Wanna get some undocumented OSPF commands ?

Here's the list:

SHOW IP OSPF EVENTS

SHOW IP OSPF STATISTICS

SHOW IP OSPF MAXAGE

SHOW IP OSPF BAD-CHECKSUM

SHOW IP OSPF DELETE-LIST

SHOW IP OSPF TIMERS LSA

And here are some sample outputs:

SHOW IP OSPF EVENTS

This is a sample output from the command:

SHOW IP OSPF MAXAGE
(when testing above command I found you must be
in the enable mode to see anything)

This is a sample output from the command:

Router#sh ip o maxage
AS System 1
Maxage delete timer due in NEVER
Router#

SHOW IP OSPF BAD-CHECKSUM

This is a sample output from the command (thanks to Aki Anttila from Finland):

SHOW IP OSPF DELETE-LIST

This is a sample output from the command:

sh ip o dele

(BTW: Watch out ! There is a famous command "sh ip o d ", which usually translates to
"show ip ospf database" in most IOS'es. I experienced with some versions that instead
the database you would be shown the delete list !!! )

SHOW IP OSPF TIMERS LSA

This is a sample output from the command:
