Test SDN IP

After few seconds after we start ONOS and create our mininet topology.

Use routes command in ONOS console, should get all network routes (might be different between Quagga and GobGP version)

onos> routes
   Network            Next Hop
   192.168.4.0/24     192.168.3.11   
   192.168.5.0/24     192.168.2.11   
Total IPv4 routes = 2

   Network            Next Hop
Total IPv6 routes = 0

In mininet, we can use hostname ip route command to get routing table in router.

mininet> quagga1(or gobgp1) ip route
192.168.1.0/24 dev quagga1-eth0  proto kernel  scope link  src 192.168.1.11
192.168.2.0/24 dev quagga1-eth1  proto kernel  scope link  src 192.168.2.10
192.168.4.0/24 via 192.168.1.12 dev quagga1-eth0  proto zebra
192.168.5.0/24 via 192.168.2.11 dev quagga1-eth1  proto zebra
mininet> quagga2(or gobgp2) ip route

192.168.4.0/24 via 192.168.3.11 dev quagga2-eth1  proto zebra
192.168.5.0/24 via 192.168.1.11 dev quagga2-eth0  proto zebra
mininet> kreonet ip route
192.168.2.0/24 dev kreonet-eth1  proto kernel  scope link  src 192.168.2.11
192.168.4.0/24 via 192.168.2.10 dev kreonet-eth1  proto zebra
192.168.5.0/24 dev kreonet-eth0  proto kernel  scope link  src 192.168.5.1
mininet> amlight ip route
192.168.3.0/24 dev amlight-eth1  proto kernel  scope link  src 192.168.3.11
192.168.4.0/24 dev amlight-eth0  proto kernel  scope link  src 192.168.4.1
192.168.5.0/24 via 192.168.3.10 dev amlight-eth1  proto zebra

In mininet, we can use host khost from kreonet to ping ahost from amlight.

mininet> khost ping -c4 ahost
PING 192.168.4.10 (192.168.4.10) 56(84) bytes of data.

--- 192.168.4.10 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3001ms
rtt min/avg/max/mdev = 0.077/0.381/0.906/0.338 ms

Also, we can use iperf to test network.

mininet> ahost iperf -s&
mininet> khost iperf -c ahost

And we can see traffic generated by iperf, from KREONET to AmLight
