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@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* *Dec 23 16:12:28 Compute02 Keepalived_vrrp[18928]: one or more VIP associated with VRID mismatch actual MASTER advert* *Dec 23 16:12:28 Compute02 Keepalived_vrrp[18928]: bogus VRRP packet received on ha-a509de81-1c !!!* *Dec 23 16:12:28 Compute02 Keepalived_vrrp[18928]: VRRP_Instance(VR_1) ignoring received advertisment...* *Dec 23 16:13:10 Compute03 Keepalived_vrrp[12501]: VRRP_Instance(VR_1) ignoring received advertisment...* *Dec 23 16:13:12 Compute03 Keepalived_vrrp[12501]: ip address associated with VRID not present in received packet : 172.16.28.20* *Dec 23 16:13:12 Compute03 Keepalived_vrrp[12501]: one or more VIP associated with VRID mismatch actual MASTER advert* *Dec 23 16:13:12 Compute03 Keepalived_vrrp[12501]: bogus VRRP packet received on ha-d5718741-ef !!!* *Dec 23 16:13:12 Compute03 Keepalived_vrrp[12501]: VRRP_Instance(VR_1) ignoring received advertisment...* Any hint?
