Troubleshooting Routing Problems
Common Problems with OSPF
Use tcpdump to view routing information. Use the following command
display routing updates for that interface:
tcpdump -i interface proto ospf
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 OSPF. These traces are logged in .
/var/tmp/ipsrd.log
For information about how to access Voyager and the related reference
materials, see "Accessing Nokia Network Voyager" on page 34.
Problem OSPF is not configured.
Solution Verify that OSPF is properly configured for all interfaces that are
involved in OSPF routing. For more information, see Configuring OSPF from
the Configuring Routing document page in Voyager. You can access the
document page by pressing Doc.
Problem OSPF hello and dead timers are not the same on each interface for
a given link.
Solution Verify that the settings at the end of each link are identical.
Problem Attached devices do not support OSPF.
Solution Ensure that the attached 60s and 100s appliance supports OSPF.
If the attached appliance does not support OSPF, configure it with a protocol
that the appliance supports and exchange routes with OSPF, or set a default or
static route.
Note
You can also use ICLID to display OSPF details.
