Abstract

   This document specifies the procedure for creating bindings between a
   DHCPv4 [RFC2131]/DHCPv6 [RFC3315] assigned source IP address and a
   binding anchor [I-D.ietf-savi-framework] on SAVI (Source Address
   Validation Improvements) device. The bindings can be used to filter
   packets generated on the local link with forged source IP address.
