Multi-Threaded Routing Toolkit (MRT) Border Gateway Protocol (BGP)
Routing Information Export Format with Geo-Location Extensions
Abstract
This document updates the Multi-threaded Routing Toolkit (MRT) export
format for Border Gateway Protocol (BGP) routing information by
extending it to include optional terrestrial coordinates of a BGP
collector and its BGP peers.

1. Introduction
Researchers and engineers often wish to analyze network behavior by
studying routing protocol transactions and routing information base
snapshots in relation to geographical topologies. Usually, the
Border Gateway Protocol [RFC4271] is the subject of study, and the
analysis can be significantly aided by the availability and extension
of the "Multi-Threaded Routing Toolkit (MRT) Routing Information
Export Format" [RFC6396]. The MRT format was originally defined in
the MRT Programmer's Guide [MRT-GUIDE].
The addition of geo-location coordinates (longitude and latitude)
pertaining to the geographical location of both the BGP collector and
its BGP peers to BGP export data enables a researcher or enquiring
individual to gain a terrestrial insight to the routes seen by a BGP
speaker. Such data may ultimately aid researchers in understanding
any disparity between the geographical location of networks and the
topological location of networks in addition to the relationships
between geographical position and routing anomalies. Such insight
could provide future input into network design and network security.
This memo documents an optional extension to the MRT format [RFC6396]
and introduces an additional definition of an MRT Subtype field that
includes the terrestrial coordinates of a BGP collector and its BGP
peers.
