[bcop] A question about RIPE-690

Hello all,

I have a question about RIPE-690. In section 4.1.1 it says:

<quote>
Using a /64 prefix from a dedicated pool of IPv6 prefixes is the most common scenario and currently the best practice. A separate block of IPv6 space is allocated for the WAN links to the end customer CPEs, so that when CPE connects to the network and performs router discovery, a /64 prefix is used to number both ends of the connection.
</quote>

My question is that:

Is the /64 prefix common for all WAN links or a separate /64 prefix is to be allotted for each WAN link? It may be obvious, but from reading the docs its not clear for me.

I understand that for PD it has to be a separate prefix for each customer CPE.

Apologies if this is not the right forum for asking this question.

X.
