iLya,
I'm sorry, it seems that we do NOT have any good documentation on CCO which provides any indepth documentation on how the IOS MLPPP implementation works. We've had a lot of churn in the implementation over the last couple of years, so it would certainly behoove us to get our act together in this regard ... I'll have to put this on my to-do pile.

Aaron
