Partial. Can be mounted from ODL but the OpenFlow part is not ready. - https://github.com/vlvassilev/yuma123/tree/master/example-modules/ietf-network-bridge

Incomplete.

Alternative southbound interface to flow enabled network bridges

This is a new project originally defined in the following post on hackathon@ietf.org https://mailarchive.ietf.org/arch/msg/hackathon/vb27RmJivbwy8UURV_KXh2IzZd0

The project consists of 3 tasks:

  1. Design and publish draft with YANG model of a flow enabled network bridge.
  2. Device (server) side model implementation - loadable module for some of the available opensource NETCONF servers implementing the model for a OpenFlow device as a proxy controller with a single node.
  3. Controller (client) side plug-in implementation - ncflowplugin for ODL interacting with NETCONF mounted nodes implementing the YANG model

that ideally can coexist with openflowplugin.

Progress:

Design and publish draft with YANG model of a flow enabled network bridge.

Done. https://datatracker.ietf.org/doc/draft-vassilev-netmod-network-bridge/

Device (server) side model implementation

Partial. Can be mounted from ODL but the OpenFlow part is not ready. - https://github.com/vlvassilev/yuma123/tree/master/example-modules/ietf-network-bridge

Controller (client) side plug-in implementation - ncflowplugin for ODL

Incomplete.

Walkthrough (tested on Debian)

Build and start netconfd server instance with the ietf-network-bridge* modules loaded listening on port 830: 

 cd
 sudo apt-get install git autoconf gcc libtool libxml2-dev libssh2-1-dev make libncurses5-dev zlib1g-dev libreadline-dev
 git clone git://git.code.sf.net/p/yuma123/git yuma123-git
 cd yuma123-git
 git checkout 328a64829243684da65891851bf22acb88ca16a5
 autoreconf -i -f
 ./configure CFLAGS='-g -O0' CXXFLAGS='-g -O0' --prefix=/usr
 make
 sudo make install
 #Enable the netconf subsystem and restart sshd
 echo "Port 830" | sudo tee -a /etc/ssh/sshd_config
 echo "Subsystem netconf "/usr/sbin/netconf-subsystem" | sudo tee -a /etc/ssh/sshd_config
 sudo /etc/init.d/ssh restart
 /usr/sbin/netconfd --module=/usr/share/yuma/modules/ietf/ietf-interfaces@2014-05-08.yang \
                    --module=/usr/share/yuma/modules/ietf/iana-if-type@2014-05-08.yang \
                    --module=/usr/share/yuma/modules/ietf-draft/ietf-network-bridge.yang \
                    --module=/usr/share/yuma/modules/ietf-draft/ietf-network-bridge-flows.yang \
                    --module=/usr/share/yuma/modules/ietf-draft/ietf-network-bridge-scheduler.yang \
                    --module=/usr/share/yuma/modules/examples/example-bridge.yang \
                    --startup=example-modules/ietf-network-bridge/example-bridge-cfg.xml --log-level=debug4 --superuser=${USER}

Validate everything is OK with NETCONF client: 

vladimir@lmf:~$ yangcli --server=localhost --ncport=830 --user=${USER}
