[talk] vxlan interfaces

[Pete Wright]

noticed this addition to FreeBSD in the 10.2-RELEASE notes yesterday:

"The vxlan(4) driver has been added, which creates a virtual Layer 2 
(Ethernet) network overlaid in a Layer 3 (IP/UDP) network. The vxlan(4) 
driver is analogous to vlan(4), but is designed to be better suited for 
large, multiple-tenant datacenter environments. [r284365]"

https://www.freebsd.org/cgi/man.cgi?query=vxlan&apropos=0&sektion=4&manpath=FreeBSD+10.2-RELEASE&arch=default&format=html

This looks pretty interesting to me and it looks like this is supported 
by Cisco (as well as other switch vendors probably too).  Has anyone on 
the list used this in production?

I'd love to hear some use-cases - I can think of it being useful in the 
virutalization world (amazon VPC for example).

cheers!
