I follow the steps described in "Ryu SDN fraework, release 1.0" chapter 9.
1)build an environment on Mininet:
ryu@ryu-vm:~$ sudo mn --topo linear,3 --mac --switch ovsk --controller remote -x
2)Set the version of OpenFlow to be used in each router to 1.3.
switch: s1 (root):
root@ryu-vm:~# ovs-vsctl set Bridge s1 protocols=OpenFlow13
switch: s2 (root):
root@ryu-vm:~# ovs-vsctl set Bridge s2 protocols=OpenFlow13
switch: s3 (root):
root@ryu-vm:~# ovs-vsctl set Bridge s3 protocols=OpenFlow13
3)delete the IP address that is assigned automatically on each host
and set a new IP address.
host: h1:
root@ryu-vm:~# ip addr del 10.0.0.1/8 dev h1-eth0
root@ryu-vm:~# ip addr add 172.16.20.10/24 dev h1-eth0
host: h2:
root@ryu-vm:~# ip addr del 10.0.0.2/8 dev h2-eth0
root@ryu-vm:~# ip addr add 172.16.10.10/24 dev h2-eth0
host: h3:
root@ryu-vm:~# ip addr del 10.0.0.3/8 dev h3-eth0
root@ryu-vm:~# ip addr add 192.168.30.10/24 dev h3-eth0
4)Start rest_router on xterm of controller.
controller: c0 (root):
root@ryu-vm:~# ryu-manager ryu.app.rest_router
In this step i got the error mensage attachments.
By the other hands
i started the rest_router in another sesion:
ubuntu@sdnhubvm:~/ryu$ ./bin/ryu-manager ryu/app/rest_router.py
and show the mensage for a successful connection between the router
and Ryu, next:
5)Set the address for each router:
ubuntu@sdnhubvm:~/ryu$ curl -X POST -d ´{"address":"172.16.20.1/24"}’
http://localhost:8080/router
/0000000000000001
[{"switch_id": "0000000000000001",
"command_result": [{
"result": "success",
"details": "Add address [address_id=1]"}]}]
ubuntu@sdnhubvm:~/ryu$ curl -X POST -d ’{"address":
"172.16.30.30/24"}’ http://localhost:8080/router
/0000000000000001
[{"switch_id": "0000000000000001",
"command_result": [{
"result": "success",
"details": "Add address [address_id=2]"}]}]
And the rest of address describe in the chapter.
6)Register as the default gateway on each host.
host: h1:
root@ryu-vm:~# ip route add default via 172.16.20.1
host: h2:
root@ryu-vm:~# ip route add default via 172.16.10.1
host: h3:
root@ryu-vm:~# ip route add default via 192.168.30.1
7)Set the default route for each router.
ubuntu@sdnhubvm:~/ryu$ curl -X POST -d ’{"gateway": "172.16.30.1"}’
http://localhost:8080/router
/0000000000000001
[{"switch_id": "0000000000000001",
"command_result": [{
"result": "success",
"details": "Add route [route_id=1]"
}]}]
And the rest of address describe in the chapter.
8)for s2 router, set a static route to the host (192.168.30.0/24)
under router s3
root@ryu-vm:~# curl -X POST -d ’{"destination": "192.168.30.0/24", "gateway":
"192.168.10.20"}’ http://localhost:8080/router/0000000000000002
[{
"switch_id": "0000000000000002",
"command_result": [
{"result": "success",
"details": "Add route [route_id=2]"}]}]
9)Checking the contents of the setting of each router and every things ok.
And the host can communicate
successfully!!!!
BUT
if i create a enviroment with Miniedit, when start the enviroment and
try to start a xterm for the conrtoller output: "c0 is not in network"
and the rest of configuration (list before) i made from another
terminal sucessful but when i chek the contents of the setting of
each router only the address was added.
and the controller shows a new log mensaje, and the routers are
disconnected randomly. the pings don´t work.
thanks, sorry for the delay , I had problem with internet
