draft-manderson-grow-geomrt-00 - Terry M presenting draft on geo mrt - extension to mrt format - 3 people read draft - introduce mrt type field and related sub fields - one suggestion to escalate collector gps coord. outside of the bgp format - table type number 65 - okay or use different number? - suggestion to petition IANA for number - implementaion example presented - Demonstration of implementation with Zebra - code diffs will be made available at some point - suggestion made to be able to get geo location from dns - polled room...3 interested - Interest in this document - going to list draft-jasinska-ix-bgp-route-server - Elisa presenting draft - description of what an IXP is - n*(n-1)/2 bgp sessions where n is number of routers at exchange - proposing route-server system - multilateral interconnect with route-server - immediate dense interconnection - 3 open source implementation but no reference or documentation - - operations considerations included in draft - RFC 1863 not mentioned in draft, should be - Danny commented rfc1863 should be referenced route server - concern if people want to implement static configurations - filter peers plan to implement sidr origin info. issue with prefix filtering off irr's - Jeff ? suggestion - dig up original route server drafts, don't even think about route reflector - contact merit, last operator of route servers rt config software mode specifically for building view base policies. - question: if i want to filter prefixes, how do i know what AS they connect to? - suggestion made that 1863 is not relevant - rtconfig can be used for filtering - author thinks RPSL is out of scope - - question: how does one implement max prefix in this model? do we trust route-server - route-server implements max-prefix on the server side - can get statistics from route-server about number of prefixes announced - everyone agrees better protection on the bgp sessions would be great - currently informational draft, can talk about this further and will need to talk to IDR about updating bgp spec - Eduardo ?? - runs route service, going to double size in Brazil - is looking for other implementations draft-ietf-grow-diverse-bgp-path-dist-02 - RObert Raszuk presenting update on draft - intended to be informational, no changes to any protocols - fully backward compatible with current RR deployment - presented deployments models - today only get 1 best path - with diverse path you can get N paths - model 1 - disable med check on best path selection - model 2 - add additional session to announce 2nd path - works in standard IP and MPLS networks - works with any AFI/SAFI - open issues: - memory concerns on clients - not unique to this technique...anything that sends more paths will have this - question: are they changing bgp path selection? - no, hacking existing system to forward non-best paths - wait till beijing for last call - John Scudder - asked in your closing remarks, prefer to last call after implemenation VA - main drafts: (No IPR associated with them) - draft-ietf-grow-va-02 - draft-ietf-grow-simple-va-00 - auto-config draft - draft-ietf-grow-va-auto-01 - no implementations at this point - should we move main drafts to information rfc? - no comments, taking to the list - auto-config draft - draft-ietf-grow-va-auto-01 - completely optional - move to informational? - no comments draft-uzmi-smalta-00 - aggregation work introduced at ietf 76 - presented outling of fib aggregation draft - level 1-4 aggregation - smalta has level 5 agg - better agg - no extra routable space - comparable update processing - presented comparative summary - 39% compression, 10% more than level 2 - presented basic idea of fib aggregation - level 1 and level 2 are similar, level 1 drops specifics, level 2 combines specifics - smalta exploits all methods - explanation how it works - - how far aggregated after N updates - loses 1-6% of fully-aggregated state - how many rib-to-fib downloads per update - each update may result in ust one change in original table - rib-to-fib downloads exactly 1 with no agg, 0,1, or more with aggregation - Danny McPherson: using live data or a snapshot of routing table - using snapshot and applying updates to do analysis - smalta one shot aggregation takes 300-400ms - 3-4x more processing than L1 and L2, applied very infrequently - smalta update same processing time as L1 and L2 - fewer avg rib-to-fib downloads in smalta - question about analysis, do the numbers remain over longer periods? - Demetre - when you increase the period do you know how the deteriation of gain would be? - expect to lose more of aggregated state over a longer period - Comment - Longer time period could show different results. Day to day patterns also change. If you look at larger sample of routers compression could change. - lixia agrees different time periods could effect data - waiting for new combined draft before taking it further
