Deploy an IPv6 dual stack application with Basic Load Balancer in Azure - Template

This article provides a list of IPv6 configuration tasks with the portion of the Azure Resource Manager VM template that applies to. Use the template described in this article to deploy a dual stack (IPv4 + IPv6) application with Basic Load Balancer that includes a dual stack virtual network with IPv4 and IPv6 subnets, a Basic Load Balancer with dual (IPv4 + IPv6) front-end configurations, VMs with NICs that have a dual IP configuration, network security group, and public IPs.

To deploy a dual stack (IPV4 + IPv6) application using Standard Load Balancer, see Deploy an IPv6 dual stack application with Standard Load Balancer - Template.

Required configurations

Search for the template sections in the template to see where they should occur.

Conditional configuration

If you're using a network virtual appliance, add IPv6 routes in the Route Table. Otherwise, this configuration is optional.

            "name": "v6route",
            "properties": {
              "addressPrefix": "fd00:db8:deca:deed::/64",
              "nextHopType": "VirtualAppliance",
