Open Stack

I understand Britt, thanks.

So I disabled DVR and tried  to test L3_HA, but it's not working properly,
it seems a keepalived issue. I see that it's running on 3 nodes:

[root at controller01 keepalived]# neutron l3-agent-list-hosting-router
harouter
+--------------------------------------+--------------+----------------+-------+
| id                                   | host         | admin_state_up |
alive |
+--------------------------------------+--------------+----------------+-------+
| 09cfad44-2bb2-4683-a803-ed70f3a46a6a | controller01 | True           |
:-)   |
| 58ff7c42-7e71-4750-9f05-61ad5fbc5776 | compute03    | True           |
:-)   |
| 8d778c6a-94df-40b7-a2d6-120668e699ca | compute02    | True           |
:-)   |
+--------------------------------------+--------------+----------------+-------+

However if I reboot one of the l3-agent nodes it stops working. I see this
in the logs:

*Dec 23 16:12:28 Compute02 Keepalived_vrrp[18928]: ip address associated
with VRID not present in received packet : 172.16.28.20*

Any hint?

Thanks
