Massimo -

Is this the patch you used?
IX84533 - Disappearing of admin interfaces when status changes.

It is something like: you double click on a router, you first see all
interfaces and then they disappear while you
are looking at them and they never come back ?
I had the same problem in a couple of installations. I had to call the
support and they gave me a fix
for ipmap that solved the problem.
Call your nearest support centre.
Hope this helps
