MRT dump file manipulation toolkit (MDFMT) - version 0.2

The MRT routing information export format represents an effective way of storing BGP routing information in binary dump files. Although a few tools exist to extract data from MRT dump files, most of them do not allow repacking or creating such MRT files. The MRT dump file manipulation toolkit (MDFMT) allows to repack parts of large MRT dump files containing BGP update messages into smaller ones, and also allows to create them from Quagga bgpd text log files. The resulting MRT files contain a BGP update sequence of an initial routing table (RIB) propagation followed by the recorded BGP update messages, and may be used for recreating complete BGP sessions based on real data in test setups using the “Update Regenerator” (UR). It also includes a set of smaller scripts to inspect BGP messages within an MRT data set and to aid in operating the UR.
