Ethernet tunneling options under FreeBSD

[James Lott]

Hello list,

I am in the process of planning a build out of a L2 VPN, in which I'd 
like to have my primary "switch" and DHCP server be a FreeBSD system. I 
would like to join each new host to the VPN by establishing an IP tunnel 
with the primary "switch" which transports ethernet frames over the tunnel.

So far, the only protocol I have found supported by FreeBSD which seems 
capable of this is EtherIP. As far as I can tell, it doesn't look like 
there is any support for L2TPv3, and none of the PPP implementations 
available appear to support BCP.

I'm not completely opposed to using EtherIP, but if there is something 
more modern which will meet my needs, I would probably try that first. 
So my question becomes:

* Does anyone know of a method supported under FreeBSD (other than 
EtherIP) for tunneling ethernet over IP that they may be able to suggest 
I check out?

Thanks for any suggestions!
