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.
