VRRP Working Group March 2003 San Francisco IETF Mukesh Gupta / Nokia Chair
AGENDA • Introduction and Review Agenda • Milestones/Plans • Current Drafts • Security Issues with VRRP • VRRPv3 • VRRPv3 MIB • IPR Issues • Further Interests of the WG
WG MILESTONES/PLANS • Mar 2003 - Resolve open issues with authentication methods • Mar 2003 - Submit updated version of VRRP (IPv4) for Draft Standard • May 2003 - Submit VRRP for IPv6 (VRRPv3) for Proposed Standard • Jul 2003 - Submit MIB for VRRPv3 for Proposed Standard • Dec 2003 - Review the WG goals and future potential
CURRENT DRAFTS • VRRPv2 (for IPv4) <draft-ietf-vrrp-spec-v2-06.txt> • VRRPv3 (for IPv6) <draft-ietf-vrrp-ipv6-spec-03.txt> Coming Soon: • VRRPv3 MIB • VRRP IPSEC-AH Authentication Specification (???)
SECURITY ISSUES Problem: • Clear text password does not provide much security. • IPsec AH might provide little security but more details need to be specified. • All the security mechanisms make the situation worse in case of mis-configuration. (2 Masters !!) • Still vulnerable to all the LAN attacks Proposed Solution: • Remove the security mechanisms from VRRP and write a good security section • Work on a separate draft for providing IPsec AH security for VRRP (if enough interest in WG ??)
SECURITY ISSUES QUESTIONS The Question: • Anyone against removing security ? Say it Now !! More Questions: (How do we do it ?) • Discourage or Remove fields from the header ? • Backward compatibility issues when removing security ? • Do we need to update the version number ? • Do we need to recycle VRRPv2 through PS again ? • Do we need to update VRRPv2 MIB (RFC 2787) ? • Anything else ???
VRRPv3 • The current draft is draft-ietf-vrrp-ipv6-spec-03.txt • Needs to be reviewed. Did anyone review it ? • Are there any implementations ? Or Plans ? • Can’t move forward without implementation experience !
VRRPv3 MIB • Needed before VRRPv3 draft moves to PS • Kalyan, Kripakaran and Brian have started working on it • New draft instead of updating the existing one • A draft will be submitted to the WG soon • Please review it !!
IPR ISSUES (Cisco) • We found the following statement from Robert Barr, Cisco at http://www.in-addr.de/pipermail/lvs-users/2001-November/004135.html "Cisco will not assert any patent claims against anyone for an implementation of IETF standard for VRRP unless a patent claim is asserted against Cisco, in which event Cisco reserves the right to assert patent claims defensively. If a licensee would prefer a royalty-bearing license, we would make one available." • Robert confirmed this statement in an email again on December 18, 2002 “That is our current position.”
IPR Issues (IBM) • No answer has been received from IBM yet !!
ARE WE INTERESTED IN.. • “IPsec AH Security for VRRP” draft ? available at http://www.keepalived.org/draft-ietf-vrrp-ipsecah-spec-00.txt • Removing Priority value 0 (hold the election now) option ? • Issues and Arguments document ? • Anything else ?
