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!
