It's worth bearing in mind that some netflow options require pre-export lookups in software; namely egress interface, BGP AS, BGP next hop - all of which require punting to the *RP*. In addition, I believe the 6708-10G will export the netflow using the DFC CPU, not even loading the SP CPU. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
