All Prefix-SIDs associated with the Flexible Algorithm are assigned to the same IPv4/IPv6 Prefix. Any Segment Routing network that uses Flexible Algorithm based path computation needs additional details to be carried in the FEC Stack sub-TLV for FEC validaiton. This document updates {[}RFC8287{]} by modifying IPv4 and IPv6 IGP-Prefix Segment ID FEC sub-TLVs to also include algorithm identification.}, }
