I have same problem. I'm using pacemaker - corosync to HA my network node. But the resource agent use for L3-agent (download from https://github.com/madkiss/openstack-resource-agents/blob/master/ocf/neutron-agent-l3) in not working with my deployment (Neutron server is on Controller node and other agent in Network Node).
The bug: https://bugs.launchpad.net/openstack-manuals/+bug/1328922
Do you have any ideas?

This was the old pre-Juno way of doing things:
I never actually implemented this, but I can tell you from anecdotal tales of woe that it is far from perfect HA. You will experience downtime with an agent failure. How much depends on the number of routers you have since they all have to be created on the new agent node upon failover. You really should consider an upgrade rather than go through this if you can manage it.
