Technical Summary

In networks that use multiple techniques for address assignment, the appropriate Source Address Validation Improvement (SAVI) methods must be used to prevent spoofing of addresses assigned by each such technique. This document reviews how multiple SAVI methods can coexist in a single SAVI device and collisions are resolved when the same binding entry is discovered by two or more methods.
