Azure Internal Load balancer for windows Always-on WSFC name on Azure VM

Hi Team,

While configuring SQL Always-on setup on Azure VM's, we configure an Azure Internal Load balancer with a probe port for a virtual IP and configuring and connecting to SQL listener name, by following a standard procedure (adding listener name through cluster manager and running few powershell scripts on cluster to bound probe port and virtual IP).

As we do not use windows WSFC name for connecting to Databases, do we need to configure an Azure Internal Load balancer with a probe port for windows Always-on WSFC virtual ip as well?

What kind of issues we may face during failover if we have configured internal load balancer for SQL listener virtual IP but not for WSFC virtual IP?

Thanks.

Best Regards,
