[routing-wg]Four byte ASN notation

For what it is worth, I agree with Gert.

I can see a strong argument for storing the ASNs as an unsigned 32 bit 
number internally, but the user-interface and education needs to start 
happening now before the larger ASNs become routine.  We only have 
just over a year until 32 bit ASNs are the default for RIR 
assignments.  "asdot" is becoming the default, and one of the reasons 
for having the discussion in October was that if there was a strong 
desire for another representation, operators would have to express 
that before asdot became a fait accomplis.

I was, and am, aware of George Michaelson's draft, which is why I used 
the terminology from it when I summed up what I felt the feeling in 
the room was.

Cheers,
Rob
