Provisioning Multiple Egress IP Addresses in AKS

Hi junpark1135, thanks for reaching out. If you're using CNI with Overlay, you have a single subnet for all the node pools. You then have separate subnets for the pods, so as shown in the diagram, you will have one "default" subnet for pods to be provisioned into (including system pods), and then an additional pod subnet for each application/group of applications that need their own egress IP address. Each additional pod subnet will be associated with an additional NAT Gateway for egress, which is where the different egress IP address comes from. Hope that helps clarify things?
