Hi a small question: If i add Netflow on a Cisco 1721 routers with a 2 Mbits WAN link, that's use a big quantity of CPU/Memory ? If the server that receive the flow information are on the Wan, that"s use a big quantity of bandwith ? The Cisco 1721 are used into a Mpls IP VPN (no ipsec) and with a BGP Network (~90 routes) Thanks Stephane
