Default Value

This testvar must be explicitly defined in the configuration file


This parameter specifies the DUT’s statically configured 6rd prefix. This parameter is represented as a 16 octet IPv6 address with all bits following the 6rd prefix length set to 0.

Some 6rd configuration examples:

Private WAN IPv4 Address

WAN IPv4 Address: 6rd Prefix: 2010:1234:: 6rd Prefix Length: 32 6rd IPv4 Mask Length: 8 6rd Delegated Prefix: 2010:1234:A8C8:0200:/56

Public WAN IPv4 Address

WAN IPv4 Address: 6rd Prefix: 2010:: 6rd Prefix Length: 16 6rd IPv4 Mask Length: 0 6rd Delegated Prefix: 2010:0C0C:0C02::/48

Note that stateless address autoconfiguration (autoconf) requires an IPv6 prefix less than or equal to 64 bits. The test run will be aborted if autoconf is used on the LAN and the DUT provides a 6rd prefix greater than 64 bits in length.
