IPv6CP (part of PPP) can't negotiate IP addresses like IPCP does for IPv4. So the WAN side needs SLAAC and/or DHCPv6 for that purpose. The next step is to get a prefix for your LAN (prefix delegation). That's done via DHCPv6. And then your router can use one address of the delegated prefix for its LAN interface and assign the other addresses to LAN clients. Your router can also delegate sub-prefixes (within the prefix delegated by your provider) further down.
