MX High-Availability Pair IPv6 Support

[janic]

I've just read that the MX doesn't support IPv6 in a warm spare topology, does anyone actually know if this is a technical issue or has it just not been implemented yet? IPv6 implementation seems to be a slow process, and it would be nice to move towards IPv6 at some point. It's been supported in a 'single MX' topology for about two years now (MX 17.5), just kind of weird to let the well-prepared customers wait so long.

High-availability (HA) and template deployments are not supported at this time.

At the moment there is no support, I believe it is not a limitation but I believe it is because the need was not seen at that time.

Leave your feedback to Meraki and who knows, they might grant your wish.

Will do, let's hope!

I to would love this.  I have only been able to enable IPv6 at small customers and spokes as a result of this.

With the ISP we use, we get a block of IPv4 addresses (/29) and use NAT.  With IPv6 we get a device address (/128) and a block that goes behind it for use in our LAN (/48).  I'm not sure how you'd apply that to an HA pair, but perhaps I'm missing something obvious!

Lack of IPv6 support in warm-spare topology has been blocking us from deploying IPv6 on all of our networks for 2 years.

Yes, this is starting to become a limitation for us in Norway as public sector is required to support IPv6 on their edges and bring IPv6 connectivity to inside client networks as of 01.01.25.  If HA is not supported Meraki will be disqualified in some public sector tenders.

Any new updates on this IPv6 HA topic? At least is there a roadmap when we can expect this functionality.

We are deploying MX HA configuration and we are hitting this issue within our project.
