In order to make a graceful IPv4 sunset, this memo described a method helping traffic migration to IPv6. With the growth of IPv6 traffic, operators could safely turn off IPv4 and evolve to IPv6-only network. In order to achieve the goal, new traffic-migration options have been proposed in DHCPv6 and PCP. IPv6 traffic steering could be performed using those configurations.
