A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Global Routing Operations Working Group of the IETF. Title : Simple Virtual Aggregation (S-VA) Author(s) : Robert Raszuk Jakob Heitz Alton Lo Lixia Zhang Xiaohu Xu Filename : draft-ietf-grow-simple-va-11.txt Pages : 9 Date : 2012-07-31 Abstract: All BGP routers in the Default Free Zone (DFZ) are required to carry all the routes in the Default Free Routing Table (DFRT). A technique is described that allows some BGP routers not to install all of those routes into the Forwarding Information Base (FIB). Some routers in an Autonomous System (AS) announce an aggregate (the VA prefix) in addition to the routes they already announce. This enables other routers not to install the routes covered by the VA prefix into the FIB as long as those routes have the same next-hop as the VA prefix. The VA prefixes that are announced within an AS are not announced to any other AS. In contrast to VA, S-VA reduces operational complexity by proposing local to given BGP speaker solution without any dependency on network wide configuration or requires presence of any form of intra-domain tunneling.
