Well, if you want to be really environmentally conscious, do away
with that /126 too and just use link-locals, with a single global

and you ping the customer links how? (or did I miss the point of the
link-locals?)




You don't. I don't think the point of link-locals has much to do with
pinging customers... But since IPv6 routing protocols work over link-
locals you don't need global addresses.



If you want to ping your customers you should probably use a /126 so
they can only use the specific address you give them. You need that
anyway if you want to route a /48 or what have you to them.



BTW, there is discussion about rethinking /48s for customers in IPv6.
Thoughts?
