Resetting the OSPF
Process
If the undo ospf command is executed on a router and then the ospf command
is used to restart the OSPF process, the previous OSPF configuration will lose. With
the reset ospf command, you can restart the OSPF process without losing the
previous OSPF configuration.
Perform the following configuration in user view.
Resetting the OSPF process can immediately clear invalid LSAs, and make the
modified router ID effective or the DR and BDR are re-elected.
Displaying and
Debugging OSPF
After the above configuration, execute the display command in any view to
display the running of the OSPF configuration, and to verify the effect of the
configuration. Execute the debugging command in user view to debug the OSPF
module.
