Overlapping routes can all match before the longest prefix is chosen.
More than one row can match
The broad rows, the narrow row, and the default row all match this destination.
matching rows=4
The default row is broad
The default row has prefix length 0, so destination AND mask is also all zero.
Matching is not choosing yet
A yes in the match column only says the row is eligible. The next lesson chooses among eligible rows.
eligible rows=4
Summary
The router first recomputes every match row, then chooses the most specific matching prefix.
