<div class="moz-cite-prefix">RE: bridging, that's just sort of how
they work, so they can control the mac domain locally and forward
out. Including dot1q trunking, and it starts making more sense.
Add in things like Openstack, VMware+NSX, anything that does layer
2 virtualization over vxlan bridging, and bridging is just how
it's mostly done. The bridge is the local host "vlan" so to
speak, extending the switch ports to a local "lan" of sorts,
namely your bridge and virtual interfaces in it.<br>
<br>
This still creates a software buffer to deal and contend with, as
well as how they interact with the hardware phy (again, offload
and such), so make sure you're tuning around the bridges as well,
txqueues, sysctls, etc for br* too.<br>

The backend network these servers are connected to are a Cisco

<br>
All my research says to use a network bond running LCAP for
best<br>
compatability/performance with this hardware. it all seems to
be running,<br>
but it is kind of weird that Proxmox would want me to create
the bridge for<br>
the VMs to run on kind of makes sense just feels weird to run
a bond<br>
inside bridge.<br>
<br>
If anyone who has worked with proxmox has a better suggestion
please let me<br>
know.<br>
<br>
Thanks for your time.<br>
