One route is through R1 at 192.168.10.5, and the other route is through R2 at 192.168.10.9. Looking at the topology in Figure 8-15, it might seem as if the path through R1 is the better route because there is a 1544-kb/s link between R3 and R1, whereas the link to R2 is only a 1024-kb/s link. However, EIGRP only uses the slowest bandwidth in its composite metric, which is the 64-kb/s link between R1 and R2. Both paths have the same 64-kb/s link as the slowest bandwidth; this results in both paths being equal.

This is very important, take note on this for equal path calculation
