Abstract
This draft proposes a new intra-domain Source Address Validation (SAV) solution. This solution leverages the Bidirectional Metric- based Shortest Path First (BM-SPF) mechanism to avoid the complexity introduced by asymmetric routing for source address validation. It allows intra-domain routers to generate directly the SAV rule from the router's FIB table, based on the reality that the source and destination interface will be same if the IGP domain is symmetric assured.
