I want to use ipv6 with pppoe !!! How can I do that

Are there any explanation ??????????

Thank you very

IPv6 tunneling? so you could provide ipv6 access to your customers?
My only idea would be break your assigned /48 out into /64's and assign that to each pppoe interface on the client side of the PPPoE.
I have no idea if that would actually work though.

I need explanation???about IPv6 ??

do you know what is IPv6 and how to use it? if not, first please google

Yes I know ,But I need to learn how to take advantage of it in preparing server

I would add IPv6 tunnels to someone like HE (6-4 tunnel) so you have ipv6 internet access. And keep ipv4 also.
That way your network can move both types of ip's and when the time comes, you can turn off ipv4.

and the advantage to all this "headache" is ???

because ipv4 will be hard to get here in the next few months... better start learning now so you are prepared.
