Group, Thanks to Karen for preparing good meeting minutes. Let me know if anyone has any comments/correction. I will submit the minutes for the proceedings on Monday, 24th Nov. ======================================================= Virtual Router Redundancy Protocol WG (vrrp) Thursday, November 13, 2003 at 0900-1130 in Rochester Room Chairs: Mukesh Gupta Mukesh.Gupta@nokia.com Radia Perlman radia.perlman@sun.com Minutes taken by Karen O'Donoghue. The chairs provided a proposed agenda as follows: Introduction and Review Agenda VRRP MIB Milestones/Plans Current Drafts' status VMACs vs ND CARP (Common Address Redundancy Protocol) Miscellaneous Issues A discussion of the appropriate approach for the VRRP MIB was led by Kalyan Tata. He presented a summary of the arguments for maintaining a separate MIB for IPv4 and IPv6 or for merging the two MIBs into a single unified MIB for both. Bert Wijnen clarified a misunderstanding on the part of the working group on the meaning of deprecation and the impact on backward compatibility. The consensus of the room was to pursue the unified MIB approach. Mukesh Gupta discussed the current status of the working group efforts including milestones and current drafts. A revised list of milestones based on slight delays in current efforts was presented. VRRPv2 (for IPv4) is in the IESG review process with some minor clarifications being completed. VRRPv3 (for IPv6) needs to resolve the VMAC versus ND issue. The VRRP MIB draft needs resolution of the separated versus unified MIB approaches. With the completion of these remaining work items, the working group needs to consider where to go next. Mark Hollinger led a discussion of the issue of Neighbor Discovery (ND) versus Virtual MAC (VMAC) for VRRPv3. He discussed the historical context of the use of VMAC. He also presented the advantages and disadvantages for using VMAC. A number of scenarios were presented along with the performance of VMAC in each scenario. Finally, a summary list of changes were proposed for the incorporation of ND into VRRPv3. Radia Perlman asked the room who wanted VMAC removed and who wanted ND used instead. Bob Hinden pointed out that a proper evaluation of the ND approach could not be without seeing the actual modifications to the document. Bob Hinden and Mark Hollinger agreed to discuss the details offline. A decision can only be made once a concrete proposal is on the table. Jun-ihiro itojun Hagino from the OpenBSD community presented the common address redundancy protocol (CARP). Points of contact for the effort include mcbride@openbsd and deraadt@openbs.org. The goal of the CARP effort is to have a protocol in this problem space that is completely patent-free. The CARP community has evaluated VRRP and believes both VRRP and CARP do not infringe on any HSRP claims. Bob Hinden questioned the validity of this analysis and whether or not Cisco would agree with that analysis. The primary technical differences between CARP and VRRP were summarized. The discussion evolved back to the topic of patents. Scott Bradner expressed a concern about the CARP community not having discussed their analysis with Cisco. Bob Hinden questioned the mechanics of the reliability mechanism used by CARP. The conclusion of the discussion was that an internet-draft needs to be prepared in order to seriously consider CARP in the context of this working group. The chairs asked if there were any additional topics from the floor. Mark Hollinger asked about the status of the subsecond work discussed at the Vienna IETF. Karen O'Donoghue admitted that she had not completed the draft on this issue in time for the draft cutoff. The routing AD indicated that the BFD (bi-directional forwarding) work being discussed in the routing area should be considered here as well. The routing AD agreed to forward the BFD material to the VRRP WG. The meeting was adjourned. ======================================================= _______________________________________________ vrrp mailing list vrrp@ietf.org https://www1.ietf.org/mailman/listinfo/vrrp
