It seems I have problem with the STP.
It is not a trunked link.
I have two catalysts connected via cross calble (fastethernet 0/24) and both
of them are connected to a 7206 (fastethernet 0/1) via BVI interface.
If a set  the fastethernet 0/24  in bloking (as per James.Kilby  suggestion,
thanks) I resolve the problem, but it's just a workaround  and not a
solution.
By the way I don't understand why I have this loop: I have the same HW/SW
configuration is  5 sites and only in this one I'm experiencing this problem.

Have a nice day to all,
Teresa

  If this a trunked linked, make sure you manually set the parameters on each
  end, no auto.  Also, I have seen some servers with teamed nic's try to
  etherchannel and it will flap like that unless the switch is also
configured
  for it.  Hope this helps.
