FRR

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

Initialization

Install the FRR YANG modules in the Sysrepo datastore:

# sysrepoctl --install --yang=/usr/local/share/yang/frr-interface.yang
# sysrepoctl --install --yang=/usr/local/share/yang/frr-isisd.yang

Start sysrepod and netopeer2-server

# sysrepod -l 1 -d &
# 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 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"
      }
    ]
  }
}
