No, (global) AS number is definitely not required, and if you really want, you could do without even a private ASn.
A rather common scenario is to use private ASN to two providers, and leak more specifics from beyond your preferred ISP to the world -- and connect to the ISP as a secondary which owns the aggregate.
Might be so, but even I am opposed to such ugliness. I have yet to see it, probably because most people doing so are ashamed of the practice... Furthermore, it might be possible to deprecate the behaviour of multihoming without public AS in v6, simply because few people will accept routes for smaller prefixes than /32.. -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE We're sysadmins.
