To quote from the draft (anyone read it?:-) " 6rd [RFC5969] utilizes the same encapsulation and base mechanism as 6to4, and could be viewed as a superset of 6to4 (6to4 could be achieved by setting the 6rd prefix to 2002::/16). However, the deployment model is such that 6rd can avoid the problems described here. In this sense, 6rd can be viewed as superseding 6to4 as described in section 4.2.4 of [RFC2026]" 6rd good; 6to4 {as described in section 4.2.4 of [RFC2026]} bad.
