I have avoided the longer thread, so I thought replying to yours
might be a better option.
I think the discussion of what to do with 240.0.0.0/4 is premature.
We need to get the code fixed, that is the most important item at
this time. When we get closer to needing 240.0.0.0/4 we can evaluate
at that time how much of the code has been fixed, and what the risk
is to deployment. By the time we need it we may find 95% of the
devices have been fixed, or we may find 5%. The problem is we
neither know the timeframe in which we need it, nor do we know how
fast vendors can get it fixed.
In order to have the most options I applaud Vince for running this
through the IETF, and I would ask everyone on this list to make it
a checklist item for your very next vendor meeting. This is a small
change, vendors will make it, but only if customers ask for it.
Ask for patched software today and we'll be much better off tomorrow.
