You configure 2001:db8:abcd:1234::1/128 on A, and then configure 2001:db8:abcd:1234::2/128 on B. On A you route 2001:db8:abcd:1234::2/128 to the PtP interface, on B you route 2001:db8:abcd:1234::1/128 to the PtP interface. True Point-To-Point, with room to grow. Note that using a /127 might seem logical, it does not work due to the subnet-anycast address. Indeed, you 'lose' the rest of the /64, but when the time comes that you convert it to a multi-point link one can just add extra /128s in there. Greets, Jeroen
