Many source address validation (SAV) mechanisms have been proposed for preventing source address spoofing. However, existing SAV mechanisms are faced with the problems of inaccurate validation or high operational overhead in some scenarios. This document proposes BGP SAVNET by extending BGP protocol for SAV. This protocol can propagate SAV-related information through BGP messages. The propagated information will help edge/border routers automatically generate accurate SAV rules. These rules construct a validation boundary for the network and help check the validity of source addresses of arrival data packets.
