Hi again,
Sorry for bother you, but i have some doubts about my network configuration. 
A topology of my network, I send you in attachment, but it has three OVS and two \
host, the ovs are VMs.

Before I configure the ovs exist connection between the different networks, but after \
i configure the ovs, lost the conection between network and i don't know why? Can be \
something bad configured? The routing table are same before and after the \
configuration.

My version of ubuntu is 12.04, the version of openvswitch is 1.7.3 and  the version \
of floodlight is 0.85. I have followed respectives tutorial in oficial web sites to \
install, like that openvswitch and the floodlight.

My first experiencies had


My rule to OVS1:

flow1 = {
                        'switch':"00:00:fe:20:24:01:1b:4c",
                        "name":"flow-mod-1",
                        "cookie":"0",
                        "priority":"0",
                        "ingress-port":"5",
                        "active":"true",
                        "actions":"output=4"
        }

In the ovs you can see:

VM1:

root at rg1-virtual-machine:/home/rg1# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
 cookie=0xa000004039d1a6, duration=132.731s, table=0, n_packets=0, n_bytes=0, \
idle_age=132, priority=0,in_port=5 actions=output:4


My rules tou OVS2:

flow2 = {
                        'switch':"00:00:fa:8a:63:21:05:4f",
                        "name":"flow-mod-2",
                        "cookie":"0",
                        "priority":"0",
                        "ingress-port":"4",
                        "active":"true",
                        "actions":"output=2"
        }

flow4 = {
                        'switch':"00:00:fa:8a:63:21:05:4f",
                        "name":"flow-mod-4",
                        "cookie":"0",
                        "priority":"0",
                        "ingress-port":"2",
                        "active":"true",
                        "actions":"output=4"
                }

In the ovs you can see:

VM2:
root at rg1-virtual-machine:/home/rg1# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
 cookie=0xa000004039d1a7, duration=35.263s, table=0, n_packets=17, n_bytes=884, \
idle_age=2, priority=0,in_port=4 actions=output:2  cookie=0xa000004039d1a9, \
duration=35.252s, table=0, n_packets=12, n_bytes=504, idle_age=9, \
priority=0,in_port=2 actions=output:4

Is normal the flag of table are same in the two different rules?


My rule to ovs3:
flow3 = {
                        'switch':"00:00:be:53:b7:7f:52:49",
                        "name":"flow-mod-3",
                        "cookie":"0",
                        "priority":"0",
                        "ingress-port":"5",
                        "active":"true",
                        "actions":"output=3"
                }


VM3:

root at rg1-virtual-machine:/home/rg1# ovs-ofctl dump-flows br0
NXST_FLOW reply (xid=0x4):
 cookie=0xa000004039d1a8, duration=64.164s, table=0, n_packets=0, n_bytes=0, \
idle_age=64, priority=0,in_port=5 actions=output:3

My problem in this case is that when i tried ping between two host, the ovs fails my \
rule and there no propation of arp, i.e, the arp go by eth1 of VM1 and eth1 of VM3. \
Can you explain why the ovs fails my rules?

In the second case have a new two brides to exist conection between hosts, but after \
I configure the ovs, this conectivity is lost and again I don't know why :/. And my \
rules look fine in the ovs and the floodlight for that I don't know what am I doing \
wrong.  In this case there no propagation of arp by host to the openflow network.


Thanks so much.
