[c-nsp] IPv6 subnets for point-to-point links

[Marcel Lammerse]

Dear all,

according to the documentation I'm reading, it is not recommended to  
assign /127 subnets on IPv6 point-to-point links since it breaks some  
IPv6 mechanisms. An example is duplicate-address-detection (dad),  
which uses a subnet-router anycast address, that would conflict with  
one of the two available address on the link. However, the same  
documentation mentions that it was popular practice on the 6bone.

This confuses me.

Is it or is it not safe practice to use /127  instead of the  
recommended /64 and waste a lot of address? What are people typically  
using?

Thanks,
Marcel
