Again, I don't recall putting any words in Randy's mouth, if I did, it was unintentional.  However...

Periodic updates of the entire routing table *with much larger and more updates* seems undesirable at best to me, particularly to ""reduce the vulnerability window for replay attacks" to "days".

I suggest we stick with the current triggered updates operation or take this to IDR, it's a fundamental change from where we are today, and one's perspective of "excessive routing churn" seems to be relative.
