Psenak, C. Filsfils, S. Litkowski, M. Bocci Status: Standards Track Stream: IETF Date: August 2021 Mailbox: xiaohu.xu@capitalonline.net, sriganeshkini@gmail.com, ppsenak@cisco.com, cfilsfil@cisco.com, slitkows@cisco.com, matthew.bocci@nokia.com Pages: 8 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ospf-mpls-elc-15.txt URL: https://www.rfc-editor.org/info/rfc9089 DOI: 10.17487/RFC9089 Multiprotocol Label Switching (MPLS) has defined a mechanism to load-balance traffic flows using Entropy Labels (EL). An ingress Label Switching Router (LSR) cannot insert ELs for packets going into a given Label Switched Path (LSP) unless an egress LSR has indicated via signaling that it has the capability to process ELs, referred to as the Entropy Label Capability (ELC), on that LSP. In addition, it would be useful for ingress LSRs to know each LSR's capability for reading the maximum label stack depth and performing EL-based load-balancing, referred to as Entropy Readable Label Depth (ERLD). This document defines a mechanism to signal these two capabilities using OSPFv2 and OSPFv3, and Border Gateway Protocol - Link State (BGP-LS). This document is a product of the Link State Routing Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
