Hi
In reference to the discussion about /31 for router links, I d'like to know what is your experience with IPv6 in this regard.
I use a /126 if possible but have also configured one /64 just for the link between two routers. This works great but when I think that I'm wasting 2^64 - 2 addresses here it feels plain wrong.
So what do you think? Good? Bad? Ugly? /127 ? ;)
Use the /64... It's OK... IPv6 was designed with that in mind. 64 bits is enough networks that if each network was an almond M&M, you would be able to fill all of the great lakes with M&Ms before you ran out of /64s. Owen
