A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Dynamic Host Configuration Working Group of the IETF. Title : DHCPv4 lease query by Relay Agent Remote ID Author(s) : P. Kurapati, B. Joshi Filename : draft-ietf-dhc-leasequery-by-remote-id-07.txt Pages : 18 Date : 2010-10-08 Some Relay Agents extract lease information from the DHCP messages exchanged between the client and DHCP server. This lease information is used by relay agents for various purposes like antispoofing and prevention of flooding. RFC 4388 defines a mechanism for relay agents to retrieve the lease information from the DHCP server as and when this information is lost. The existing lease query mechanism is data driven, which means that a relay agent can initiate the lease query only when it starts receiving data from/to the clients. In certain scenarios, this model is not scalable. This document first looks at issues in existing mechanism and then proposes a new query type, query by Remote ID, to address these issues.
