Troubleshooting
OSPF does not operate
Problem OSPF is not configured.
Solution Verify that OSPF is properly configured for all interfaces that are
involved in OSPF routing. For more information, view Configuring OSPF
from the Configuring Routing page (press the Doc button) in Voyager.
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 The attached appliances do not support OSPF.
Solution Ensure that the attached appliances support 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.

can enable several types of trace options for RIP. These traces are logged in

use inconsistent subnet masks, change to RIP v2 or OSPF.
