This document proposes a simplified method for advertising a large number of SRv6 SIDs. This method is particularly useful in scenarios that require generating many END.X SIDs, such as when supporting numerous Flex-Algo algorithms. It helps reduce the size of LSDB advertisements and improves IGP advertisement efficiency and operational performance.}, }
