Yes. But my concern was, for example, a CPE has the below mapping rule, cited from the draft: +--------------------+--------------------+-------------------------+ | Domain IPv4 prefix | Domain IPv6 prefix | AFTR IPv6 subnet (e.g.) | +--------------------+--------------------+-------------------------+ | 192.32../12 | 2001:db0::/28 | 2001:db0:aaaa:aaaa::/64 | +--------------------+--------------------+-------------------------+ when the CPE forwards a IPv4 packet whose destincation address is within 192.32../12, how the CPE know it will use /48 CE prefix or /52 CE prefix? Or the mapping rule implies the CPE should use the same CE preifx length as its own delegated prefix?
