How many unique dual-stack device configurations can I test with CDRouter IPv6?

IPv6

CDRouter IPv6 currently supports 11 unique IPv6 WAN connection modes, two IPv6 LAN modes, and seven IPv4 WAN connection modes, resulting in over 100 unique dual-stack CPE configurations that can be tested.

The following table provides a summary of the dual-stack device configurations currently supported by CDRouter IPv6, where "DHCPv6 NA" refers to the use of DHCPv6 for non-temporary address assignment, and "DHCPv6-PD" refers to the use of DHCPv6 for prefix delegation:

IPv4 WAN Mode IPv6 WAN Mode DHCPv6 NA DHCPv6 PD IPv6 LAN Mode
any static not applicable no autoconf or DHCPv6
any static not applicable yes autoconf or DHCPv6
any Ethernet* PPPoE no no autoconf or DHCPv6
any Ethernet* PPPoE yes yes autoconf or DHCPv6
any Ethernet* PPPoE no yes autoconf or DHCPv6
any 6to4 not applicable not applicable autoconf or DHCPv6
any 6rd not applicable not applicable autoconf or DHCPv6
any autoconf not applicable no autoconf or DHCPv6
any autoconf not applicable yes autoconf or DHCPv6
any DHCP not applicable** no autoconf or DHCPv6
any DHCP not applicable** yes autoconf or DHCPv6
* PPPoE requires an Ethernet physical layer. As a result, IPv4 WAN modes of PPP/T1 and PPPoA are not compatible with IPv6 over PPPoE configurations.
** When the testvar ipv6WanMode is set to DHCP, DHCPv6 is implicitly used for non-temporary address assignment. The testvar dhcpv6WanEnableNA has no impact.
