If greater-equal is specified but less-equal is not in IP prefix configuration, what is the IP prefix range?

In IP prefix configuration, specifying a greater-equal value sets a minimum length for the prefix, meaning that the prefix length can be greater than or equal to this specified value. Since the less-equal parameter is not specified in this case, there is no upper limit on the prefix length.

Therefore, using a greater-equal value as a starting point and recognizing that IP prefix lengths can extend up to the maximum allowable length of 32 bits in IPv4, the correct range for the IP prefix is from the greater-equal value up to 32. This means any prefix length that is equal to or longer than the specified greater-equal value is valid, making the range [greater-equal-value, 32] accurate.

This choice correctly reflects that while there is a minimum constraint set by greater-equal, there exists no upper constraint limiting the prefix length to values below 32 bits, therefore allowing all prefix lengths from the specified value up to the maximum of 32 bits.
