-The libyang library can be installed from third-party packages available `here
-<https://ci1.netdef.org/browse/LIBYANG-YANGRELEASE/latestSuccessful/artifact>`_.
+FRR depends on the relatively new ``libyang`` library to provide YANG/NETCONF
+support. Unfortunately, most distributions do not yet offer a ``libyang``
+package from their repositories. Therefore we offer two options to install this
+library.
-Note: the libyang dev/devel packages need to be installed in addition
-to the libyang core package in order to build FRR successfully.
+**Option 1: Binary Install**
+
+The FRR project builds binary ``libyang`` packages, which we offer for download
+`here <https://ci1.netdef.org/browse/LIBYANG-YANGRELEASE/latestSuccessful/artifact>`_.
.. warning::
- libyang ABI version 0.16.74 or newer will be required to build FRR in the
- near future since it significantly eases build and installation
- considerations. "0.16-r3" is equal to 0.16.105 and will work, "0.16-r2"
- is equal to 0.16.52 and will stop working. The CI artifacts will be
- updated shortly.
-For example, for CentOS 7.x:
+ ``libyang`` version 0.16.74 or newer is required to build FRR.
+
+.. note::
-.. code-block:: shell

Packaging Debian
================
--- /dev/null
+.. _packaging-redhat:
+
+Packaging Red Hat
+=================
+
+Tested on CentOS 6, CentOS 7 and Fedora 24.
+
+1. On CentOS 6, refer to :ref:`building-centos6` for details on installing
+ sufficiently up-to-date package versions to enable building FRR.
+
+ Newer automake/autoconf/bison is only needed to build the RPM and is **not**
+ needed to install the binary RPM package.
+
+2. Install the build dependencies for your platform. Refer to the
+ platform-specific build documentation on how to do this.
+
+3. Install the following additional packages::
+
+ yum install rpm-build net-snmp-devel pam-devel libcap-devel
+
+ If your platform uses systemd::
+
+ yum install systemd-devel
+
+ If ``yum`` is not present on your system, use ``dnf`` instead.
+
+3. Checkout FRR::
+
+ git clone https://github.com/frrouting/frr.git frr
+
+4. Run Bootstrap and make distribution tar.gz::
+
+ cd frr
+ ./bootstrap.sh
+ ./configure --with-pkg-extra-version=-MyRPMVersion SPHINXBUILD=sphinx-build2.7
+ make dist
+
+ .. note::
+
+ The only ``configure`` option respected when building RPMs is
+ ``--with-pkg-extra-version``.
+
+5. Create RPM directory structure and populate with sources::
+
+ mkdir rpmbuild
+ mkdir rpmbuild/SOURCES
+ mkdir rpmbuild/SPECS
+ cp redhat/*.spec rpmbuild/SPECS/
+ cp frr*.tar.gz rpmbuild/SOURCES/
+
+6. Edit :file:`rpm/SPECS/frr.spec` with configuration as needed.
+
+ Look at the beginning of the file and adjust the following parameters to
+ enable or disable features as required::
+
+ ############### FRRouting (FRR) configure options #################
+ # with-feature options
+ %{!?with_pam: %global with_pam 0 }
+ %{!?with_ospfclient: %global with_ospfclient 1 }
+ %{!?with_ospfapi: %global with_ospfapi 1 }
+ %{!?with_irdp: %global with_irdp 1 }
+ %{!?with_rtadv: %global with_rtadv 1 }
+ %{!?with_ldpd: %global with_ldpd 1 }
+ %{!?with_nhrpd: %global with_nhrpd 1 }
+ %{!?with_eigrp: %global with_eigrpd 1 }
+ %{!?with_shared: %global with_shared 1 }
+ %{!?with_multipath: %global with_multipath 256 }
+ %{!?frr_user: %global frr_user frr }
+ %{!?vty_group: %global vty_group frrvty }
+ %{!?with_fpm: %global with_fpm 0 }
+ %{!?with_watchfrr: %global with_watchfrr 1 }
+ %{!?with_bgp_vnc: %global with_bgp_vnc 0 }
+ %{!?with_pimd: %global with_pimd 1 }
+ %{!?with_rpki: %global with_rpki 0 }
+
+7. Build the RPM::
+
+ rpmbuild --define "_topdir `pwd`/rpmbuild" -ba rpmbuild/SPECS/frr.spec
+
+ If building with RPKI, then download and install the additional RPKI
+ packages from
+ https://ci1.netdef.org/browse/RPKI-RTRLIB/latestSuccessful/artifact
+
+If all works correctly, then you should end up with the RPMs under
+:file:`rpmbuild/RPMS` and the source RPM under :file:`rpmbuild/SRPMS`.

VTYSH communicates with FRR daemons by way of domain socket. Each daemon
creates its own socket, typically in :file:`/var/run/frr/<daemon>.vty`. The

-Building your own FRRouting RPM
-======================================
-(Tested on CentOS 6, CentOS 7 and Fedora 24.)
-
-1. On CentOS 6 (which doesn't provide a bison/automake/autoconf of a recent enough version):
- - Check out ../doc/developer/building-frr-for-centos6.rst for details on installing
- a bison/automake/autoconf to support frr building.
-
- Newer automake/autoconf/bison is only needed to build the rpm and is
- **not** needed to install the binary rpm package
-
-2. Install the build packages as documented in doc/developer/building-frr-for-xxxxx.rst and the following additional packages:
-
- yum install rpm-build net-snmp-devel pam-devel libcap-devel
-
- Additionally, on systems with systemd (CentOS 7, Fedora)
-
- yum install systemd-devel
-
- (use `dnf install` on new Fedora instead of `yum install`)
-
-3. Checkout FRR under a **unpriviledged** user account
-
- git clone https://github.com/frrouting/frr.git frr
-
-4. Run Bootstrap and make distribution tar.gz
-
- cd frr
- ./bootstrap.sh
- ./configure --with-pkg-extra-version=-MyRPMVersion \
- SPHINXBUILD=sphinx-build2.7
- make dist
-
- Note: configure parameters are not important for the RPM building - except the `with-pkg-extra-version` if you want to give the RPM a specific name to
- mark your own unoffical build
-
-5. Create RPM directory structure and populate with sources
-
- mkdir rpmbuild
- mkdir rpmbuild/SOURCES
- mkdir rpmbuild/SPECS
- cp redhat/*.spec rpmbuild/SPECS/
- cp frr*.tar.gz rpmbuild/SOURCES/
-
-6. Edit rpm/SPECS/frr.spec with configuration as needed
- Look at the beginning of the file and adjust the following parameters to enable or disable features as required:
-
- ############### FRRouting (FRR) configure options #################
- # with-feature options
- %{!?with_pam: %global with_pam 0 }
- %{!?with_ospfclient: %global with_ospfclient 1 }
- %{!?with_ospfapi: %global with_ospfapi 1 }
- %{!?with_irdp: %global with_irdp 1 }
- %{!?with_rtadv: %global with_rtadv 1 }
- %{!?with_ldpd: %global with_ldpd 1 }
- %{!?with_nhrpd: %global with_nhrpd 1 }
- %{!?with_eigrp: %global with_eigrpd 1 }
- %{!?with_shared: %global with_shared 1 }
- %{!?with_multipath: %global with_multipath 256 }
- %{!?frr_user: %global frr_user frr }
- %{!?vty_group: %global vty_group frrvty }
- %{!?with_fpm: %global with_fpm 0 }
- %{!?with_watchfrr: %global with_watchfrr 1 }
- %{!?with_bgp_vnc: %global with_bgp_vnc 0 }
- %{!?with_pimd: %global with_pimd 1 }
- %{!?with_rpki: %global with_rpki 0 }
-
-7. Build the RPM
-
- rpmbuild --define "_topdir `pwd`/rpmbuild" -ba rpmbuild/SPECS/frr.spec
-
- If building with RPKI, then download and install the additional RPKI
- packages from
- https://ci1.netdef.org/browse/RPKI-RTRLIB/latestSuccessful/artifact
-
-DONE.
-
-If all works correctly, then you should end up with the RPMs under
-`rpmbuild/RPMS` and the Source RPM under `rpmbuild/SRPMS`
-
-
-Enabling daemons after installation of the package:
----------------------------------------------------
-
-### init.d based systems (ie CentOS 6):
-
-1. Edit /etc/frr/daemons and enable required routing daemons (Zebra is probably needed for most deployments, so make sure to enable it.)
-
-2. Enable the daemons as needed to run after boot (Zebra is mandatory)
-
- chkconfig frr on
-
-3. Check your firewall / IPtables to make sure the routing protocols are
-allowed.
-
-5. Start the FRR daemons (or reboot)
-
- service frr start
-
-Configuration is stored in `/etc/frr/*.conf` files and daemon selection is stored in `/etc/frr/daemons`.
-
-
-### systemd based systems (ie CentOS 7, Fedora 24)
-
-1. Edit /etc/frr/daemons and enable required routing daemons (Zebra is probably needed for most deployments, so make sure to enable it.)
-
-2. Enable the frr daemons to run after boot.
-
- systemctl enable frr
-
-2. Check your firewall / IPtables to make sure the routing protocols are
-allowed.
-
-3. Start the daemons (or reboot)
-
- systemctl start frr
