Review the device configuration to determine if controls have been defined to ensure the router does not send ICMP unreachable notifications out to any external interfaces.

Verify the "ip unreachables" command is not configured on any external interfaces. Note: the default setting has ICMP unreachable notifications disabled, so if "ip unreachables" is not present in the interface configuration then it is disabled.
