IPv4

  • 6rd is used to provide IPv6 connectivity services through IPv4-only infrastructure (6 over 4 tunnel)

  • The 6rd CPE uses extended 6rd DHCP option to discover 6rd border relay and to configure IPv6 prefix and address

  • In some fixed line broadband network scenarios, the Broadband Network Gateways (BNGs) act as the access gateway of users (hosts or CPEs). The BNGs also embed a DHCP server function to propagate the user configuration information.

  • User configuration information may be managed by AAA servers. Between AAA servers and BNG, radius protocol is used to carry information.

  • In 6rd deployment, the 6rd user configuration information is also stored in AAA servers. A new RADIUS attribute is needed to propagate these information from AAA servers to BNGs.

6rd Attribute in Radius imitates from the 6rd DHCP option, sub-options are all the same.
