The IESG has received a request from the Global Routing Operations WG (grow) to consider the following document: - 'Simple Virtual Aggregation (S-VA)' <draft-ietf-grow-simple-va-08.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-06-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The continued growth in the Default Free Routing Table (DFRT) stresses the global routing system in a number of ways. One of the most costly stresses is FIB size: ISPs often must upgrade router hardware simply because the FIB has run out of space, and router vendors must design routers that have adequate FIB. FIB suppression is an approach to relieving stress on the FIB by NOT loading selected RIB entries into the FIB. Simple Virtual Aggregation (S-VA) is a simple form of Virtual Aggregation (VA) that allows any and all edge routers to shrink their RIB and FIB requirements substantially and therefore increase their useful lifetime. S-VA does not increase FIB requirements for core routers. S-VA is extremely easy to configure considerably more so than the various tricks done today to extend the life of edge routers. S-VA can be deployed autonomously by an ISP (cooperation between ISPs is not required), and can co-exist with legacy routers in the ISP. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-grow-simple-va/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-grow-simple-va/ballot/ No IPR declarations have been submitted directly on this I-D.
