mrtparse

Introduction

mrtparse is a module to read and analyze the MRT format data.
The MRT format can be used to export routing protocol messages, state changes, and routing information base contents, and is defined in RFC6396.
Programs like FRRouting, Quagga, Zebra, BIRD, OpenBGPD and PyRT can dump the MRT format data.
You can also download archives from the Route Views Projects, RIPE NCC.

Installation

$ pip install mrtparse

or

$ git clone https://github.com/t2mune/mrtparse.git
$ cd mrtparse
$ python setup.py install

Usage

First, import the module.

from mrtparse import *

or

import mrtparse
And pass a MRT format data as a filepath string or file object to a class Reader().
It is also supported gzip and bzip2 format.
You can retrieve each entry from the returned object using a loop and then process it.

for entry in Reader(f):
    # Parsed data is stored in "entry.data"
    <statements>

We have prepared some example scripts and sample data in "examples" and "samples" directory.
