Underlay Path Calculation Algorithm and Constraints for Bit Index Explicit Replication
RFC 9272, “Underlay Path Calculation Algorithm and Constraints for Bit Index Explicit Replication”, is a Proposed Standard document published in September 2022 by Z. Zhang, T. Przygienda, A. Dolganow, H. Bidgoli, IJ. Wijnands, A. Gulko. It updates RFC 8401, RFC 8444. The canonical text is published by the RFC Editor.
Abstract
This document specifies general rules for the interaction between the BIER Algorithm (BAR) and the IGP Algorithm (IPA) used for underlay path calculation within the Bit Index Explicit Replication (BIER) architecture. The semantics defined in this document update RFC 8401 and RFC 8444. This document also updates the "BIER Algorithm" registry established in RFC 8401.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
