Given that APNIC are now assigning 4-byte AS numbers by default, I wondered what the state of play was among members of this list. You can still get 2-byte AS numbers:
"Two-byte AS numbers will only be assigned if the applicant can demonstrate that a four-byte only AS number is unsuitable."
but come January 2010 numbers will be assigned without distinction.
Is anyone out there ready for this?
I'm seeing some routing oddities with one client that has been assigned a 2-byte ASN, but it seems all the issues are upstream.
Do you mean 4 byte?
It seems that not everyone is ready. I think we need to send some folks a good supply of beer to make sure they upgrade their software.
Well, it should be backwards compatible for the most part. An AS with a 4-byte will need full support on all their kit, but they should be able to interconnect with peers without any problems. The non-4-byte AS sees it as AS23456. -- Nathan Ward
