* The greater-equal 26 condition specifies that the mask length of matching prefixes must be at least 26 bits .
* If the less-equal parameter is not explicitly defined, the default value is 32 , meaning the longest possible mask length for IPv4.

* greater-equal-value : Specifies the minimum mask length. In this case, the value is 26 .
* less-equal-value : Specifies the maximum mask length. Since it is not explicitly configured, the default value is 32 .
