Abstract
In one embodiment, a technique is used by a routing system to generate a link state identifier for a link state advertisement message. The routing system generates the link state advertisement message. A prefix length is read from the link state advertisement message. Further, a prefix is read from the link state advertisement message. A hash function is performed on the prefix and the length to produce a result by appending the length to the prefix to generate a combined value, inputting the combined value to a hash algorithm, and using at least a portion of an output of the hash algorithm as the result. The link state identifier is determined from the result of the hash function.
