IPv6 on second VLAN

My ISP Rogers dishes out multiple /64 plus other options like /56 although that may have changed recently. for a long time I was using /64 and assigning to each subnet or vlan.

With Ubiguiti Routers its very easy to do that utilizing a commands like:

set interfaces ethernet eth0 dhcpv6-pd pd 0 interface eth2.10 host-address '::1'
set interfaces ethernet eth0 dhcpv6-pd pd 0 interface eth2.10 'no-dns'
set interfaces ethernet eth0 dhcpv6-pd pd 0 interface eth2.10 service 'slaac'
set interfaces ethernet eth0 dhcpv6-pd pd 0 prefix-length '64'
set interfaces ethernet eth0 dhcpv6-pd pd 1 interface eth2.20 host-address '::1'
set interfaces ethernet eth0 dhcpv6-pd pd 1 interface eth2.20 'no-dns'
set interfaces ethernet eth0 dhcpv6-pd pd 1 interface eth2.20 service 'slaac'
set interfaces ethernet eth0 dhcpv6-pd pd 1 prefix-length '64'
set interfaces ethernet eth0 dhcpv6-pd pd 2 interface eth2.30 host-address '::1'
set interfaces ethernet eth0 dhcpv6-pd pd 2 interface eth2.30 'no-dns'
set interfaces ethernet eth0 dhcpv6-pd pd 2 interface eth2.30 service 'slaac'
set interfaces ethernet eth0 dhcpv6-pd pd 2 prefix-length '64'
set interfaces ethernet eth0 dhcpv6-pd rapid-commit 'enable'

I do not believe that the same can be done using RouterOS …. I could not find the ability to add an index like PD 0, PD 1,PD 2 etc

First you you have to find out from your ISP if they would dish out multiple /64 and if YES then some RouterOS GURU needs to confirm how to convert the above code to RouterOS speak
Ideally, check with your ISP if they will issue a /40 or /60 or /56 … many ISP are going with a /56 for their users — some are only providing that for their business class users and if not some ISP will dole out multiple /64

That’s exactly what my issue is, my ISP AT&T issues out a /60 but to their RG, they then request that my RB4011 make multiple pd requests or multiple DHCPv6_clients to pull several /64s. They will NOT allow my RB4011 to take the /60, only their equipment is allowed control over the /60 sigh.

I guess Ubiquiti is the solution for now since the popular bypass doesn’t work anymore for me (XGS-pon).

I didn’t test it much, but it seems that good old VRRP hack works for DHCPv6 too.

That worked! Thank you for sharing the link, it’s been working well.

Maybe it is time to explain the ISP how to deploy IPv6. Why are they using non-standard “tricks” when there is an established method of doing things?
I just have a DHCPv6 client requesting a prefix, I get a block of addresses in the pool (a /48, the ISPs are not that stingy here), and from there I can assign addresses to interfaces.
That works almost without effort.
