Hellow everyone.
I want to move from v5 to v9, but I'm not sure about the ingress\egress configuration. I got Netflow running on a central router only and it only has one interface as an export source. My corrent configuration is "ip flow ingress" on both LAN and WAN interfaces. What I want to do after v9 is turned on is to enable "ip flow ingress" and "ip flow egress" both on LAN and WAN interfaces. I'm concerned that it will make the amout of traffic double. Can anyone shed some light on that?
