-## Enable the AGIC add-on in existing AKS cluster through Azure portal 
-
-If you'd like to use Azure portal to enable AGIC add-on, go to [(https://aka.ms/azure/portal/aks/agic)](https://aka.ms/azure/portal/aks/agic) and navigate to your AKS cluster through the portal link. From there, go to the Networking tab within your AKS cluster. You'll see an application gateway ingress controller section, which allows you to enable/disable the ingress controller add-on using the Azure portal. Select the box next to **Enable ingress controller**, and then select the application gateway you created, **myApplicationGateway** from the dropdown menu. Select **Save**.
-
 > [!IMPORTANT]
 > When you use an application gateway in a different resource group than the AKS cluster resource group, the managed identity **_ingressapplicationgateway-{AKSNAME}_** that is created must have **Contributor** and **Reader** roles set in the application gateway resource group.

 ## Peer the two virtual networks together
 
 Since you deployed the AKS cluster in its own virtual network and the Application gateway in another virtual network, you'll need to peer the two virtual networks together in order for traffic to flow from the Application gateway to the pods in the cluster. Peering the two virtual networks requires running the Azure CLI command two separate times, to ensure that the connection is bi-directional. The first command will create a peering connection from the Application gateway virtual network to the AKS virtual network; the second command will create a peering connection in the other direction.
