[Feature] AKS Automatic support for Dual stack networking [IPv6]

Open SatyKrish opened this issue 10 months ago • 1 comments

Is your feature request related to a problem? Please describe. AKS Automatic sku doesn't support ipv6 ip family, although standard AKS cluster on CNI overlay with Cilium supports dual-stack networking.

Describe alternatives you've considered Using a standard AKS cluster on CNI overlay with Cilium supports dual-stack networking.

This is a limitation of Node Auto Provisioning. We'll look into it.

Any updates on dual stack support?
