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 Nokia Network Voyager Reference Guide. Under routing options in Network 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 Network Voyager and the related reference materials, see "Accessing Nokia Network Voyager" on page 30. 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 Network 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 IP300 Series 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.

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
Nokia
Network Voyager Reference Guide
.
Under routing options in Network 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 Network Voyager and the related
reference materials, see
“Accessing Nokia Network Voyager”
on page 30.
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 Network 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 IP300 Series 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.
