IPv6

DHCPv6 server is configurable in delegated mode (295007)

Downstream IPv6 interfaces can receive address assignments on delegated subnets from a DHCP server that serves an upstream interface.

DHCPv6-PD configuration

Enable DHCPv6 Prefix Delegation on upstream interface (port10):

config system interface edit “port10”

config ipv6

set dhcp6-prefix-delegation enable end

end

Assign delegated prefix on downstream interface (port1). Optionally, specific delegated prefixes can be specified:

config system interface edit “port1”

config ipv6

set ip6-mode delegated

set ip6-upstream-interface “port10” set ip6-subnet ::1:0:0:0:1/64

set ip6-send-adv enable

config ipv6-delegated-prefix-list edit 1

set upstream-interface “port10” set autonomous-flag enable

set onlink-flag enable

set subnet 0:0:0:100::/64 end

end end

DHCPv6 Server configuration

Configuring a server that uses delegated prefix and DNS from upstream:

config system dhcp6 server edit 1

set dns-service delegated set interface “wan2”

set upstream-interface “wan1” set ip-mode delegated

set subnet 0:0:0:102::/64 end
