[routing-wg]virtual aggregatio in ietf
by Paul Francis 20 Jul '08

20 Jul '08

Gang, I have submitted an internet-draft to the IDR group on virtual aggregation (VA) (http://www.ietf.org/internet-drafts/draft-francis-idr-intra-va-00.txt). This draft suggests a few changes to routers that allow operators to control the size of their FIBs, shrinking them by 5x or 10x quite easily. This would extend the lifetime of routers that are constrained by FIB size. There has been a lively discussion of this on the IDR mailing list, including a suggestion that FIB reduction is more important for lower tier ISPs (tier 2, tier 3...) than for tier 1 ISPs. Unfortunately I don't think that people from smaller ISPs pay much attention to the IDR mailing list, so they are not being represented in this discussion. So I'm looking for input from folks who think that FIB reduction helps them, so as to better understand their requirements. Any help is much appreciated. Thanks, PF
