Thanks for all the replies. No clear answer yet. I do know for a fact due to debugs that there is a periodic key exchange sequence. The debug would show as OSPF: Send with youngest Key 1. The traffic would come across as 224.0.0.5. The only difference between the demand-circuit peers staying up or being terminated is no authentication versus authentication. And actually the area number doesn't matter. Also be aware, I found this out the hard way, that you can actually have blank spaces after your key value which will not be visible. This cost me hours of trouble shooting until I deleted and readded my key statements. Ooops.
