18.4.4.2 OSPF Troubleshooting Help
In configuring and using OSPF protocol, the OSPF protocol may fail to run properly due to reasons
such as physical connection failure or incorrect configuration. The user should ensure the following:
—
Good condition of the physical connection.
— All interface and link protocols are in the UP state (use “show interface” command).
— Then IP addresses of different network segments should be configured in all interfaces.
— Enable OSPF (use “router rip” command) first, then configure OSPF areas for appropriate
interfaces to reside in.
— Next, note the nature of OSPF – OSPF backbone area (area 0) must be continuous, if not, use
virtual link to make it continuous; all non-0 areas must connect to the others via area 0, direct
connection between non-0 areas is not allowed; edge layer 3 switch refers to the layer 3 switch
that partly belongs to area 0 and partly belong to non-0 area; for mutli-access network-like
broadcast networks, designated layer 3 switch (DR) should be elected.
If OSPF routing problems persist after the above-mentioned procedures, please run debugging
commands like “debug ip ospf packet” and “event”, and copy the debug information in 3 minute and
send the information to Edge-Core technical service center.
