Currently HA and DVR are mutually exclusive features.

Subject: [Openstack-operators] Neutron DVR HA

Hi all,

I've been trying Neutron DVR with 2 controllers +  2 computes. When I create a router I can see that is running on all the servers:

[root at controller01 ~]# neutron l3-agent-list-hosting-router router
+--------------------------------------+--------------+----------------+-------+
| id                                   | host         | admin_state_up | alive |
+--------------------------------------+--------------+----------------+-------+
| 09cfad44-2bb2-4683-a803-ed70f3a46a6a | controller01 | True           | :-)   |
| 0ca01d56-b6dd-483d-9c49-cc7209da2a5a | controller02 | True           | :-)   |
| 52379f0f-9046-4b73-9d87-bab7f96be5e7 | compute01    | True           | :-)   |
| 8d778c6a-94df-40b7-a2d6-120668e699ca | compute02    | True           | :-)   |
+--------------------------------------+--------------+----------------+-------+

However if controller01 server dies I cannot ping ip external gateway anymore. Is this the expected behavior? Shouldn't it failback to the another controller node?

Thanks
