I'm not really sure what the hold-up is, but I know Mikael, together
with the good folks at netDEF (Martin and Alistair) are working hard on
fixing these issues. While I have not had much time to provide them with
feedback on their progress, it is high on my agenda - not to mention
funding support for them will only help the cause.

Well, on the basis that an attack is made easier if you are running
IS-IS on a vulnerable interface, in theory, an attack would be highly
difficult if a vulnerable interface were not running IS-IS to begin with.

But I do not have any empirical data on any attempts to attack IS-IS,
successfully or otherwise. So your guess is as good as mine.

Mark.
