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?
