Hi Stephen,

Thanks very much for the tip. Here is the output on my box,

/sbin/modinfo vxlan

# ip -V
ip utility, iproute2-ss111117

So I think I'm all set to give it a try?

Thanks.

VXLAN driver is part of the kernel config. 
If using a vendor supplied kernel, most likely it is available as a module.
Try:
   /sbin/modinfo vxlan
If you see 'ERROR: Module vxlan not found' then vxlan was not configured.
You will also need to have current iproute2 utilities.
   $ ip -V
ip utility, iproute2-ss121211
