+# incus_network_integration
+
+Manage integrations between the local Incus deployment and remote networks hosted on Incus or other platforms. Currently available only for [OVN networks](https://linuxcontainers.org/incus/docs/main/reference/network_ovn/#network-ovn).
+
+## Basic Example
+
+```hcl
+resource "incus_network_integration" "this" {
+    name   = "ovn-region"
+    type   = "ovn"
+
+    config = {
+        "ovn.northbound_connection" = "tcp:[192.0.2.12]:6645,tcp:[192.0.3.13]:6645,tcp:[192.0.3.14]:6645"
+        "ovn.southbound_connection" = "tcp:[192.0.2.12]:6646,tcp:[192.0.3.13]:6646,tcp:[192.0.3.14]:6646"
+    }
+}
+```
+
+## Peer Example
+
+```hcl
+resource "incus_network" "default" {
+  name = "default"
+  type = "ovn"
+
+  config = {
+    "ipv4.address" = "192.168.2.0/24"
+    "ipv4.nat"     = "true"
+  }
+}
+
+resource "incus_network_integration" "this" {
+    name   = "ovn-region"
+    type   = "ovn"
+
+    config = {
+        "ovn.northbound_connection" = "tcp:[192.0.2.12]:6645,tcp:[192.0.3.13]:6645,tcp:[192.0.3.14]:6645"
+        "ovn.southbound_connection" = "tcp:[192.0.2.12]:6646,tcp:[192.0.3.13]:6646,tcp:[192.0.3.14]:6646"
+    }
+}
+
+resource "incus_network_peer" "this" {
+    name               = "ovn-peer"
+    network            = incus_network.default.name
+    target_integration = incus_network_integration.this.name
+}
+```
