The IPv6 applications for 7210 SAS are:
IPv6 inband management of the node using network port IPv6 IP interface
IPv6 transit traffic (using network port IPv6 IP interfaces)
Examples of the IPv6 applications supported by the -TiMOS include:
IPv6 Internet exchange peering
The following figure shows an IPv6 Internet exchange where multiple ISPs peer over native IPv6.

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. The 7210 SAS 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. The following figure shows IPv6 over IPv4 tunneling to transition from IPv4 to IPv6.
