<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I think Robert's comment is correct. The router is currently hosted on agent "789a77fd-52ff-44be-afea-27d26a8cd3d3". This was assigned at the router's creation by the router scheduler (currently only a chance scheduler exists, so it's random).<br>
<br>
You cannot host the same logical router on more than one l3-agent at once, which is likely why you're getting the error when you attempt to add the router to an L3-agent.<br>
<br>
If you want to specify which L3-agent is hosting a specific router, you would do something like the following:<br>
<br>
quantum l3-agent-list-hosting-router router01 <copy the agent ID, in this case: 789a77fd-52ff-44be-afea-27d26a8cd3d3><br>
quantum agent-list | grep L3<br>
<copy agent ID you want to move the router onto> quantum l3-agent-router-remove <agent ID the router is currently hosted on> <router-id> quantum l3-agent-list-hosting-router router01 <verify the router is no longer hosted on any L3-agent> quantum l3-agent-router-add <agent ID where you would like the router to be hosted> <router-id> quantum l3-agent-list-hosting-router router01 <verify the router is now hosted on the new l3-agent><br>
<br>
I personally would get router01's UUID and use that in place of the name router01, but it *should* work either way.<br>
<br>
But, to your original question, you shouldn't have to add the router to an agent as that should happen at router creation time by the scheduler (as Robert said).<br>

<br>
Hi,<br>
<br>
<br>
the output is:<br>
<br>
<br>
<br>
<br>
quantum l3-agent-list-hosting-router router01<br>
<br>
+--------------------------------------+---------------+----------------+-------+<br>
| id | host | admin_state_up | alive |<br>
+--------------------------------------+---------------+----------------+-------+<br>
| 789a77fd-52ff-44be-afea-27d26a8cd3d3 | seoul | True | :-) |<br>
+--------------------------------------+---------------+----------------+-------+<br>
<br>
<br>
However, shouldn't the l3-agent running on each compute host be attached to the router, or am I completely misunderstanding somethning?<br>
<br>
<br>
Thanks,<br>

<br>
Not sure what you are trying to accomplish here.<br>
Scheduling, by default, happens automatically unless you have multiple routers and want to set it up to run a router on a specific l3-agent.<br>
<br>
Usually this should be enough:<br>
<br>
quantum router-create router1<br>
quantum router-interface-add router1 ${subnetname)<br>
<br>
What is the output of the following?:<br>
quantum l3-agent-list-hosting-router $(routername}<br>
<br>
Cheers,<br>
