If you decide to use /64s for the interconnect, make sure to only assign a
/126 (or /127, whichever you want) to the interfaces.

Assigning 2001:db8:1:1::1/64 to an interface is a good way to be vulnerable
to neighbour cache exhaustion denial of service attacks.

My 2 cents is that you should allocate a /64 for readability, but assign
only /127's to each end.
