The OpenDaylight website +contains more information on the capabilities OpenDaylight provides: + + http://www.opendaylight.org + +Theory of operation +=================== +The OpenStack Neutron integration with OpenDaylight consists of the ML2 +MechanismDriver which acts as a REST proxy and passess all Neutron API +calls into OpenDaylight. OpenDaylight contains a NB REST service (called +the NeutronAPIService) which caches data from these proxied API calls and +makes it available to other services inside of OpenDaylight. One current +user of the SB side of the NeutronAPIService is the OVSDB code in +OpenDaylight. OVSDB uses the neutron information to isolate tenant networks +using GRE or VXLAN tunnels. + +How to use the OpenDaylight ML2 MechanismDriver +=============================================== +To use the ML2 MechanismDriver, you need to ensure you have it configured +as one of the "mechanism_drivers" in ML2: + + mechanism_drivers=opendaylight + +The next step is to setup the "[ml2_odl]" section in either the ml2_conf.ini +file or in a separate ml2_conf_odl.ini file. An example is shown below: + + [ml2_odl] + password = admin + username = admin + url = http://192.168.100.1:8080/controller/nb/v2/neutron + +When starting OpenDaylight, ensure you have the SimpleForwarding application +disabled or remove the .jar file from the plugins directory. Also ensure you +start OpenDaylight before you start OpenStack Neutron. + +There is devstack support for this which will automatically pull down OpenDaylight +and start it as part of devstack as well. The patch for this will likely merge +around the same time as this patch merges. -- cgit 1.2.3-korg
