[ovs-discuss] Failed to add group action

2017-10-15 Thread Yuanjun Yao
Hi all, I have a network with topology h1--s1==s2--h2. Where "==" means there are two links between s1 and s2. I want to use group action for multi-path routing between h1 and h2. I experimented on a physical network, where s1 and s2 are Ubuntu16.04 with Openvswitch 2.5.2. (1) In s1, I added "eth1

[ovs-discuss] How to notify the SDN controller when adding a new interface to OVS bridge?

2017-04-07 Thread Yuanjun Yao
Hi All, I want to dynamically add new interface to OVS bridge, but it seems that the SDN controller knows the interfaces and mac addresses only when we first set controller for the bridge. When I add a new interface to the bridge, the SDN controller doesn't know the existence of the new interface.

[ovs-discuss] OVS bridge absorbing ARP replies

2016-12-29 Thread Yuanjun Yao
Hi all, My network topology is host1(eth1:192.168.1.2)—(eth2:192.168.1.1)host2. I added an OVS bridge on host2 and added eth2 as a port. I configured the ip address via SDN controller. I could ping from host 1 to host2, but failed the other way. My configuration commands on host2 are: #ovs-vsctl
