Follow-on ?? to Cisco IOS ver and clfowd

Ok, I am blue in the face now...

Is there a cisco release naming / feature
expert in the house ??:slight_smile:

What version of IOS properly supports
IP, BGP, NAT, ISL and NetFlow

where ALL of this stuff works.

I tried 11.1(18)CC it has the Netflow stuff
but ISL is broken
