The IESG has approved the following document: - 'Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format with BGP Additional Paths Extensions' (draft-ietf-grow-mrt-add-paths-03.txt) as Proposed Standard This document is the product of the Global Routing Operations Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-grow-mrt-add-paths/ Technical Summary The MRT (RFC6396) record format is used to for archive routing information as it changes over time. BGP is one of the routing protocols supported and MRT needs updates when BGP gets certain new capabilities. The capability for BGP to advisertise multiple paths has been added with RFC7911. This document adds the required functionality to MRT enabling the format to store the new information. Working Group Summary There has been good consensus within the working group. The draft overall is straight forward, and simple. The document is required to ensure that MRT can continue to store BGP routing information that vendors are implementing and end users are deploying. The last call was quiet, but it was clear from the interested parties that the document was ready for publication. Document Quality The feature has been implemented in bird (http://bird.network.cz/) and is waiting to be pulled into an official release. There are two software packages for procesing the MRT data, RIPE NCC's bgpdump, and java-mrt (https://github.com/tking/java-mrt). The document focuses on extending the existing MRT standard, by adding new message subtypes. Personnel Document Shepherd: Peter Schoenmaker Responsible Area Director: Joel Jaeggli
