Hi John,

I've posted -09 which should resolve your DISCUSS and COMMENTs.

Thanks for hopping threads, I shoulda caught that last one. Your proposed change looks fine, I’ll remove my DISCUSS in anticipation of you issuing a new version. (One nit on your new text, “in order maximize” should be “in order to maximize”.)

I guess when you changed your COMMENT to a DISCUSS it creates a new thread so I should reply here as I did to this when it was a COMMENT:

How about something more like:
EVPN Network OAM mechanisms MUST provide in-band monitoring capabilities. OAM messages SHOULD be encoded so that they exhibit similar entropy characteristics to data traffic in order maximize the fate sharing between OAM and data.
