I have some concern of the bullet (2) (Addition of optional support for ARP / Neighbor Discovery optimization) to be added to TRILL re-charter work list. ARP is for resolving MAC address from host's IP address. It is not specific to TRILL. Straight Ethernet needs ARP. Donald's new draft on ARP optimization (http://pothole.com./~dee3/drafts/draft-eastlake-trill-rbridge-arp-xx.txt) describes a generic ARP proxy procedure, i.e. changing an ARP broadcast msg to a unicast msg if the target IP is cached in its local cache. Otherwise do nothing. ARP proxy function should be allowed on any device. As a matter of fact, ARP proxy has been deployed in many places. When ARP proxy is enabled on any devices, RBridge should treat the ARP Broadcast or unicast messages same way as all other IEEE802.1Q data frames. No special processing should be needed by RBridge for ARP messages. If an Rbridge needs to add ARP proxy function on some ports, it is exactly same as RBridge having standard IEEE802.1Q functions on some ports. But TRILL doesn't need to re-define IEEE802.1Q, does it?

Subject: [rbridge] Updated charter Based on the comments on the mailing list, here is the updated charter. Description of Working Group: The TRILL WG has specified a solution for shortest-path frame routing in multi-hop IEEE 802.1-compliant Ethernet networks with arbitrary topologies, using an existing link-state routing protocol technology and encapsulation with a hop count. [Add reference to RFC?] The current work of the working group is around operational and deployment support for the protocol. This includes a MIB and other pieces needed for operations, but also additional ways to extend and optimize TRILL for the properties of the networks on which it is deployed. The WG will work on the following items: (1) A MIB for TRILL which specifies the unique pieces needed for the protocol while reusing what is in the IS-IS MIB and the IEEE 802.1 MIB modules for pieces that are not unique to TRILL. (2) Addition of optional support for ARP / Neighbor Discovery optimization. (3) Refinement of the TRILL Header Options feature and specification of an initial base set of options. (4) Support for RBridge campus VLAN regions, such that the same VLAN ID can have different meanings in different regions, requiring configuration only at border RBridges. (5) Write up how Operations and Management (OAM) will be handled in networks using TRILL. (6) Determine how TRILL will provide improved support for data centers such as support of the IEEE 802.1 "Data Center Bridging" standards. (7) Document interoperability test results of protocol implementations. Goals and Milestones: Done - Accept base protocol specification as a WG document Done - Accept problem statement and applicability as a WG work item Done - Start work with routing area WG(s) to undertake TRILL extensions Done - Accept architecture document as a WG work item Done - Accept routing protocol requirements as a WG work item Done - Choose routing protocol(s) that can meet the requirements Done - Submit problem statement and applicability to IESG for Informational RFC Done - Submit base protocol specification to IEEE/IETF expert review Done - Base protocol specification submitted to the IESG for publication as a Proposed Standard RFC Done - First draft showing what is needed for MIB NEW: Done - Initial WG draft on VLAN Mapping Done - Initial WG draft TRILL Header Options Jul 2010 - Initial WG draft on ARP/ND optimizations Aug 2010 - Submit TRILL Header Options to IESG for publication as Proposed Standard Aug 2010 - Submit Rbridge Campus VLAN Regions to IESG for publication as Proposed Standard Oct 2010 - Submit RBridge MIB to IESG for publication as Proposed Standard Oct 2010 - Initial WG draft for RBridge support of Data Center Bridging Oct 2010 - Initial WG draft on RBridge OAM Jul 2011 - Re-charter or shut down the WG _______________________________________________ rbridge mailing list rbridge@postel.org http://mailman.postel.org/mailman/listinfo/rbridge _______________________________________________ rbridge mailing list rbridge@postel.org http://mailman.postel.org/mailman/listinfo/rbridge
