-
-Create a virtual network with [az network vnet create](/cli/azure/network/vnet#az-network-vnet-create). The following example creates a virtual network named **vnet-1** with the address prefix **10.0.0.0/16**.
-
-```azurecli-interactive 
-az network vnet create \
-    --name vnet-1 \
-    --resource-group test-rg \
-    --address-prefixes 10.0.0.0/16 \
-    --subnet-name subnet-1 \
-    --subnet-prefix 10.0.0.0/24
-```
-
-Create the Bastion subnet with [az network vnet subnet create](/cli/azure/network/vnet/subnet).
-
-```azurecli-interactive
-# Create a bastion subnet.
-az network vnet subnet create \
-    --vnet-name vnet-1 \
-    --resource-group test-rg \
-    --name AzureBastionSubnet \
-    --address-prefix 10.0.1.0/24
-```
-
-Create a public IP address for the Azure Bastion host with [az network public-ip create](/cli/azure/network/public-ip). The following example creates a public IP address named *public-ip-bastion* in the *vnet-1* virtual network.
-
-```azurecli-interactive
-az network public-ip create \
-    --resource-group test-rg \
-    --name public-ip-bastion \
-    --location eastus2 \
-    --allocation-method Static \
-    --sku Standard
-```
-
-Create an Azure Bastion host with [az network bastion create](/cli/azure/network/bastion). The following example creates an Azure Bastion host named *bastion* in the *AzureBastionSubnet* subnet of the *vnet-1* virtual network. Azure Bastion is used to securely connect Azure virtual machines without exposing them to the public internet.
-
-```azurecli-interactive
-az network bastion create \
-    --resource-group test-rg \
-    --name bastion \
-    --vnet-name vnet-1 \
-    --public-ip-address public-ip-bastion \
-    --location eastus2 \
-    --sku Basic \
-    --no-wait
-```
-
-```azurecli-interactive
-az network vnet create \
-    --name vnet-2 \
-    --resource-group test-rg \
-    --address-prefixes 10.1.0.0/16 \
-    --subnet-name subnet-1 \
-    --subnet-prefix 10.1.0.0/24
