Troubleshooting
Common Problems with RIP
Use tcpdump to view routing information. Use the following command to
display routing updates for a specific interface:
tcpdump -i interface proto rip
For more information about how to use the tcpdump command, see the
Voyager Reference Guide.
Under routing options in Voyager, you can also enable several types of trace
options for routing information protocol (RIP). These traces are logged in
/var/tmp/ipsrd.log

Problem Inconsistent subnet mask (netmask does not match the class of IP
address for RIP v1).
Solution RIP version 1 must use consistent subnet masks; change to RIP
version 2 or OSPF to use inconsistent subnet masks.
Problem Number of networks exceeds the RIP limit.
Solution RIP can span up to 16 networks. Verify that your network
topology does not exceed this limit.
Common Problems Exchanging Routes
Always enter a metric value if you are exporting routes from OSPF to RIP.
Problem Exchanging routes are not configured correctly.
Solution Exchanging routes involves several configuration steps. Follow
the tasks in the Voyager Reference Guide (online documentation) to ensure
that you follow all steps.
