Permit me to rephrase... There is nothing that in my mind would justify the community
granting more than one 6rd prefix to an ISP, given the incredible waste inherent in the
first one. I would advocate that, instead, if you want to do TE with your 6rd, you should,
as an ISP, either disaggregate your 6rd prefix accordingly, or, you should move towards
a more native solution where you could get appropriate native allocations with much
less wastage.
