Two keywords can be optionally appended to a prefix list entry: le (less than or equal to) and ge (greater than or equal to). Without either, an entry will match an exact prefix. The le parameter can be included to match all more-specific prefixes within a parent prefix up to a certain length. For example, 10.0.0.0/24 le 30 will match 10.0.0.0/24 and all prefixes contained therein with a length of 30 or less.
We can use le to create an entry to match “any” prefix: 0.0.0.0/0 le 32 matches any prefix with a length between 0 and 32 bits (inclusive). This matches all possible IPv4 prefixes.
