Note

yabgp is a light weight BGP agent used for connecting network devices. It only can be TCP client in one BGP peering connection and can’t send any update messages by itself(send through REST API). We recommend that each yabgp process connect only one BGP neighbor, so each process is independent with each other, we can start many yabgp processes within the same machine or in different machines. There can be a central controller which can controll all yabgp processes through REST API to send BGP update messages.
