of trace options for OSPF. These traces are logged in
/var/tmp/ipsrd.log
.

reference materials, see
“Using Nokia Network Voyager”
on page 45.
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
the
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.
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
