Hello Nasser. We use IPoE in our small ISP. But in my case we use DHCP option 82 and IP address as username for authentication and accounting purposes. As BRAS we configure Cisco ISG.

Hi, We are currently using PPPoE in our network. I have seen some articles regarding migration of so-called legacy PPPoE to IPoE. After reviewing some of them and implementing IPoE in lab environment using Cisco ASR I didn't fine it that much beneficial to migrate whole system as I need to change a lot of things. For example: - I need to add it's support to our radius and obviously BSS system (E.g. using NAS-PORT-ID instead of username). - For the addressing part, as I have already using distributed BNG's, I need to change some of our policies. (For example assigning address blocks is much easier in PPPoE using framed-route) - I need to change our customers CPE configuration to use Ethernet encapsulation. - I haven't used DHCP in large scale environment. - I don't have any clear Idea/understanding regarding its maintainability/troubleshooting and also security. (Please add if I'm missing any other issue which may run into if I migrate to IPoE) Although it has some benefits, I'm not sure if it's that essential to migrate. Would you please kindly? - Share your Ideas/experiences/best practices in this regard? - If you are already using IPoE, tell more why should I upgrade? - Considering a DSL network with more than 800K customers using PPPoE, do you recommend this migration? Kind Regards, Nasser
