This addresses the issue of having one or more multi-homed host. Because you may only specify one local IP for a quantum agent, and other hosts could be routed across different subnets (even for small installations, for various reasons), it's important to also specify the used local_ip when setting up the GRE tunnels. As long as the address is routable on both ends, this will work. If the local_ip is not specified, then traffic will mysteriously be dropped on one end where the IP does not match the expected IP in the GRE tunnel.

The Open vSwitch (OVS) Neutron plugin is a simple plugin to manage OVS features using a local agent running on each hypervisor. For details on how to configure and use the plugin, see: http://openvswitch.org/openstack/documentation/
