Think of the Fabricpath core kinda like Layer3 core just that we're routing Layer 2 frames as the payload. We still run into the same limitation if we try to connect a host into two different switches, we cannot form a single port-channel/LAG between them.

<p>A bit late, I know, but I would have thought that IEEE 802.1aq

<b>Subject:</b> [AusNOG] How to setup something like
LACP across two switches</span></p>
<p class="MsoNormal"> </p>
<div>
<p class="MsoNormal">Hello Fellow Ausnoggers,</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I'm hoping that I can quickly
pick the brain of someone more knowledgeable in
data centre networking than myself.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">We have a customer in one of
our racks in Equinix who has a single network
switch, and some servers connected to it. We
currently have two connections from our switch to
the customer's switch, with LACP for redundancy
(and as a side effect, we get a slight bandwidth
boost for 2 x 1Gbps connections, which is a slight
bonus).</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">We would like to improve this
by putting in two network switches on our end, to
protect again a single switch failure on our side,
but the customer will still have one single
network switch.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I'm pretty sure we can't do
LACP with this style of setup - so what would
people recommend to achieve redundancy here? Main
thing is that the connection needs to
auto-failover if a network switch fails, or if one
of the uplinks fails.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">I have created the attached
diagram which illustrates what we are trying to
do.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Can anyone please help? I'll
owe a beer at the Next AusNOG meetup!</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Thanks</p>
