Hi,

You need to write the configuration for your bgp routers, I think
bgp_sample_conf.py includes everything you need, all you need is to modify
values in that configuration

After that, you can run Ryu bgp application directly in two network
namespace with two configuration.

I never try Ryu BGP application before, for more information, please follow
instruction here:
https://ryu.readthedocs.io/en/latest/app/bgp_application.html
