Sysrepo

$ git clone https://github.com/sysrepo/sysrepo.git
$ cd sysrepo/
$ mkdir build; cd build
$ cmake -DCMAKE_BUILD_TYPE=Release -DGEN_LANGUAGE_BINDINGS=OFF .. && make
# make install

libnetconf2

$ git clone https://github.com/CESNET/libnetconf2.git
$ cd libnetconf2/
$ mkdir build; cd build
$ cmake .. && make
# make install

netopeer2

$ git clone https://github.com/CESNET/Netopeer2.git
$ cd Netopeer2
$ cd server
$ mkdir build; cd build
$ cmake .. && make
# make install

Note: If make install fails as it can't find libsysrepo.so.0.7, then run ldconfig and try again as it might not have updated the lib search path

FRR

Build and install FRR using the --enable-sysrepo configure-time option.

Initialization

Install the FRR YANG modules in the Sysrepo datastore:

# sysrepoctl --install /usr/local/share/yang/[email protected] 
# sysrepoctl --install /usr/local/share/yang/frr-vrf.yang 
# sysrepoctl --install /usr/local/share/yang/frr-interface.yang 
# sysrepoctl --install /usr/local/share/yang/frr-route-types.yang 
# sysrepoctl --install /usr/local/share/yang/frr-filter.yang 
# sysrepoctl --install /usr/local/share/yang/frr-route-map.yang 
# sysrepoctl --install /usr/local/share/yang/frr-isisd.yang 
# sysrepoctl --install /usr/local/share/yang/frr-ripd.yang
# sysrepoctl --install /usr/local/share/yang/frr-ripngd.yang
# sysrepoctl -c frr-vrf --owner frr --group frr
# sysrepoctl -c frr-interface --owner frr --group frr
# sysrepoctl -c frr-route-types --owner frr --group frr
# sysrepoctl -c frr-filter --owner frr --group frr
# sysrepoctl -c frr-route-map --owner frr --group frr
# sysrepoctl -c frr-isisd --owner frr --group frr
# sysrepoctl -c frr-ripd --owner frr --group frr
# sysrepoctl -c frr-ripngd --owner frr --group frr

Start netopeer2-server:

# netopeer2-server -d &

Start the FRR daemons with the sysrepo module:

# isisd -M sysrepo --log=stdout

Managing the configuration

The following NETCONF scripts can be used to show and edit the FRR configuration: https://github.com/rzalamena/ietf-hackathon-brazil-201907/tree/master/netconf-scripts

Example:

# ./netconf-edit.py 127.0.0.1
# ./netconf-get-config.py 127.0.0.1
<?xml version="1.0" encoding="UTF-8"?><data xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0"><isis xmlns="http://frrouting.org/yang/isisd"><instance><area-tag>testnet</area-tag><is-type>level-1</is-type></instance></isis></data>

NOTE: the ncclient library needs to be installed first: apt install -y python3-ncclient

The sysrepocfg tool can also be used to show/edit the FRR configuration. Example:

# sysrepocfg --format=json --import=frr-isisd.json --datastore=running frr-isisd
# sysrepocfg --format=json --export --datastore=running frr-isisd
{
  "frr-isisd:isis": {
    "instance": [
      {
        "area-tag": "testnet",
        "is-type": "level-1"
      }
    ]
  }
}
