Plugins Sysrepo
===============
Installation
------------
Required dependencies
^^^^^^^^^^^^^^^^^^^^^
Install FRR build required dependencies, check `Building FRR
<https://docs.frrouting.org/projects/dev-guide/en/latest/building.html>`_ document for specific platform required packages.
Below are debian systems required packages:
.. code-block:: console
sudo apt-get install git autoconf automake libtool make \
libprotobuf-c-dev protobuf-c-compiler build-essential \
python3-dev python3-pytest python3-sphinx libjson-c-dev \
libelf-dev libreadline-dev cmake libcap-dev bison flex \
pkg-config texinfo gdb libgrpc-dev python3-grpc-tools libpcre2-dev
libyang
^^^^^^^
.. note::
FRR requires version 2.1.128 or newer, in this document we will
be compiling and installing libyang version 2.1.148.
.. code-block:: console
git clone https://github.com/CESNET/libyang.git
cd libyang
git checkout v2.1.148
mkdir build; cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr \
-DCMAKE_BUILD_TYPE:String="Release" ..
make
sudo make install
Sysrepo
^^^^^^^
.. note::
The following code block assumes you have installed libyang v2.1.148, if you have
libyang v2.1.128 change sysrepo version to 2.2.105.
.. code-block:: console
git clone https://github.com/sysrepo/sysrepo.git
cd sysrepo/
git checkout v2.2.150
mkdir build; cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr \
-DCMAKE_BUILD_TYPE:String="Release" ..
make
sudo make install
Verify that sysrepo is installed correctly:
.. code-block:: console
sudo sysrepoctl -l
FRR
^^^
Follow the steps of `Building FRR
<https://docs.frrouting.org/projects/dev-guide/en/latest/building.html>`_
Make sure to use ``--enable-sysrepo`` configure-time option while building FRR.
Below is an example of frr configure-time options, your options
might vary, however in order to allow sysrepo plugin you have
to keep ``--enable-sysrepo`` option:
.. code-block:: console
./bootstrap.sh
./configure \
--localstatedir=/var/opt/frr \
--sbindir=/usr/lib/frr \
--sysconfdir=/etc/frr \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--enable-configfile-mask=0640 \
--enable-logfile-mask=0640 \
--enable-fpm \
--enable-sysrepo \
--with-pkg-git-version \
--with-pkg-extra-version=-MyOwnFRRVersion
make
make check
sudo make install
Initialization
--------------
Install FRR YANG modules in Sysrepo datastore:
.. code-block:: console
cd frr/yang/
sudo sysrepoctl -i ./ietf/ietf-interfaces.yang -o frr -g frr
sudo sysrepoctl -i frr-vrf.yang -o frr -g frr
sudo sysrepoctl -i frr-interface.yang -o frr -g frr
sudo sysrepoctl -i frr-route-types.yang -o frr -g frr
sudo sysrepoctl -i frr-filter.yang -o frr -g frr
sudo sysrepoctl -i frr-route-map.yang -o frr -g frr
sudo sysrepoctl -i frr-isisd.yang -o frr -g frr
sudo sysrepoctl -i frr-bfdd.yang -o frr -g frr
sudo sysrepoctl -i ./ietf/ietf-routing-types.yang -o frr -g frr
sudo sysrepoctl -i frr-nexthop.yang -o frr -g frr
sudo sysrepoctl -i frr-if-rmap.yang -o frr -g frr
sudo sysrepoctl -i frr-ripd.yang -o frr -g frr
sudo sysrepoctl -i frr-ripngd.yang -o frr -g frr
sudo sysrepoctl -i frr-affinity-map.yang -o frr -g frr
sudo sysrepoctl -i ./ietf/frr-deviations-ietf-interfaces.yang -o frr -g frr
Start FRR daemons with sysrepo plugin:
.. code-block:: console
sudo /usr/lib/frr/isisd -M sysrepo --log stdout
Any daemon running with ``-M sysrepo`` will subscribe to its frr yang moduels
on sysrepo and you be able to configure it by editing module configuration on sysrepo.
Managing the configuration
--------------------------
Testing
^^^^^^^
To test FRR intergartion with sysrepo, ``sysrepocfg`` tool can be used
to edit frr configuration on sysrepo
Example:
Edit sysrepo running datastore configuration for the desiged frr module:
.. code-block:: console
sudo sysrepocfg -E nano -d running -m frr-isisd -f json
Paste the following json configuration:
.. code-block:: console
{
"frr-isisd:isis": {
"instance": [
{
"area-tag": "testnet",
"vrf": "default",
"is-type": "level-1"
}
]
}
}
Exit and save config to the same file.
After that, this configuration should get reflected to vtysh:
.. code-block:: console
show run
Building configuration...
Current configuration:
!
frr version 9.2-dev-MyOwnFRRVersion
frr defaults traditional
hostname bullseye
!
router isis testnet
is-type level-1
exit
!
end
NETCONF
^^^^^^^
To manage sysrepo configuration through netconf
you can use `netopeer2 <https://github.com/CESNET/netopeer2>`_ as a netfconf server that can
be easily integrated with sysrepo.
