This read-only counter reports how many of the entries in a prefix list use a range, ge/le length, match rather than an exact prefix match. An administrator uses it to understand how much of a filtering list relies on range-based matching, which can be more resource-intensive in hardware than exact matches. For example, if a prefix list's overall entry count is high but rlIpPrefListInfoRangeEntries is low, most rules are simple exact-prefix filters rather than broad ranges.
