, correct the RIP Send Control to the proper RIP version that the IP Host can understand.

5.Enter the ip rip stats administrative console command. Look for the IfStatSentResponses counter for the interface, which shows the number of RIP update messages sent on the interface.

a.If the counter is 0, enter the ip rip send administrative console command to force the RIP update message to be sent immediately.

b.Reissue the ip rip stats command.

c.If the counter is still 0, there is an unexpected condition present within the CyberSWITCH software. Contact Customer Support.

6.If the RIP Send Control is set to “RIP Version 1” or “RIP Version 1 Compatibility,” use Manage Mode to verify that the transmit broadcast address on the interface is set to a proper address that the IP Host can receive (through issuing the ipnetif Manage Mode command).

7.If the transmit broadcast address is not set properly, use CFGEDIT to correct it.

8.Check the IP Host and ensure that it is set up to learn route information via RIP.

IP RIP INPUT PROCESSING ON A LAN INTERFACE

To verify that IP RIP Input Processing (routes learning) is properly operational on a LAN interface, IP RIP processing must be successfully initialized. Also, a local IP router must be connected to the local LAN port on the system and capable of propagating routes information via RIP.

Below is an example of a configuration used to verify IP RIP input processing on a LAN interface. It uses IP addresses specified to the example. Substitute the IP addresses of your network when you perform the verification steps. It also uses the netstat command. The netstat command displays the IP routing table of the system. Substitute the equivalent command on your IP router.
