An IP prefix list is configured on a router using the following command:ip ip-prefix huawei...

1. Understanding Prefix List Configuration:

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 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.

2. Explanation of Values:

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 .

3. Summary:

greater-equal-value = 26

less-equal-value = 32
