<div>Jacob,</div>

</div>
<div>The two options I'm aware of are:</div>
<div><br>
</div>
<div>1. Active/Active using Quantum L2 only with Provider Networking Extensions. In this scenario, you leverage the physical data center network to provide L3 redundancy through mechanisms such as VRRP.</div>
<div>2. Active/Passive using Pacemaker.</div>

<div>At this time, not with the L3 Agent. I suggest following this bug:</div>

<div dir="ltr">Hi all,
<div><br>
</div>
<div>Has anyone successfully deployed a truly HA setup of Neutron (Quantum)? I've been reading about the agent scheduling functionalities etc., but they do not seem to provide true HA in a failure scenario. Particularly, this article lays it out nicely: <a href="http://www.mirantis.com/blog/a-new-agent-management-approach-in-quantum-for-openstack-grizzly/" target="_blank">http://www.mirantis.com/blog/a-new-agent-management-approach-in-quantum-for-openstack-grizzly/</a>.</div>
<div><br>
</div>
<div>I'm using OVS, and have a dedicated network node with my OVS, dhcp, and L3 agents running on it. What I want to do, is deploy those services to my "secondary" (or second active) networking node. In the case of a failure, this node should pick up any networking
tasks that the other node was responsible for.</div>
