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`_. .. _RFC6396: https://tools.ietf.org/html/rfc6396 .. _Quagga: http://www.nongnu.org/quagga/ .. _Zebra:

https://github.com/YoshiyukiYamauchi/mrtparse.git $ cd mrtparse $ python setup.py install running install running build running build_py running install_lib copying build/lib/mrtparse.py -> /Library/Python/2.7/site-packages byte-compiling /Library/Python/2.7/site-packages/mrtparse.py to mrtparse.pyc running install_egg_info Writing /Library/Python/2.7/site-packages/mrtparse-0.8-py2.7.egg-info Usage ----- :: from mrtparse import * or :: import mrtparse Programming ----------- 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: We have prepared some example scripts and sample data in `"examples"`_ and `"samples"`_ directory. .. _`"examples"`:
