After receiving an e-mail from a newer [[China based switch OEM](https://starry-networks.com/)], I
had a chat with their founder and learned that the combination of switch silicon and software may be
a good match for IPng Networks. You may recall my previous endeavors in the Fiberstore lineup,

20x10G, 4x25G and 2x40G optics, and its larger sibling the S5860-48SC which comes with 48x10G and
8x100G cages. I use them in production at IPng Networks and their featureset versus price point is
pretty good. In that article, I made one critical note reviewing those FS switches, in that they'e

means that these switches would be fine participating in Area 0. If CAM space does turn into an
issue down the line, I can put them in stub areas and advertise only a default. As an aside, VPP

What folks don't always realize is that the industry is _moving on_ from MPLS to a set of more
flexible IP based solutions, notably tunneling using IPv4 or IPv6 UDP packets such as found in VxLAN
or GENEVE, two of my favorite protocols. This certainly does cost a little bit in VPP, as I wrote
about in my post on [[VLLs in VPP]({% post_url 2022-01-12-vpp-l2 %})], although you'd be surprised

how many VxLAN encapsulated packets/sec a simple AMD64 router can forward. With respect to these
switches, though, let's find out if tunneling this way incurs an overhead or performance penalty.
