Joel,

In the 64share solution the prefix is assigned to the _link_ between then PE and the CE.
The CE steals that prefix and assigns it to downstream interfaces.

In PD the prefix is delegated (as in the authority of the prefix changes) to the CE.

Do you understand the difference? And the implications of that difference?

I.e. that prefix lifetime is limited to the lifetime of the connection.
Again, we do not know how to operate networks with rapidly changing addresses.

Cheers,
Ole
