+=======================
+
+NAME

+-----------
+This type writes the configuration for an instance of the BGP protocol to be
+ran by the bird internet routing daemon. It **expects** to depend on the
+`cdist-type__bird_core(7)` type.
+
+
+REQUIRED PARAMETERS
+-------------------
+local-as
+    The number for the AS in which the daemon is running.
+
+neighbor-as
+    The number of the AS with which we are peering.
+
+neighbor-ip
+    The IP address of the peer we are opening a session with.
+
+
+OPTIONAL PARAMETERS
+-------------------
+description
+    An instance desciption to be printed when `birdc show protocols` is called.
+
+local-ip
+    The IP address used as a source address for the BGP session.
+
+password
+    A password for the BGP session.
+
+ipv4-import
+    A string suitable for the bird `import` directive. Usually `all`, `none` or
+    a filter definition.
+
+ipv4-export
+    See ipv4-import.
+
+ipv4-extended-next-hop
+    Allow IPv6 next hop in IPv4 NLRI.
+
+ipv6-import

+
+ipv6-export
+    See ipv4-import.

+
+BOOLEAN PARAMETERS
+------------------
+direct
+    Specify that the two routers are directly connected.
+
+

+--------
+
+.. code-block:: sh
+
+    # Setup bird and open a BGP session.
+    __bird_core --router-id 198.51.100.4

+    require='__bird_core' __bird_bgp bgp4 \
+        --description "a test IPv4 BGP instance" \
+        --ipv4-export all \
+        --ipv4-import all \
+        --ipv6-export none \
+        --ipv6-import none \

+cdist-type__bird-core(7)
+========================
+
+NAME
+----
+cdist-type__bird-core - setup a skeleton bird configuration.
+
+
+DESCRIPTION
+-----------
+The `bird`_ daemon is an internet routing daemon, running protocols such as
+OSPF and BGP. This type creates a skeleton configuration file suitable for
+running a no-op bird. It is then intended to be combined - and depended on - by
+types specific to the instances of the various protocols that bird should run.
+
+.. _bird: https://bird.network.cz/
+
+OPTIONAL PARAMETERS
+-------------------
+router-id
+    This parameter follows the format of an IPv4 address, and will be used by
+    bird as its router id. See `the documentation for router id`_.
+
+.. _the documentation for router id: https://bird.network.cz/?get_doc&v=20&f=bird-3.html#opt-router-id
+
+log-params
+
+    This parameter expects a string suitable to follow the `log` bird
+    configuration key. If this parameter is not include, the value `syslog all`
+    is used. See `the documentation for log`_.
+
+.. _the documentation for log: https://bird.network.cz/?get_doc&v=20&f=bird-3.html#opt-log
+
+
+EXAMPLES
+--------

+cdist-type__bird_filter(7)
+==========================
+
+NAME
+----
+cdist-type__bird_filter - Create a named filter to use in configuring bird.
+
+
+DESCRIPTION
+-----------
+This type writes a configuration file defining a filter named `__object_id` for
+the bird internet routing daemon. It is guaranteed that all filters defined
+through this type will be loaded before any other protocol defined using the
+cdist __bird_xxx types, except functions. However, note that if two filters
+have a dependency, they will be loaded in alphabetical order, so some care may
+need to be taken in the naming.
+
+This type takes it's input through stdin, expecting valid filter statements as
+per the bird configuration file syntax. The standard input will be printed out
+between a `filter __object_id {\n ... \n}`, so only the inner statements are
+needed.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Setup bird, a filter and open a BGP session.
+    __bird_core --router-id 198.51.100.4
+
+    require='__bird_core' __bird_filter bgp_export <<- EOF
+        if (source = RTS_DEVICE) then accept;
+        reject;
+    EOF
+
+    require='__bird_core' __bird_bgp bgp4 \
+        --description "a test IPv4 BGP instance" \
+        --ipv4-export "filter bgp_export" \

+cdist-type__bird_function(7)
+============================
+
+NAME
+----
+cdist-type__bird_function - Create a named function to use in configuring bird.
+
+
+DESCRIPTION
+-----------
+
+This type writes a configuration file for the bird internet routing daemon. It
+is guaranteed that all functions defined through this type will be loaded
+before any other protocol defined using the cdist __bird_xxx types. However,
+note that if two functions have a dependency, they will be loaded in
+alphabetical order, so some care may need to be taken in the naming.
+
+This type takes it's input through stdin, expecting a valid function definition
+as per the bird configuration file syntax.
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Setup bird, a function and open a BGP session.
+    __bird_core --router-id 198.51.100.4
+
+    require='__bird_core' __bird_function is_device <<- EOF
+        function is_device (enum source)
+        {
+        if (source = RTS_DEVICE) then return true;
+        return false;
+        }
+    EOF

+cdist-type__bird_kernel(7)
+==========================
+
+NAME
+----
+cdist-type__bird_kernel - configure syncing of routes with the kernel.
+
+
+DESCRIPTION
+-----------
+
+This type writes the configuration for an instance of the kernel protocol to be
+ran by the bird internet routing daemon. It **expects** to depend on the
+`cdist-type__bird_core(7)` type.
+
+OPTIONAL PARAMETERS
+-------------------
+description
+    An instance desciption to be printed when `birdc show protocols` is called.
+
+persist
+    Instruct bird to leave routes in kernel table after exiting. See the bird
+    `persist` keyword.
+
+learn
+    Learn routes added externally to the kernel routing table. See the bird
+    `learn` keyword.
+
+channel
+    The channel to connect the protocol to. Usually `ipv4` or `ipv6`.
+
+import
+    A string suitable for the bird `import` directive. Usually `all`, `none` or
+    a filter definition.
+
+export
+    See import.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Setup bird and open a BGP session.
+    __bird_core --router-id 198.51.100.4
+
+    require='__bird_core' __bird_kernel k4 \

+========================
+
+NAME
+----
+cdist-type__bird-ospf - Configure an instance of the OSPF protocol
+
+
+DESCRIPTION
+-----------
+
+This type is an *extremely rudimentary* method to configure a simple OSPF
+protocol instance for bird, the internet routing daemon. Even this manpage is
+pretty crude and will be fixed and expanded.
+
+REQUIRED PARAMETERS
+-------------------
+channel
+    The channel the protocol should connect to. Usually `ipv4` or `ipv6`.
+
+import
+    The keyword or filter to decide what to import in the above channel.
+
+export
+    The keyword or filter to decide what to export in the above channel.
+
+
+REQUIRED MULTIPLE PARAMETERS
+----------------------------
+interface
+    An interface to include in OSPF area 0.
+
+OPTIONAL PARAMETERS
+-------------------
+description
+    A description given with `show protocol all`
+
+instance-id
+    An OSPF instance ID, allowing several OSPF instances to run on the same
+    links.

+cdist-type__bird_static(7)
+==========================
+
+NAME
+----
+cdist-type__bird_static - configure an instance of the bird static protocol.
+
+
+DESCRIPTION
+-----------
+This type write the configuration file for an instance of the static protocl to
+be ran bu the bird internet routing daemon, allowing an administrator to inject
+static routes into the daemon's routing tables. This protocol allows for only
+one of two channels to be used, either `ipv4` or `ipv6`, by default `ipv6` is
+used unless the `ipv4` flag is passed. This type **expects** to depend on the
+`cdist-type__bird_core(7)` type.
+
+
+REQUIRED MULTIPLE PARAMETERS
+----------------------------
+route
+    This flag expects a valid route to be inserted between the bird `route`
+    keyword and the end of line. It may be specified as many times as necessary.
+
+
+OPTIONAL PARAMETERS
+-------------------
+description
+    An instance desciption to be printed when `birdc show protocols` is called.
+
+BOOLEAN PARAMETERS
+------------------
+ipv4
+   Use the ipv4 channel instead of the default ipv6 one.
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Setup bird and open a BGP session.
+    __bird_core --router-id 198.51.100.4
+
+    require='__bird_core' __bird_static static4 \
+        --description "static ipv4 routes plugged into bird" \
+        --route "198.51.0.0/16 via 192.51.100.1" \
+        --route "192.52.0.0/16 via 192.51.100.1"
