Any info on devices that are running eBGP on the Internet?

["Compton, Rich A" <Rich.Compton () charter com>]

Hi, I am working with MANRS (https://www.manrs.org) on a tool for checking router configs for BGP security / spoofing 
prevention (e.g. uRPF) https://github.com/manrs-tools/MANRS-validator
We are wondering if there is any research on the percentages of different types of devices running BGP on the Internet.
Something like:
Cisco IOS 30%
Junos 30%
Mikrotik 20%
etc…
We are looking to focus our tool on the most prevalent types of devices doing BGP (and the most prevalent with BGP 
security/spoofing issues) so that we can have the greatest impact.  Does anyone have any information on this or know 
where I can obtain this information?  Thanks in advance!
