Guidelines for Numbering IPv6 Point-to-Point Links and Easing the Addressing Plans

http://www.consulintel.euro6ix.org/ietf/draft-palet-v6ops-point2point-00.html

There are different alternatives for numbering IPv6 point-to-point links, and from an operational perspective, they may have different advantages or disadvantages that need to be taken in consideration under the scope of each specific network architecture design.

However, as a general rule, this document suggest the approach of using /64 in order to ensure not only compliance with standards, and consequently facilitate interoperability, but also in order to ensure avoiding possible future issues and simplifying the addressing plans.

The use of /64 also facilitates an easier way for routing the shorter aggregated prefix into the point-to-point link. Consequently it simplifies the "view" of a more unified addressing plan, providing an easier path for following up any issue when operating IPv6 networks.
