 40: OSPF C

ONFIGURATION

By default, OSPF TRAP is disabled, that is, OSPF process does not forward TRAP 
packets. If the process number is not specified during configuration, OSPF TRAP 
configuration will be valid for all OSPF processes.

For detailed configuration about SNMP TRAP, refer to Part II “System 
Management”.

If the 

 command is executed on a router and then the 

 command is 

used to reset an OSPF process, the previous OSPF configuration will be lost. With 
the 

 command, you can reset the OSPF process without losing the 

previous OSPF configuration.

Perform the following in the User View.

Resetting the OSPF process can immediately clear the invalid LSAs, make the 
modified Router ID immediately effective or re-elect the DR and BDR.

If the process number is not specified, all OSPF processes will be reset.

After the above configuration, execute 

 command in all views to display 

the running of the OSPF configuration, and to verify the effect of the 
configuration. Execute 

 command in user view to debug the OSPF 

module.
