Well, if you want to be really environmentally conscious, do away with that /126 too and just use link-locals, with a single global address per router for management and the generation of ICMPs.
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?
