Hello Fred,

Not supporting BMP is not a Defect .. it is a Feature :)
Change the type from defect to enhancement :)

A basic daemon, called ExaBMP, was created to parse BMP messages for inet.0 routes. It currently prints parsed route sent using draft-1 is out, which is what the latest JunOS version seeems to send.

the daemon is undocumented but the following environment variables can be used :
exabmp.bmp.host - IP to listen on
exabmp.bmp.port - port to listen on
exabmp.bmp.json - print json representation of the route (default) or textual ones
exabmp.bmp.asn4 - will the routes received be from peer supporting 32 bits ASN.

The data is sent to FD3, which is a copy of FD2, so you should be able to redirect it using normal unix pipe command ..

The issue with draft one, is that no information about the negociated OPEN for each peer is sent, so parsing the route can not be done without indicating to the daemon what to expect, and as each peer can have different negociated capabilities, it is no reliable, should any of your peer changed its configuration.

This issue was resolved in the latest draft, but this is not what is implemented by JunOS ... I will invest more time in the development of this deamon once JunOS implement the latest draft, which is way better (like making sure it can fork helper process, like ExaBGP).

For information other projects exists (I would not use them more than ExaBMP). https://github.com/forhadahmed/bmp : implemented the latest draft, it seems to be a nicely written and well maintained implementation .. https://code.google.com/p/bmpreceiver/ and https://github.com/garberg/bmpd implemented earlier draft too and are suffering the same issues as ExaBMP.

Let me know if you encounter any issue and I will look into it. Please update this issue if needed.

Looking forward for some nice ales with you :)

Thomas
