Do you remember the old BSD paradigm? ... "less is more" 

I think it applies here. We are now in a time where a *smaller* routing
table entry list count is preferable to a 'full' table, because the
fullest table is likely to also include problematic BGP routing
information.

It is important to recognise that RPKI ROA creation is an *OPTIONAL*
protection mechanism. If you create ROAs, you indeed can harm your
network, but at the same time, if you create the ROAs correctly, you
will gain massive benefits.

RPKI ROA creation is a big hammer. Everyone needs to think carefully
about each ROA they create and if it will positively or negatively
impact their network. NTT spend *months* creating ROAs for all the
prefixes, researching for each BGP announcement if the ROA would be good
or bad. We now got virtually all our space covered by ROAs, it'snice.

Yes. "We made an impossible bird, and it was able to fly". :-)

The global deployment of RPKI ROV in the BGP Default-Free Zone already
is a fact, we made it work! All carriers that keep the Internet
connected together, and care about preventing routing incidents - are
committed to this effort. Thousands of people are now involved at this
point. 

What now remains.. is polishing away some of the sharp edges
[1][2][3][4], and bikeshedding about some of the colors :-)

The below links are like an 'ala carte menu', anyone can engage in
discussions about RPKI at any level they feel comfortable with. Many
people are looking for feedback and input through different forums on
what and how to build it. Pick a platform you enjoy engaging on and
participate (and stick around on this mailing list, all good)! :)

Kind regards,

Job
