One thing that comes to mind is that it seems that some routers only have limited space in their routing tables for prefixes longer than a /64. If you would configure a /127 on the link but push the /64 to the routing table then you might both avoid ND Cache exhaustion and avoid the limitations on longer-than-/64 prefixes. I personally prefer to set up my addressing plan that things like this are possible even if I don't do it today, but I also understand the choices you make. I don't think any of the choices is wrong. It mostly depends on expectations, used equipment and personal preference. And thanks for mentioning "Minimum assignment to a customer: /60". That is indeed a very important one! Cheers, Sander
