Hi Andy,

Let’s drop this.  No one intend to break anything.  Any talk in this direction is trash talk, hence let’s avoid it.

Thanks,

Andrew

Stewart has it right:

If that is not a requirement in your world, then I suggest
that you get a new ethertype and call it MPLS2

This is enough of a deviation from the millions of devices in the installed base that you can just get a new Ethertype and optimize to your heart's content. You're going to need new ASICs anyway, may as well go all the way. This also removes the need to do any sort of peer capability negotiation for backwards compatibility, and gives you the freedom to produce devices that ONLY support MPLS2 if you so desire, to have a less expensive and optimized data center solution. I would support standardization in this case.

Cheers,
Andy
