Hi,
draft-ietf-softwire-ipv6-6rd-03 describes how prefixes are automatically
delegated.
It also describes IPv6 in IPv4 encapsulation.
However, if CPE has native dual-stack WAN connection, with BR locating at the
first hop (say point-to-point connection), what is the problem in CPE obtaining
these automatically delegated prefixes as described in 6RD (i.e. based on CPE's
IPv4 address), but without need to encapsulate IPv6 packets in IPv4?
Thanks,
Teemu
