How do I configure CDRouter for DHCPv6 prefix delegation?
IPv6Starting with CDRouter 6.2, the CDRouter IPv6 add-on supports DHCPv6 prefix delegation on the WAN.
DHCPv6 prefix delegation can be enabled when the testvar ipv6WanMode is set to DHCP, static, PPPoE, or autoconf. The prefix and prefix length provided by CDRouter's DHCPv6 server on the WAN are specified by the testvars dhcpv6WanAssignPrefix and dhcpv6WanAssignPrefixLen. The testvar dhcpv6WanAssignNextPrefix specifies a free prefix on the WAN used for renumbering tests. The testvar dhcpv6PDLatency defines the amount of time, in seconds, it takes the DUT to update its LAN side IPv6 settings when a new IPv6 prefix is learned on the WAN.
Example Configuration
testvar dhcpv6WanEnablePD yes testvar dhcpv6WanAssignPrefix 3001:dddd:: testvar dhcpv6WanAssignNextPrefix 3001:ddde:: testvar dhcpv6WanAssignPrefixLen 48 testvar dhcpv6PDLatency 30
