The command ip ip-prefix huawei index 10 permit 10.1.1.0 24 greater-equal 26 defines a prefix filter:
The base prefix is 10.1.1.0/24.
The greater-equal 26 condition specifies that the mask length of matching prefixes must beat least 26 bits.
If the less-equal parameter is not explicitly defined, the default value is32, meaning the longest possible mask length for IPv4.
2. Explanation of Values:
greater-equal-value: Specifies the minimum mask length. In this case, the value is26.
less-equal-value: Specifies the maximum mask length. Since it is not explicitly configured, the default value is32.
3. Summary:
greater-equal-value = 26
less-equal-value = 32
