Package: networking-ofagent
What’s thisThis is OpenStack/Networking (Neutron) “ofagent” ML2 driver and its agent.InstallationFor how to install/set up ML2 mechanism driver for OpenFlow Agent, please refer tohttps://github.com/osrg/ryu/wiki/OpenStackNotes for updating from IcehouceOVS.bridge_mappings is deprecated for ofagent.  It was removed in Kilo.
Please use AGENT.physical_interface_mappings instead.
To mimic an existing setup with bridge_mapping, you can create
a veth pair, link one side of it to the bridge, and then specify
the other side in physical_interface_mappings.
For example, if you have the following:[OVS]
bridge_mappings=public:br-exYou can do:# ip link add int-public type veth peer name phy-public
# ip link set int-public up
# ip link set phy-public up
# ovs-vsctl add-port br-ex phy-publicand then replace the bridge_mappings with:[AGENT]
physical_interface_mappings=public:int-publicAfter Icehouce, most of the functionality have been folded into
a single bridge, the integration bridge.  (aka. br-int)
The integration bridge is the only bridge which would have an
OpenFlow connection to the embedded controller in ofagent now.ofagent no longer uses a separate bridge for tunneling.
Please remove br-tun if you have one:# ovs-vsctl del-br br-tunofagent no longer acts as an OpenFlow controller for physical bridges.
Please remove set-controller configuration from your physical bridges:# ovs-vsctl del-controller ${PHYSICAL_BRIDGE}The support of ancillary bridges has been removed after Icehouce.
While you can still use these bridges to provide connectivity,
neutron-ofagent-agent no longer reports port state changes (up/down)
for these bridges.  If it is a problem for you, please consider
tweaking your configuration to avoid using ancillary bridges.
We recommend to use a provider network instead as the following:Make l3-agent external_network_bridge configuration empty:[DEFAULT]
external_network_bridge=(Re-)create a network (and subnet) for public connectivity with
a flat provider network:neutron net-create $PUBLIC_NETWORK -- \
  --router:external=True \
  --provider:network_type:flat \
  --provider:physical_network=$PUBLIC_PHYSICAL_NETWORKAssociate your neutron router to the above network:neutron router-gateway-clear $ROUTER_ID
neutron router-gateway-set $ROUTER_ID $PUBLIC_NETWORKAdd the corresponding entry to bridge_mappings:[OVS]
bridge_mappings=$PUBLIC_PHYSICAL_NETWORK:$PUBLIC_BRIDGEThe port naming scheme for ofagent has been changed after Icehouce.
If you are using security groups, you should switch firewall_driver
accordingly.From:[securitygroup]
firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverTo:[securitygroup]
firewall_driver=neutron.agent.linux.iptables_firewall.IptablesFirewallDriverExternal ResourcesOFAgent documentation on ReadTheDocshttp://networking-ofagent.readthedocs.org/en/latest/Neutron/OFAgent on OpenStack wikihttps://wiki.openstack.org/wiki/Neutron/OFAgentRyuOFAgent uses Ryu ofproto library to communicate with the local switch.For general Ryu stuff, please refer tohttp://osrg.github.io/ryu/Ryu is available at github
