Another idea would be to give each non-/48 customer the first /56 out of each /48. If you started out with a /30 or /31 RIR block , by the time you run out of /48s, you can either start using up the subsequent /56s out of the first /48, as it's likely that the first /56 customer out of the /48 would have needed the /48 by that time.
As stated, that approach has really negative implications for the number of routes you carry in your IGP.
Alternatively you might have become more comfortable with giving each customer a /48, and wouldn't require any of them to renumber - they'd just have to shorten their prefix length. Regards, Mark.
