Re: Layer 2 Transport

[Yan Filyurin <yanf787 () gmail com>]

It is tough to argue against VXLAN or anything over UDP, but another
workhorse of L2 services, especially for cheaper equipment and needing to
go over the top was L2TPv3.

Some interesting stuff was done by Wireguard and Softether, but I am not
sure it counts as service. MPLS-TP is still listed in MEF specs, but the
hopefully equipment supporting that is collecting dust on shelves
somewhere.

There could even be a network somewhere that is doing some variation of
SPB, hopefully converting to EVPN.
