Re: PPPoE/IPoE, any recommendations for upgrade?

[Sabri Berisha <sabri () cluecentral net>]

Hi,

I used to work for Redback (who were acquired by Ericsson), and their SmartEdge BNG supports a feature called CLIPS. 
CLIPS is basically IPoE towards the clients (DHCP based), but with BRAS features. The mac address of the client will be 
authenticated against your RADIUS and you can pretty much use the same policies as you're used to on PPPoE (with the 
exception of multicast-related policies of course). I'm not sure, but I think other vendors have similar features 
nowadays. This might help your migration.

Thanks,

Sabri
