This parameter specifies the host identifier portion of the first IPv6 address in the DUT’s DHCPv6 address pool. This value should match the value configured on the DUT.
CDRouter will automatically determine the correct prefix for this address based on the IPv6 WAN mode being used. If the IPv6 WAN mode is “6to4”, CDRouter will use the expected 6to4 prefix for the prefix portion of the DHCPv6 address pool. If the IPv6 WAN mode is “static”, CDRouter will calculate the IPv6 prefix based on the IPv6 LAN IP and prefix length.
In bridge mode configurations, this testvar must be a full IPv6 address within the same network as the WAN network ipv6WanIspIp/ipv6WanIspPrefixLen.
