                        draft-ietf-savi-dhcp-13

Abstract

   This document specifies the procedure for creating bindings between a
   DHCPv4/DHCPv6 assigned source IP address and a binding anchor 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 in DHCP scenario.  This mechanism is proposed as a
   complement of ingress filtering to provide finer granularity source
   IP address validation.
