mrtparse

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 Quagga / Zebra, BIRD, OpenBGPD and PyRT can dump the MRT format data.

You can also download archives from the Route Views Projects, RIPE NCC.

Python2 or Python3 or PyPy or PyPy3

$ pip install mrtparse

$ git clone https://github.com/YoshiyukiYamauchi/mrtparse.git

$ python setup.py install

from mrtparse import *

import mrtparse

First, import the module.

from mrtparse import *

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.

d = Reader(f)
for m in d:
    <statements>

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