Just to be clear, this isn't part of my DISCUSS position so it's not
critical to resolve it.  I just think the document would be simpler with
unnecessary definitions removed.

Can you show me where any of the ones I listed, except for "SA", are
included in test setup configuration?

A couple of terms like like AA might not be used explicitly.

I don't understand why you would include a definition of "AA" if you don't
actually use it anywhere.

Specifically:

"All-Active Redundancy Mode" appears nowhere in the document other than its
own definition.  It may be an interesting or important concept, but it
appears to be unrelated to the rest of this document, and it would thus be
simpler to remove it.

Neither "AA" nor "All-Active" are present anywhere in the document other
than the Terminology section.  You could remove them and the document reads
the same way.

"Ethernet Segment" only appears in the Terminology section, as part of its
own definition or of other definitions.  "ES" appears nowhere.  They could
also be removed.

"RT" appears nowhere.  "Traffic generator" does, but not "RT".  Maybe you
should define "Traffic generator" instead of "RT"?

"Sub interface" doesn't appear anywhere.  Why does it need to be defined?

"Single-Active Redundancy Mode" defines itself, and then "SA" is introduced
as a short form for it and is actually used in several places.  I would
suggest replacing those two with this one:

SA: Single-Active Redundancy Mode. When a single PE (among all the PEs
   attached to an Ethernet segment) is the only PE allowed to forward
   traffic to/from a given Ethernet segment for a given VLAN, then that
   Ethernet segment is defined to be operating in Single-Active
   Redundancy Mode.
