Cisco 7206 IOS for PPPoE Termination

Sun Sep 23 19:13:02 UTC 2012

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 NPE-G2 is a software based plaform, so traffic 
forwarding is done in software CPU.
