Of course, the *real* answer which everyone seems to be overlooking is that you're terminating PPPoE-over-L2TP per Paul's original mail. The encap/deencap is the limiting factor, and you're gonna pummel any known NPE up to and including the NPE-G1 before you hit the link speed limit with ATM or

An NPE-G1 easily handles 2 full ATM-OC3's worth of L2TP tunnels. We have several of these in production, and typically hit around 60% CPU utilization. - Original Message --- Subject: Re: [c-nsp] OC3 Throughput From: Robert E. Seastrom [EMAIL PROTECTED] Date: Mon, 26 Nov

Hi folks... Looking for input on *realworld* maximum throughput on an OC-3 circuit? This is a Cisco 7206VXR with a OC-3 card with l2tp tunnels coming into the router servicing PPPOE clients over ADSL. Thanks, ___ cisco-nsp mailing list
