What is the point of an ASN if all you are multi-homing is a single subnet?
Tony,
I'm missing the correlation between the amount of address space announced and multihoming. (Beyond the prefix being too long and potentially filtered). Care to elaborate?

The only reason for an ASN is the need to globally announce routing policy due to multihoming. Unless policy changes, this community tends to insist that the prefix length announced via that ASN corresponds to a site, not a single subnet. For IPv6 that means a /48 makes sense as an initial allocation with a new ASN, and a /64 does not. Tony
