Description
Using the debugging ospf command, you can enable OSPF debugging. Using the
undo debugging ospf command, you can disable the function.
In OSPF multi-process, using debugging command, you can enable the debugging
of all the process simultaneously or one of the processes only.
If no process number is specified in the debugging command, the command is
valid to all the processes. And it keeps the state during the router running period
no matter OSPF process exits or not. In this way, the execution of this command
will enable/disable each enabled OSPF debugging. At the same time, the
debugging specified by this command will be enabled automatically when new
OSPF is enabled.
If there is a specified process number in the debugging command, only the
specified process is debugged. The configuration command is invalid if OSPF is not
enabled. And the debugging state will not be kept after exiting the process, either.
For the related command, see display debugging ospf.
Example
Enable the information debugging of OSPF packets.

Parameter
value: Default routing cost of external route imported by OSPF, ranging from 0
to 16777214. By default, its value is 1.
Description
Using the default cost command, you can configure the default cost for OSPF to
import external routes. Using the undo default cost command, you can restore the
default value of the default routing cost configured for OSPF to import external
routes.
Since OSPF can import external routing information and propagate it to the entire
autonomous system, it is necessary to specify the default routing cost for the
protocol to import external routes.
If multiple OSPFs are enabled, the command is valid to this process only.
Example
Specify the default routing cost for OSPF to import external routes as 10.
[3Com-ospf-1] default cost 10
