Hello Regis
First of all, your topology is slightly different than that in the lab. In the lab, the connection between R1 and R2 is an Ethernet connection (10 Mbps) as opposed to your FastEthernet connection (100 Mbps). In the lab, this results in having only a single route entered into the routing table for the destination network of 4.4.4.0/24, specifically, the route via R3. This is due to the fact that bandwidth is included in the metric of EIGRP. The bandwidth available via R3 is better than that available via R2, so the route via R3 is preferred.
In your topology, both routes have the same bandwidth and thus have the same metric. EIGRP by default will install both routes in the routing table when the metric is the same. Notice the metric in your sh ip route eigrp output for both routes.
Now this means that the variance command in your case will make no difference, whether it is implemented or not. Variance essentially allows unequal load balancing. If the metric is equal as is the case in your topology, no change will be seen.
In order to recreate the lab identically, you can change the speed of the FastEthernet 0/1 interface on your R1 router to 10. The lab should then work as shown in the lesson.
For more information about the variance feature of EIGRP, take a look at this lesson:

I hope this has been helpful, and I apologize for the late reply. We’ll do our best!
