Well, that is actually one of the questions. B1 and B2 are on

You can manage the replication topology with ipa-replica-manage
connect and disconnect. So if you want B1 and B2 connected you
can do that. <br>

The main question is that B1 and B2 are not replicated to each
other <br>
automatically? What about the case if <br>
<br>
A1 -- replication -- A2 --- replication --- B1 -- replication
-- B2 <br>
<br>
If B1 gets destroyed, how B2 and A2 (and A1) gets
synchronized? <br>
Especially automatically...? <br>
Is there such a failover configuration? <br>
</blockquote>
<br>
No, the masters only replicate to the ones you tell them to, so
if B1 went away forever then B2 would never get any other
updates unless you explicitly made a connection to A1 or A2. <br>

<br>
Can the replication agreement be circular?<br>
<br>
<b>A2</b>-A1-B1-B2-<b>A</b><b>2</b>?<br>

<br>
Yes.<br>
