Ops-GoBGP relaying OpenSwitch and GoBGP. Specifically, you can relay the bgp settings to gobgp that you set in the console of OpenSwitch, and can relay the route that has GoBGP to OpenSwitch.
This page explains how to run Ops-GoBGP. This example have to relay settings and routes between OpenSwitch and Gobgp using Ops-GoBGP in docker container.
Install the docker environment referring to the here.
