So now, we changed topic to multihoming to two ISPs
with hole-punching, right? This is what we do today
with two issues:
a) increase the size of the global routing table since
it can not be aggregated, and
b) The longer prefixes (the hole) could be blocked by
certain providers resulting in no access to that part
of the Internet.
I think this mechanism works today in IPv4 and there
is no reason why can not be used for Ipv6. However, it
does not hurt to have other mechanism which allow
better aggregation available if there are concerns
about the scaling and routability issues listed above.
Speaking as a person who had worked for ISPs and dealt
with operations for many many years, I submit there
are entities who would like to have the arrangement as
described in the ID.
Thanks!
