Hi Geoff,
Do you have any plan for another trial longer and notified
so that everyone with various implementations of OLD SPEAKER
can observe this and check if they normally handle a 4-byte
ASN?
Regards,
Akinori

| George Michaelson, Randy Bush and myself have successfully tested the
| implementation of 4Byte AS BGP on a public Internet transit. The
| above BGP RIB snapshot was taken at a 4Byte BGP speaker in North
| America, showing a transit path across AS 1221, AS 4637, AS 1239 and
| AS 3130 , with correct reconstruction of the originating AS at the
| other (4Byte AS) end.
|
| The code base used was OpenBGPD, with 4 byte patches that I've added
| to the code in the past couple of weeks.
