Explanation

The destination address 192.168.20.108 falls within the 192.168.20.96/28 network (range: 192.168.20.96–192.168.20.111), making /28 the correct subnet mask for the matching route. The /29 represents the subnet mask of the next most specific route (192.168.20.96/29, range .96–.103), but longest-prefix match selects /28 as it is more specific and still contains .108. The administrative distance for this route is 90 (EIGRP) and the metric is 40, which are the routing table components associated with this matched entry.
