Dynamic Routing: Configuration: OSPFv2
|
||
======================================
|
||
|
||
-------
|
||
General
|
||
-------
|
||
|
||
.. Warning::
|
||
Saving the settings will apply them and reload the daemon. This means you may lose the connection to your firewall for some seconds.
|
||
|
||
.. image:: images/dynamic_routes_ospf_general.png
|
||
|
||
Enable
|
||
------
|
||
|
||
Enables the OSPF routing daemon.
|
||
If this does not work, please check the settings of General.
|
||
Check this checkbox if you want to use OSPFv2 in your network.
|
||
|
||
Passive Interfaces
|
||
------------------
|
||
|
||
Passive Interfaces are interfaces,
|
||
which exist in OSPFv2 but where no routing updates should be sent to.
|
||
These are usually the Interfaces,
|
||
where your clients are connected to and no router should exist.
|
||
You don‘t need to add interfaces here, where no network is specified.
|
||
|
||
Route Redistribution
|
||
--------------------
|
||
|
||
Route Redistribution is used,
|
||
if you want to send information this router has learned via another protocol
|
||
or routes from kernel (OPNsense static routes).
|
||
|
||
Advertise Default Gateway
|
||
-------------------------
|
||
|
||
Advertise Default Gateway should be checked,
|
||
if this machine has a default gateway to the internet.
|
||
Always Advertise means, that this route should be also broadcasted,
|
||
if it is not available. Be careful with this option in HA setups.
|
||
|
||
--------
|
||
Networks
|
||
--------
|
||
|
||
.. image:: images/dynamic_routes_ospf_networks.png
|
||
|
||
Networks gives you a brief overview of the configured networks. The dialog looks like this:
|
||
|
||
.. image:: images/dynamic_routes_ospf_network_dialog.png
|
||
|
||
Enabled
|
||
-------
|
||
|
||
Enabled means that this Network is going to be used.
|
||
You should only disable networks if you plan to do some changes in your topology or some routes get broken.
|
||
|
||
Network Address
|
||
---------------
|
||
|
||
The Network Address of a local interface on which OSPFv2 should be enabled.
|
||
|
||
Network Mask
|
||
------------
|
||
|
||
A CIDR Mask for the Network Address.
|
||
For example, if your LAN IP is 192.168.0.1/24, the network address is 192.168.0.0 and Network Mask is 24.
|
||
|
||
Area
|
||
----
|
||
|
||
The area describes which routers belong to the same group (autonomous system). This value is a 32 bit integer, which is entered in dotted decimal notation (like an IPv4 address is usually written).
|
||
|
||
Prefix-List in and Out
|
||
----------------------
|
||
|
||
Only used for advanced route filtering using access lists.
|
||
|
||
----------
|
||
Interfaces
|
||
----------
|
||
|
||
This tab shows an overview of the configured interfaces:
|
||
|
||
.. image:: images/dynamic_routes_ospf_interfaces.png
|
||
|
||
.. Note::
|
||
Changes in this view do *NOT* apply the settings.
|
||
|
||
If you add or edit an entry, you will get this dialog:
|
||
|
||
.. image:: images/dynamic_routes_ospf_interface_dialog.png
|
||
|
||
Interface
|
||
---------
|
||
Choose a single interface, where this interface settings apply to.
|
||
|
||
Authentication Type and Authentication Key
|
||
------------------------------------------
|
||
|
||
This values can be set,
|
||
but they are not used as there is no area configuration which would make use of them.
|
||
You may want to set the password here if you add a custom area setting via vtysh.
|
||
|
||
Cost
|
||
----
|
||
|
||
A numeric value to set the cost on an interface.
|
||
The cost is used to calculate the route to the target.
|
||
A bigger value here means, the route is less likely used.
|
||
|
||
Hello and Dead Interval
|
||
-----------------------
|
||
|
||
Hello interval is the interval in which hello packets (detection of other OSPF routers) are sent out.
|
||
A bigger value means sower detection but less load on the interface.
|
||
Dead Interval is the time window, in which the router has to receive a hello packet from another router.
|
||
If it does not, it is removed.
|
||
|
||
Priority
|
||
--------
|
||
|
||
This field specifies the router priority which means a router with a good priority is more probably the designated router.
|
||
Network type usually does not need to be set.
