Subject: [rfc-dist] RFC 6148 on DHCPv4 Lease Query by Relay Agent Remote ID
Message-ID: <20110301024907.74DA9E0736@rfc-editor.org>
A new Request for Comments is now available in online RFC libraries. RFC 6148 Title: DHCPv4 Lease Query by Relay Agent Remote ID Author: P. Kurapati, R. Desetti, B. Joshi Status: Standards Track Stream: IETF Date: February 2011 Mailbox: kurapati at juniper.net, ramakrishnadtv at infosys.com, bharat_joshi at infosys.com Pages: 13 Characters: 26185 Updates: RFC4388 I-D Tag: draft-ietf-dhc-leasequery-by-remote-id-09.txt URL: http://www.rfc-editor.org/rfc/rfc6148.txt 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 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 to and from the clients. In certain scenarios, this model is not scalable. This document first looks at issues in the existing mechanism and then proposes a new query type, query by Remote ID, to address these issues. [STANDARDS-TRACK] This document is a product of the Dynamic Host Configuration Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.
