The could be talking about 12.3(1) for all we know. Please be more 
specific. I have worked on some extensive bug reviews for 12.3(18)
and while there are still some there it's far from being riddled with
bugs. We take it very serious and there is a lot of work that goes in
to evaluating a release for GD status and 12.3(18) is being evaluated.
We prevented 12.3(17) from getting to that status because of a single
bug we thought was too severe.

I don't and I'd be very amazed if anyone did know it because almost
nobody is running that code on their 75xx's. I'm not trying to
down play your question I'm just giving you the reality of that
code.

12.2 mainline should have it but I don't know about the IRB stuff
with dCEF. We don't recommend anyone doing IRB on a 75xx since
it's not dCEF switched.

12.3(18) should give you all the features and has CEF support
for BVI's at least at the RSP level from what I recall.
