This read-only Counter reports the number of times this node sent an ICMP redirect message because it found a shorter path to a destination host with the sender's requested type of service. An admin fine-tuning host-level, service-aware routing on this node would watch this counter to verify those specific redirects are actually being sent. For example, a rise in cnticmpOutReServhosts after a targeted QoS change would validate that this node is redirecting the affected sender as intended.
