While it is true that PPP is not used here, I won't say that PPP should be avoided. PPP is a valid and widely deployed model in DSL Broadband environment; Broadband Forum has already published TR-187 that explains how to deploy IPv6 with PPP. In addition in case of bridged Layer 2 RG model, PPP + SLAAC with the /64 announced in the RA PIO is a valid solution.

PPP is not used here.
