You must install PPPoE client software on all hosts that connect to the Ethernet segment. This means that the access provider must maintain a CPE
You cannot use PPPoE with Cisco Service Selection Gateway
PPPoE implementation is susceptible to broadcast storms and possible denial-of-service attacks
Per-session accounting is possible, which allows the service provider to charge the subscriber based on session time for various services offered. The service provider can also require a minimum access charge
