<div><p>During normal operations, base clustering communication traffic
will be minimal. It is, however, highly recommended that you have redundant
communication paths configured for each node in a cluster. </p>
<p>By configuring two lines, you can dedicate one line for clustering traffic
and the other line can handle the normal traffic and also be the backup line
if the dedicated line for clustering goes down.</p>
