Folks,
One of the items that was discussed during the working group meeting
in Amsterdam was the relative benefits of using asplain, asdot or
asdot+ to represent four byte autonomous system numbers. The chairs
feel that the discussion tended towards favouring asdot/asdot+, which
is already used relatively widely, but with the note that people do
need to review their in-house tools and scripts to ensure they will
work with numbers expressed in this notation.
Cheers,
Rob
