Sing-Yu,
It is a hidden command. 12.2 is no problem, I am not sure for 12.1.
Just type in debug ip ospf monitor, see if it accepts it. According
to your information, it looks like you have some sort of access-list
applied somewhere. It triggered the dial and then be denied.
hope this will help,
Song
