Is there a reason for this slow-path routing of ICMP?
They thought they needed to inspect/act on some/all ICMP traffic at the time they designed the forwarding ASIC, so they just punted all ICMP to CPU.
These platforms have other shortcomings from being designed in the late 90:ties, but I know people who still have them in production because if you don't have too many flows (they have a per-destination based forwarding cache), they still work fairly well.
