ryu.service.protocol.bgp.application

This application provides a convenient way to speak BGP protocol.

It reads a configuration file which specifies neighbors, routes and some other settings. ryu/service/protocols/bgp/bgp_sample_config.py is a sample configuration file for this application. Configurable items and descriptions are written in this sample.

Launch the speaker:

ryu-manager ryu/service/protocols/bgp/application.py --bgp-app-config-file ryu/service/protocols/bgp/bgp_sample_config.py

It also provides an SSH interface. You can see the RIB and do some operations via this. SSH port and username/password can be configured by the configuration file. You can check the help by hitting ‘?’ key in this interface.

Example:

$ ssh localhost -p 4990
