</div>For DRBD, that's a fine and recommended appproach.<br>

For Corosync, there's an underlying misconception here. You essentially<br>
always want to run cluster communications over more than one link, so<br>
you would run your Corosync traffic over _both_ your back-to-back cable<br>
and your switched network. Corosync calls this redundant rings.<br>
