Looking for an agent on Linux that will render YANG models, so I can provision networking on Linux. Danke, Karl On Fri, Jul 27, 2018 at 11:25 AM, Wes Felter <wmf@felter.org> wrote:

It's not clear what problem you're trying to solve, but http://www.clicon.org/ might do what you want.

I am unaware of any open source software that implements a complete solution for parsing the YANG into a model, allowing the manipulation of that models data, and configuring the system to match that model.

pyangbind (https://github.com/robshakir/pyangbind) can be used to generate Python classes that you can bind data to. This isn't Linux-specific, but it is possible to input a YANG model, and some external data, and produce a usable Python data structure. napalm-yang (https://github.com/napalm-automation/napalm-yang) is an example of doing this via NAPALM output via profiles that handle the parsing to/from device native data structures, with differing levels of support: https://napalm-yang.readthedocs.io/en/latest/root/supported_models/index.htm... -- Brandon Ewing (nicotine@warningg.com)

Could you define "render"? If you're looking to take a YANG model (which one?) and configure Linux kernel networking features with it, I can't recall having seen something that does this. I have been working on a side project (which I'm hoping to bring to a hackathon) to take Linux networking and map it to OpenConfig - but this is maexceptionally embryonic. If you're looking for ways to manipulate data instances for YANG-modelled schemas on Linux, here are some options (full disclosure: I lead the development of two of them): - ygot - produces Go structs, or Protobufs that correspond to a YANG model - github.com/openconfig/ygot - pyangbind - produces Python classes that correspond to a YANG model - github.com/robshakir/pyangbind - ydk (Cisco) - produces Python and C++ APIs, more centred around device interaction (https://developer.cisco.com/site/ydk/) Cheers, r.

Maybe looking at this one: http://yuma123.org/wiki/index.php/Yuma_netconfd_Manual -- Make sure your code "does nothing" gracefully. - The Elements of Programming Style (Kernighan & Plauger)

What you want is probably sysrepo https://github.com/sysrepo/sysrepo /Eric On 08/09/2018 03:56 AM, Marcus Leske wrote:

Yes Rob, i’d like to do what you described: use netconf and yang to provision the quagga BGP implementation.

Can you describe work arounds? If any.

Can i convert a bgp yang model to json/yaml and have some other app consume it?

Thanks
