Hi Alaerte, This will be dependent on the hardware, traffic types, throughput and software version/configuration. You may need to explain a little more in order to get an adequate answer to your question.
Large numbers of packets from a handful of hosts running PMTUD may require a smaller number of ICMP notifications than would be necessary for a larger number of hosts sending less traffic. The difference in the MTUs, and the sizes of the incoming packets will also affect the proportion of traffic which triggers notifications. Similarly protocols running on the router itself may require their packets to be fragmented. Paul.
