No I did not use any dhcp. In an another different attempt, I created three machines one is controller and the rest two act as switches. Each switch has two interfaces with the one interface it is connected to the controller and another is used for switch port. Following are my configuration: 1. Controller IP 192.168.0.1/24 and pox controller is running inside it with the misc.of_tutorial (hub) application 2. Switch PC 1 eth0 IP: 192.168.0.2/24. I attached eth1 with the ovs bridge using commands: a. sudo ovs-vsctl add-br br0 b. sudo ovs-vsctl add-port eth1 c. sudo ifconfig eth1 0 d. sudo ifconfig br0 10.10.1.2 netmask 255.255.255.0 e. sudo ip tuntap add mode tap veth0 (Created this for connecting a VM1 on switch PC1 with IP 10.10.1.21 with veth0 interface ) f. sudo ip link set veth0 up g. sudo ovs-vsctl add-port veth0 h. sudo ip tuntap add mode tap veth1 (Created this for connecting a VM2 with IP 10.10.1.22 with veth1 interface ) i. sudo ip link set veth1 up j. sudo ovs-vsctl add-port veth1 h. sudo ovs-vsctl set-controller tcp:192.168.0.1:6633 (After this command the controller PC shows a switch is connected) 3. I performed the same steps in Switch PC 2 with eth0 IP 192.168.0.3/24 and br0 IP 10.10.1.3/24 and VM3 IP is 10.10.1.31.
However the issue is that I am not able to see any successful ping between VM1 to VM3 which are on different Switch PCs. However VM1 and VM2 can ping each other. The other thing I observed is there is no flow installed by the controller on the Switch PCs bridge when I tried to ping from VM1 to VM2 or VM1 to VM3. However Switch PCs are connected with the controller. Can you shed light into it. Thanks.
