IPv6 over IPv4 relay services — IPv6 over IPv4 tunnels are one of many IPv6 transition
methods to support IPv6 in an environment where not only IPv4 exists but native IPv6
networks depend on IPv4 for greater IPv6 connectivity. Alcatel-Lucent router supports
dynamic IPv6 over IPv4 tunneling. The ipv4 source and destination address are taken from
configuration, the source address is the ipv4 system address and the ipv4 destination is the
next hop from the configured 6over4 tunnel.
IPv6 over IPv4 is an automatic tunnel method that gives a prefix to the attached IPv6
network.

shows IPv6 over IPv4 tunneling to transition from IPv4 to IPv6.
