L2 agent extensions

L2 agent extensions are part of a generalized L2/L3 extension framework. See 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.
