+# Data Source: azurerm_private_dns_resolver_virtual_network_link
+
+Gets information about an existing Private DNS Resolver Virtual Network Link.
+
+## Example Usage
+
+```hcl
+data "azurerm_private_dns_resolver_virtual_network_link" "example" {
+  name                      = "example-link"
+  dns_forwarding_ruleset_id = "example-dns-forwarding-ruleset-id"
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+
+* `name` - (Required) Name of the Private DNS Resolver Virtual Network Link.
+
+* `dns_forwarding_ruleset_id` - (Required) ID of the Private DNS Resolver DNS Forwarding Ruleset.
+
+## Attributes Reference
+
+In addition to the Arguments listed above - the following Attributes are exported:
+
+* `id` - The ID of the Private DNS Resolver Virtual Network Link.
+
+* `virtual_network_id` - The ID of the Virtual Network that is linked to the Private DNS Resolver Virtual Network Link.
+
+* `metadata` - The metadata attached to the Private DNS Resolver Virtual Network Link.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/language/resources/syntax#operation-timeouts) for certain actions:
+
+* `read` - (Defaults to 5 minutes) Used when retrieving the Private DNS Resolver Virtual Network Link.
