L2 agent extensions¶

Open vSwitch agent API¶

• neutron.plugins.ml2.drivers.openvswitch.agent.ovs_agent_extension_api

Open vSwitch agent API object includes two methods that return wrapped and hardened bridge objects with cookie values allocated for calling extensions:

#. request_int_br
#. request_tun_br

Bridge objects returned by those methods already have new default cookie values allocated for extension flows. All flow management methods (add_flow, mod_flow, …) enforce those allocated cookies.
