+OSPFv3 (IPv6)
+#############
+
+A typical configuration using 2 nodes.
+
+**Node 1:**
+
+.. code-block:: none
+
+  set protocols ospfv3 area 0.0.0.0 interface eth1
+  set protocols ospfv3 area 0.0.0.0 range 2001:db8:1::/64
+  set protocols ospfv3 parameters router-id 192.168.1.1
+  set protocols ospfv3 redistribute connected
+
+**Node 2:**
+
+.. code-block:: none
+
+  set protocols ospfv3 area 0.0.0.0 interface eth1
+  set protocols ospfv3 area 0.0.0.0 range 2001:db8:2::/64
+  set protocols ospfv3 parameters router-id 192.168.2.1
+  set protocols ospfv3 redistribute connected
+
+.. note:: You can not easily redistribute IPv6 routes via OSPFv3 on a WireGuard
+   interface link. This requires you to configure link-local addresses manually
+   on the WireGuard interfaces, see :vytask:`T1483`.
+
+Example configuration for WireGuard interfaces:
+
+**Node 1**
+
+.. code-block:: none
+
+  set interfaces wireguard wg01 address 'fe80::216:3eff:fe51:fd8c/64'
+  set interfaces wireguard wg01 address '192.168.0.1/24'
+  set interfaces wireguard wg01 peer ospf02 allowed-ips '::/0'
+  set interfaces wireguard wg01 peer ospf02 allowed-ips '0.0.0.0/0'
+  set interfaces wireguard wg01 peer ospf02 endpoint '10.1.1.101:12345'
+  set interfaces wireguard wg01 peer ospf02 pubkey 'ie3...='
+  set interfaces wireguard wg01 port '12345'
+  set protocols ospfv3 parameters router-id 192.168.1.1
+  set protocols ospfv3 area 0.0.0.0 interface 'wg01'
+  set protocols ospfv3 area 0.0.0.0 interface 'lo'
+
+**Node 2**
+
+.. code-block:: none
+
+  set interfaces wireguard wg01 address 'fe80::216:3eff:fe0a:7ada/64'
+  set interfaces wireguard wg01 address '192.168.0.2/24'
+  set interfaces wireguard wg01 peer ospf01 allowed-ips '::/0'
+  set interfaces wireguard wg01 peer ospf01 allowed-ips '0.0.0.0/0'
+  set interfaces wireguard wg01 peer ospf01 endpoint '10.1.1.100:12345'
+  set interfaces wireguard wg01 peer ospf01 pubkey 'NHI...='
+  set interfaces wireguard wg01 port '12345'
+  set protocols ospfv3 parameters router-id 192.168.1.2
+  set protocols ospfv3 area 0.0.0.0 interface 'wg01'
+  set protocols ospfv3 area 0.0.0.0 interface 'lo'
