Abstract

This memo specifies the frame format for transmission of IPv6 [IPV6] packets and the method of forming IPv6 link-local addresses over IPv4 domains. It also specifies the content of the Source/Target Link- layer Address option used in the Router Solicitation, Router Advertisement, Neighbor Solicitation, and Neighbor Advertisement and Redirect messages, when those messages are transmitted on an IPv4 multicast network.

Abstract

This memo specifies the frame format for transmission of IPv6 [IPV6]

packets and the method of forming IPv6 link-local addresses over IPv4

domains. It also specifies the content of the Source/Target Link-

layer Address option used in the Router Solicitation, Router

Advertisement, Neighbor Solicitation, and Neighbor Advertisement and

Redirect messages, when those messages are transmitted on an IPv4

multicast network.

The motivation for this method is to allow isolated IPv6 hosts,

located on a physical link which has no directly connected IPv6

router, to become fully functional IPv6 hosts by using an IPv4 domain

that supports IPv4 multicast as their virtual local link. It uses

IPv4 multicast as a "virtual Ethernet".
