Hi
Just been set up with ISP provided v6 and I'm figuring out dealing with dhcpv6-pd assigned space.

My question:

If I've been assigned 2001:dead:beef:cafe:ff00::/56 and I would like my 1st bridge interface to always get the 1st address on the 1st prefix /64 - i.e.: 2001:dead:beef:cafe:ff01::1/64

Do I do something like
add address=::1:0:0:0:1 from-pool=o2-dynpool interface=MyLan

It doesn't seem to work - is there something I'm missing?

According to docs from AN other router manufacturer this is technically possible- eg
interface FastEthernet 0/1/0
description local network 1
ipv6 address prefix-from-provider ::01:0:0:0:100/64

Thanks in advance
Ben

No, having a subnet hint does not work. There are a number of grumbles about this in other forum posts.

RouterOS only allows to customize Interface ID, but it will pick Subnet ID for you.

OK, thanks for clarifying.. looks like Vyos can't either.

My experience is that the addresses are requested/assigned in the order you created them, and this is the same every time.
In my case that results in the first interface getting :1: at my ISP, but when I use the same config behind an AVM router it gets :fc:.
So no, no direct influence on what subnet number you get, but no real issue either as it does not appear to become "dynamic".

Correction - Vyos can
