Rojarek, the 7600 is an enormously complicated device and you have provided
no details to work with, so it's impossible to debug your problems without
more information.  Are you pinging the remote c7600? Do you have CEF
enabled?  Are you within limits for tcam usage?  what line cards are you
using?  What's the CPU usage on each RP?  Do you have CoPP enabled? etc,
etc, etc.
