Abstract

   This document specifies the procedure for creating bindings between a
   DHCPv4/DHCPv6 assigned source IP address and a binding anchor on a
   SAVI (Source Address Validation Improvements) device.  The bindings
   can be used to filter out packets with forged source IP address in
   DHCP scenario.  This mechanism is proposed as a complement to ingress
   filtering to provide finer granularity source IP address validation.
