I don't think that the problem is in the GEANT's infrastructure because the 
CESNET node can reach 10.0.0.1 just fine:

In fact, 10.0.0.1 is visible within the trace towards 10.0.3.45 -- see hop 
#10:

Despite that, I cannot ping 10.0.3.45 from 10.0.96.132. I can ping 
10.0.0.1, though.

With kind regards,
Jan
