Well, I guess a couple sentences could be added that the choice of
using aggregated nicknames, and the resulting possible duplication of
nicknames between areas, increases the possibility of a TRILL Data
packet being delivered to the wrong egress RBridge if areas are
suddenly merged. However, is many cases the data would be discarded at
that egress because it would not match a known end station data label
/ MAC address.

OK,

Apparently both of those are correct but I agree the draft should use
one of them consistently. I'll replace the two instances of nonzero
with the hyphenated form.

Thanks,
Donald
