I disagree this this. Not to say you're wrong, I just don't agree. I don't believe any "problems" that exist in the Native IOS are due to it not being "mature". The fact is all code, CatOS (Hybrid) and other IOS on routers, etc all have bug and problems with everything from CEF, IP, IPX, etc. I know first hand (because of worked at both places) that one of the worlds largest financial investment institutions as well as the second largest credit card company in the world both run many 6500s at various places in their network (distribution/core) and they all run Native IOS without any more problems than their 7500s, 12000s, etc. With CEF being the default for IP routing, the 6500's can route packets as fast as it could switch them on L2, so L3 performance is very capable of handling very high traffic throughputs (not that Native IOS provides this performance, I'm not claiming it does). I simply cannot believe, and have never been told by Cisco, that Cisco recommends CatOS (along with IOS on the MSFC for L3 services) over Native is you are doing heavy-duty routing. (Actually our Cisco SE suggested we go to Native from Hybrid because that's the direction Cisco was moving.) Mike W.
