[ovs-discuss] how to configure openvswitch connected to a host
Hello, I want to configure the following topology so that host1 can ping host2. host1openvswitch1-openvswitch2---host2 host1(10.0.1.10/24) - (10.0.1.20/24) openvswitch1(10.0.0.1/16) -- --- (10.0.0.2/16) openvswitch2(10.0.2.20/24) (10.0.2.10/24) host2 I want to configure openvswitches and bridges. But I do not know how to configure openvswitches to forward packets toward hosts. Do you have any suggestion? Thank you in advance ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] OVS doesn't apply action in packet_out message
I have some OVSs connected to ONOS controller. OVS1---OVS2OVS3 when OVS1 wants to send packets to OVS3, OVS2 sends packet_in messages to the controller including ARP message and ONOS sends packet_out messages contain OFPP_FLOOD as an action. However, OVS2 doesn't flood the flow toward the OVS3. Is there any way to find out why OVS2 by receiving the packet_out, doesn't apply the action on the flow? Thanks, ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] OVS with one interface
Hello, I have three openvswitch as follows, ovs1 --- ovs2---ovs3 Each ovs only has *one interface* to communicate with other ovs. I want to add some flow rules to ovs2, to forward ip and arp packets form ovs1 to ovs3 when I run "ip address_ovs1 ping ip address_ovs3". I tried different flows, but they don not work. for example: ovs-ofctl add-flows br2 "table=0, arp, nw_dst=10.0.0.3, actions=goto_table:1" ovs-ofctl add-flows br2 "table=1, actions=nw_dst=10.0.0.3, in_port(or normal)" Do you have any suggestion? ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] Connecting pox controller to openvswitch
Hello, I run pox controller in the home route of ubuntu 14.0 and I want to connect an OVS simulated in the CORE emulator to this controller . I checked different ip addresses of pox controller as follows, ovs-vsctl set-controller mybridge tcp:127.0.0.1:6633 ovs-vsctl set-controller mybridge tcp:127.0.0.1:6653 ovs-vsctl set-controller mybridge tcp:127.0.0.1:6633 ovs-vsctl set-controller mybridge tcp:0.0.0.0:6633 ovs-vsctl set-controller mybridge tcp::6633 However, OVS cannot connect to the controller. Also, using "ifconfig -a", I have two different addresses for eth0 and eth1 of the ubuntu. Should you I use this ip addresses for the connection to the controller? (these ip addresses are not in the same network of defined ip address of OVS.) Thank you ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] openvswitch and pox controller in wireless network
Hello, I have a network with four wireless nodes as below, All wireless nodes are running openvswitch and one of them also run pox controller (n1). n1 is in range of all nodes. n2 only is in range of n3 (and n1) and n4 is in range of n3 (and n1). When I check wireshark, I can see the openflow messages between the other three nodes and pox controller. n1 n2 n3 n4 However, for example, when n2 pings n3, I can see each time (per each ICMP packet) a packet_in message will be sent to the controller and when I check the flow table of n2 the action is normal. In this case, I have some questions: even if the wireless nodes are in the transmission range of each other, does the nodes have to send packet_in message to the controller in case of pining? Also, I can see the LLDP messages, however, n4 cannot ping n2. In the packet_out message, I can see the action is sending the packet to the wireless interface of n4. But n3 doesn't forward this packet to n2. Do you have any suggestion? Thank you ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] Connection OVS to pox controller
Hello, I am planning to connect three openvswitch nodes to the pox controller in ns3. So I connected these three nodes directly to the controller (wired links). In this case, each interface has one IP address so the controller has three different addresses and also I think pox should listen to three different ports to get the packets form switches and vice versa. Do you have any suggestion that how I can connect openvswitch nodes to the pox controller?

Re: [ovs-discuss] Wireless OVS
In MANET (mobile ad hoc networks), wireless nodes can communicate together without any access points. Should I still consider hostapd for each wireless node in my simulation? I only run OVS on each node; however, it seems that I have to configure something to allow nodes to know about the mac address of each other On Mon, Sep 11, 2017 at 12:58 PM, Raymond Burkholder wrote: > > > I am working with CORE Network Emulator and I implemented a MANET > including three wireless nodes. > > I am not familiar with MANET, but if this is hostapd based? > > > > > I am trying to run OVS on these three nodes.

[ovs-discuss] Wireless OVS
Hello, I am working with CORE Network Emulator and I implemented a MANET including three wireless nodes. I am trying to run OVS on these three nodes. The topology is as follows, node (1) --- node(2) -- -node(3) In this topology, for the first step, when I run OVS on wireless nodes as a normal switch (standalone), node(1) can ping node(2), and node(2) can ping node(3). However, node(1) cannot ping node(3). When I captured the packets, there is no ARP Reply packet to help node (1) to know the mac address of node(3). (I did not have this problem when I run OVS on the same topology in wired networks.) Could you help me with this issue? Could you let me know how to configure OVSs to activate ARP Reply packets and how to see the mac table ?
