Hi Jake,
<div><br>
</div>
<div>That’s something that I wanted to check if it was needed/recommended.</div>
<div><br>
</div>
<div>Can certainly put it in if it will help achieve better performance and redundancy<br>
<br>

<div>In the diagram there isn’t a peer link between 13 & 14 - is that a mistake in the diagram or the actual design?</div>

<div>If you intend to build 2x20G bonds to two standalone nexus switches, that’ll work fine.</div>
<div><br>
</div>
<div>If you are trying to achieve a 40G bowtie between the two pairs I’m fairly certain that won’t work (unless Cisco has some special black magic to transport signalling/MAC synchronisation over the bond itself).</div>
