OSPF
----
:abbr:`OSPF (Open Shortest Path First)` is a routing protocol for Internet
Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls
into the group of interior gateway protocols (IGPs), operating within a single
autonomous system (AS). It is defined as OSPF Version 2 in :rfc:`2328` (1998)
for IPv4. Updates for IPv6 are specified as OSPF Version 3 in :rfc:`5340`
(2008). OSPF supports the :abbr:`CIDR (Classless Inter-Domain Routing)`
addressing model.
OSPF is a widely used IGP in large enterprise networks.
OSPFv2 (IPv4)
^^^^^^^^^^^^^
In order to have a VyOS system exchanging routes with OSPF neighbors, you will
at least need to configure the area and a network,
.. code-block:: none
set protocols ospf area 0 network 192.168.0.0/24
as well as the router ID.
.. code-block:: none
set protocols ospf parameters router-id 10.1.1.1
That is the minimum configuration you will need.
Below you can see a typical configuration using 2 nodes, redistribute loopback
address and the node 1 sending the default route:
**Node 1**
.. code-block:: none
set interfaces loopback lo address 10.1.1.1/32
set protocols ospf area 0 network 192.168.0.0/24
set protocols ospf default-information originate always
set protocols ospf default-information originate metric 10
set protocols ospf default-information originate metric-type 2
set protocols ospf log-adjacency-changes
set protocols ospf parameters router-id 10.1.1.1
set protocols ospf redistribute connected metric-type 2
set protocols ospf redistribute connected route-map CONNECT
set policy route-map CONNECT rule 10 action permit
set policy route-map CONNECT rule 10 match interface lo
**Node 2**
.. code-block:: none
set interfaces loopback lo address 10.2.2.2/32
set protocols ospf area 0 network 192.168.0.0/24
set protocols ospf log-adjacency-changes
set protocols ospf parameters router-id 10.2.2.2
set protocols ospf redistribute connected metric-type 2
set protocols ospf redistribute connected route-map CONNECT
set policy route-map CONNECT rule 10 action permit
set policy route-map CONNECT rule 10 match interface lo
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 Phabricator task 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'
