After discussing basic L2, L3 and Overlay functionality in my [[previous post]({{< ref "2022-12-05-oem-switch-1" >}})], I left somewhat of a cliffhanger alluding to all this fancy MPLS and
VPLS stuff. Honestly, I needed a bit more time to play around with the featureset and clarify a few things.
I'm now ready to assert that this stuff is really possible on this switch, and if this tickles your fancy, by
all means read on :)

### MPLS

Why even bother, if we have these fancy new IP based transports that I [[wrote about]({{< ref "2022-12-05-oem-switch-1" >}})] last week? I mentioned that the industry is _moving on_ from MPLS
to a set of more flexible IP based solutions like VxLAN and GENEVE, as they certainly offer lots of
benefits in deployment (notably as overlays on top of existing IP networks).

### Conclusions
It's just super cool to see a switch like this work as expected. I did not manage to overload it at

all, in my [[previous article]({{< ref "2022-12-05-oem-switch-1" >}})], I showed VxLAN, GENEVE and
NvGRE overlays at line rate. Here, I can see that MPLS with all of its Martini bells and whistles,
and as well the more advanced VPLS, are keeping up like a champ. I think at least for initial
configuration and throughput on all MPLS features I tested, both the small 24x10 + 2x100G switch,
