pyats-napalm
An example showing how I managed to implement pyats to use Napalm instead of Genie/Unicon to connect to a Juniper device and run a check. We are testing this at Ting Fiber. The lack of BGP parsers for Junos in the native distribution made me search around for some other option vs writing our own.
The check I reimplemented was originally written by Kevin Corbin.
Flaws:
- The router password doesn't load from the Testbed file, so I have hard coded it for this example
- The napalm connection object sits in the very handy 'custom' pyats Device dictionary
As a proof of concept it works well
