DHCPv6 reservation v7.4.6

Hi,

I have a fortigate and managed fortiswitchs.
FG 80f version is v7.4.6
Fortiswitch 148f is v7.2.4

I have setup DHCPv6 on a VLAN and my devices are getting IPv6 addresses from DHCPv6.

I would like to reserve one of the devices so it will always receive the same IPv6 address.

I was unable to find a way to do it with IPv6. I do have the option to do it with IPv4.

Hi @Anonymous_User ,

It seems that there is no Reservation Address for DHCP6.

@dingjerry_FTNT Thank you for your reply.

does it exist on newer firmware versions?
Any plans to add it?

Hi @Anonymous_User ,

DHCP6 has stateless and stateful 2 modes.

The Reservation Address is possible with the Stateful mode only and it is not based on MAC address. It should use DUID for it.

Please check RFC 8415 & RFC 6355 for more information.

I have no info about this feature in the new versions.

@dingjerry_FTNT Thank you, would you be able to provide some guidance on how to set it up?
I have set the DHCPv6 as stateful already
