Description

We have a requirement to specify predictable IP addresses for the routers created as part of the virtual hub. Based on the azurerm_virtual_hub documentation It is possible to specify the IP prefix used by the virtual hub, but not the IP addresses of the routers created within that prefix.

According to the Microsoft.Network/virtualHubs reference it is possible to specify the router IPs in the properties.virtualRouterIps field, however I haven't tested this myself, and I note the Azure CLI doesn't allow specifying these IP addresses either, so don't know what is actually possible.

  name                = "virtual-hub-01"
  resource_group_name = "virtual-wan-rg"
  virtual_wan_id      = azurerm_virtual_wan.vwan.id
  virtual_router_ips  = ["10.1.1.1", "10.1.1.2"]
}
