     I've seen these, too, after the we uograded the MSFC to an image
     that has SSH support and SSH was switched on. I managed to get
     rid of these messages by switching ISAKMP off.

     msfc(config)#no crypto isakmp enable

     I don't know the cause. I assume that when the cryptographic keys
     are generated some cryptographic features are enabled at the same
     time. Why the router sees the ISAKMP/IKE packets in the first
     place or does it even see them is a completely different
