I was looking through draft-ietf-sidr-arch-00.txt and I noticed this:
5.2.2. Multi-homing
If a multi-homed subscriber wants multiple ASes to originate routes
for prefixes that it holds, then it must explicitly authorize
each of
them to do so by issuing a ROA for each AS in question.
Does this address the solution where multihomer M uses ISPs A and B,
and M's prefix is injected into BGP by both A and B and NOT by M?
I.e., "inconsistent origin AS", which is frowned upon.
If not, the text is unclear. If so, why is there no discussion of the
normal situation where the multihomed AS advertises its prefix itself?
Same thing for portable allocations without multihoming, although
there the situation where the ISP originates the prefix is more common.
BTW, it would be helpful if the availability of new drafts would be
announced on the list with the draft name in the subject.
