6000 PPP users on a NPE-G2 is way too much imho. Currently we do no more than 3000 users on a NPE-G2 with PPPoA. (Max cpu 50%). 5 years ago, we did about 5000 users on a NPE-G2, but as traffic ratio's grow each year the maximum users a NPE-G2 can handle will drop each year. Don't forget an

For this application, you may wish to consider the service provider images. The latest 15.x(S) image works, as it is the derivative of what was formerly the service-provider oriented 12.2(SRx) images. However, it's unlikely to drop steady state CPU, but it may contain some optimizations for

Second, in the hotspot scenarios where this is likely to be a problem (in IPv4 -or- IPv6) it's addressed by the AP isolation feature that's getting close to omnipresent even in the low end APs. With this feature enabled, stations are not allowed to talk to each other over the wlan; they can
