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. Nokia routers support 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 IPv6 over IPv4 tunnel.
IPv6 over IPv4 is an automatic tunnel method that gives a prefix to the attached IPv6 network. Figure: IPv6 over IPv4 tunnels shows IPv6 over IPv4 tunneling to transition from IPv4 to IPv6.
