Hi all,
The last weeks I been having this problem and I don't know how to fix it. I
been trying to emulate an openflow switch in a PC with Ubuntu 12.04, this pc
has three NIC with this configuration: eth0
Link encap:Ethernet direcciónHW

First I did this: ./utilities/ovs-vsctl add-br br0./utilities/ovs-vsctl
add-port br0 eth1 -- set interface eth1 type=system./utilities/ovs-vsctl
add-port br0 eth2 -- set interface eth2 type=system./utilities/ovs-vsctl
set-controller br0 tcp:192.168.0.100:6633
ovs-vsctl
show
d9a1d7af-d62a-4a9a-a56b-3739dacea4f9
Bridge "br0"
Controller
"tcp:192.168.0.100:6633"
Port "eth2"
Interface "eth2"
type: system
Port "br0"
Interface "br0"
type: internal
Port "eth1"
Interface "eth1"
type: system
And on the pox controller I got this response when I ping between hosts:
./pox.py

Non connection between the hosts (each host is connected to the switch by a
NIC):host 1 ---> eth1host 2 ---> eth2
Then I made some changes: ./utilities/ovs-vsctl add-br br0./utilities/ovs-vsctl
add-port br0 eth0./utilities/ovs-vsctl add-port br0 eth1 -- set interface eth1
type=system./utilities/ovs-vsctl add-port br0 eth2 -- set interface eth2
type=system./utilities/ovs-vsctl set-controller br0 tcp:192.168.0.100:6633

Interface "br0"
type: internal
Port "eth1"
Interface "eth1"
type: system
Port "eth0"
Interface "eth0"
Port "eth2"

type: system
And change the ip between the br0 and the eth0 (which is the one connected to
the controller):ifconfig eth0 0; ifconfig br0 192.168.0.1
netmask 255.255.255.0
And got this on the controller: ./pox.py

The only thing I want to achive is communication between the hosts and I
haven't succeed.
I alreday debug and the problem is in the ovs, I know is the configuration but
I don't know what I could do to make it right?
Hope someone help me.Thank you
