Unable to Add Basic IPv6 to Network Interface

Question

Hello,

I am trying to make a VM which can receive ICMPv6 messages. Standard SKU does not work because it requires a Network Security Group to accept incoming connections, and NSG does not support ICMPv6. The only other option is to use a Basic SKU Public IP, but when attempting to associate it with the Network Interface I get the error

Failed to update network interface [...]. Error: Cannot specify basic sku PublicIp [...] for an IPv6 network interface ipConfiguration [...].

The only other Public IP associated with this Network Interface is a Basic SKU IPv4 Public IP. How should I add the Public IPv6 so my VM can respond to public ICMPv6 pings?

Thanks in advance.

Hi @aayush,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you are trying to attach an IPv6 Public IP of basic SKU to an Azure VM's Nic.

There are two things to notice here,

1. The co-existence of Basic and Standard SKU Azure resources is not supported with one or two exceptions.
2. Secondly, you will not be able to assign a basic SKU IPv6 to a Network Interface.

• This is an expected behavior
• Basic IPV6 Public IPs can only be associated with Load Balancers to provide support for legacy
• You should create a standard Public IPV6 and associate it with the NIC
• Also, you must upgrade your basic IPV4 to standard, if you are planning to go ahead with the above

I hope this helps.
