This read-only Counter reports the number of times this node received an ICMP redirect message because a shorter path to a destination network with a specific requested type of service was found. An admin using type-of-service-based routing policies would watch this counter to see how often ToS-specific route optimizations are being applied for this node's traffic. For example, a rise here after enabling QoS routing policies would confirm those policies are actively triggering redirect-based optimizations.
