> existing/routed/old/stable prefixes run at the same time, to filter out the
> remote-end reachability problems and hopefully leave us with /28-nonpropagate
> ping tests of this kind are incomplete. we also need to institute ping and

much of this has been been done. see nick's stuff, our paper last inm,
the cool one at the app level from last janog and apricot, some renesys
work in the area, ...
but what is this gonna tell you? what is in place today. bit whoopie doo.
just as with the 2050 /19 agreement in danvers, filtering policies will
adjust to allocation realities if honestly negotiated and technically
so do not base all future technology and policy on yesterday's ephemeral
router configs. otoh, do make tools to prevent, diagnose, and fix
