Hi Håvard, Oh, Zebra daemon is also running?
Ryu's Zebra protocol "server" service will perform as Zebra daemon against the other Quagga daemons (e.g., OSPFd, BGPd). You don't need to start "/usr/lib/quagga/zebra". Say Zebra daemon as "server" and the other Quagga daemons as "client" (which means OSPFd is a client side application against Zebra daemon; - "ryu/services/protocols/zebra/server" provides the "server" side application framework - "ryu/services/protocols/zebra/client" provides the "client" side application framework Thus, you need to start Zebra daemon if you use "ryu/services/protocols/zebra/client", but don't need to start Zebra daemon if you use "ryu/services/protocols/zebra/server".
