Dear list,
I know that this question is not NetBSD specific per see, but I am aware that some of you out there have implemented and used vxlan-like technologies to extend networks at L2. Some have worked on it with rump [1].
$DAYJOB is currently investigating using these kind of technologies (mostly: vxlan or otv) to extent "seamlessly" L2 networks between two "zones", but as I have never used such protocols I am bit at a loss here, especially on the administrativia stuff.
If any of you used or use it and is willing to share (privately or not) his opinion on these, I will gladly take it, especially for things at a larger scale than what I could achieve on my small test bench. I am bit wary of L2 extension protocols when it regards scalability of the infrastructure, specifically for large networks (I guess that an alternative to STP needs to be used here?).
Thanks :)
