Zusammenfassung:	Systems and methods for the storing and distribution of routes with different length prefixes between different tables in network devices utilizing lookup strengths associated with prefix lengths are disclosed. The results from performing lookups in these tables may have associated lookup strengths based on the prefix length of the associated routes, and the evaluation of which route to utilize for packet processing can be determined utilizing these associated lookup strengths. In this manner, a desired route for such packet processing may be determined regardless of the table where a route resides.
