<div>Unfortunately I've not had a chance yet to play with neutron router HA, so no hints from me. =( Can you give a little more details about "it stops working"? I.e. You see packets dropped while controller 1 is down? Do packets begin flowing before controller1
comes back online? Does controller1 come back online successfully? Do packets begin to flow after controller1 comes back online? Perhaps that will help.</div>

</div>
<div>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:</div>
<div><br>
</div>
<div>[root@controller01 keepalived]# neutron l3-agent-list-hosting-router harouter</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
<div>| id | host | admin_state_up | alive |</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
<div>| 09cfad44-2bb2-4683-a803-ed70f3a46a6a | controller01 | True | :-) |</div>
<div>| 58ff7c42-7e71-4750-9f05-61ad5fbc5776 | compute03 | True | :-) |</div>
<div>| 8d778c6a-94df-40b7-a2d6-120668e699ca | compute02 | True | :-) |</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
<div><br>
</div>
<div>However if I reboot one of the l3-agent nodes it stops working. I see this in the logs:</div>
<div><br>
</div>
<div>

<div>
<div dir="ltr">Hi all,
<div><br>
</div>
<div>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:</div>
<div><br>
</div>
<div>
<div>[root@controller01 ~]# neutron l3-agent-list-hosting-router router</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
<div>| id | host | admin_state_up | alive |</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
<div>| 09cfad44-2bb2-4683-a803-ed70f3a46a6a | controller01 | True | :-) |</div>
<div>| 0ca01d56-b6dd-483d-9c49-cc7209da2a5a | controller02 | True | :-) |</div>
<div>| 52379f0f-9046-4b73-9d87-bab7f96be5e7 | compute01 | True | :-) |</div>
<div>| 8d778c6a-94df-40b7-a2d6-120668e699ca | compute02 | True | :-) |</div>
<div>+--------------------------------------+--------------+----------------+-------+</div>
</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>Thanks</div>
</div>
</div>
</div>
