This doesn't seem to be something that should be sent to the OpenStack-dev list. For HA neutron you probably want to look at L3 HA via VRRP. It uses Keepalived to manage IPs between multiple L3 Gateways. (Active Passive) - https://wiki.openstack.org/wiki/Neutron/L3_High_Availability_VRRP I don't know if any documentation for configuring L3_HA has gone up, but I did a brief overview on that at: - http://nakato.io/2014/10/30/Neutron-L3-VRRP/ DVR places Floating IP's on the hypervisor that hosts the VM that it is allocated to, which isn't really HA, but really is probably HA enough. It does more this this, but that's best read from the following two docs. - https://wiki.openstack.org/wiki/Neutron/DVR - https://wiki.openstack.org/wiki/Neutron/DVR_L2_Agent Keep in mind DVR and L3_HA are currently incompatible with each other.
