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!
