Jiang, I'm running IOS 12.1 in my lab. Clear IP OSPF process does not clear
out bad or old RID information
Various experiments over the last couple of days, both as a result of this
thread and private conversations, led to my discovery that blowing out the
OSPF configuration completely, then rebuilding it, will remove the bad
information ( such as a bad neighboring RID ). And so will reloading the
router. But once RID's are learned, at least in what I have seen so far, it
is hell getting "rid" of them.

In some ios versions (maybe 12.0 GD), you can use "clear ip ospf process"
command to restart OSPF.
