Point taken. I don't want to downplay the work that you are doing, but 
when we are talking about our Core routers, the lifeblood of our 
operation, we just can't afford to make mistakes.

I've always been inclined, (based on past experiences w/ CCO) to run the 
SERVICE PROVIDER/VIP loads of IOS. I was told that this is tuned for 
Providers in several ways and makes the best choice for running high 
availability BGP routers.

Would you agree with that?

And secondly, what are the major differences between the follwing release 
trains? If there is a document that explains this, I'd be happy to read 
it.
