This document proposes an alternative IPv6 Rapid Deployment on IPv4
Infrastructures (6rd) deployment model to that of RFC 5969. The
basic 6rd model allows IPv6 hosts to gain access to IPv6 networks
across an IPv4 access network using 6-in-4 tunnels. 6rd requires
support by a device (the 6rd customer edge, or 6rd-CE) on the
customer site, which must also be assigned an IPv4 address. The
alternative model described in this document initiates the 6-in-4
tunnels from an operator-owned Gateway collocated with the operator's
IPv4 network edge rather than from customer equipment, and hence is
termed "Gateway-initiated 6rd" (GI 6rd). The advantages of this
approach are that it requires no modification to customer equipment
and avoids assignment of IPv4 addresses to customer equipment. The
latter point means less pressure on IPv4 addresses in a high-growth
environment. This document is not an Internet Standards Track
specification; it is published for informational purposes.
