Actually there is. Any decent networking gear is going to do ip
routing by building forwarding tables in hardware or be using MPLS
anyway. A icmp packet addressed to the router itself is going to cause
an interrupt for main processor and be queued to be dealt with later
or even dropped if the device is under load. You can see this in
traceroutes where the response time and/or packet loss from
intermediate nodes is higher than the response time/ loss of the
