Other stuff: NetFlow and CEF Fun stuff. Netflow: Don't think of NetFlow in any other capacity other than for trace-back capabilities:
Thanks for the long answer, but this question was actually on how the router performance impact of CAR or TCP-Intercept changes between using CEF switching (ip route-cache cef, default) and CEF-Flow switching (ip route-cache cef + ip-route cache flow). Although NetFlow impacts router performance a little, running CEF-Flow makes large access-list processing faster than just running CEF; I think some other features (IPSec ?) also have performance gains. I was wondering whether CAR and/or TCP-Intercept would have better performance with CEF-Flow. Rubens Kuhl Jr.
