The IESG has approved the following document: - 'IGP Flexible Algorithms (Flex-Algorithm) In IP Networks' (draft-ietf-lsr-ip-flexalgo-16.txt) as Proposed Standard
This document is the product of the Link State Routing Working Group. The IESG contact persons are Jim Guichard, Andrew Alston and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-lsr-ip-flexalgo/ Technical Summary An IGP Flexible Algorithm (Flex-Algorithm) allows IGPs to compute constraint-based paths. The base IGP Flex-Algorithm specification describes how it is used with Segment Routing (SR) data planes - SR MPLS and SRv6. This document extends IGP Flex-Algorithm, so that it can be used with regular IPv4 and IPv6 forwarding. Working Group Summary From the shepherd writeup: We had a great discussion of the use cases and terminology and, as a result, there will be changes in the version submitted for publication. One individual WG member strongly suggested a solution that wouldn't interoperate with routers not supporting Flex Algo. However, it is not uncommon for this WG member to be in the minority. Document Quality From the shepherd writeup: Cisco IOS-XR has an implementation that is shipping for IS-IS. Juniper has an implementation that has not yet shipped. Personnel The Document Shepherd for this document is Acee Lindem. The Responsible Area Director is John Scudder. _______________________________________________ Lsr mailing list Lsr@ietf.org https://www.ietf.org/mailman/listinfo/lsr
