hello, I'm recently trying to create a network topology for sdn experiment as below:

network1(192.164.0.0/24): t1-h1-s1

network2(192.166.0.0/24): h2-s1

network3(192.165.0.0/24): all instances

I want to connect h1 to h2 through s1, which is installed open vswich(2.7.0) I've tried the way I used in physical network to create an OVS bridge on s1. But that dosen't work. here is what I've done on s1:

ifconfig eth1 192.166.0.4/24
ifconfig eth2 192.164.0.4/24
ovs-vsctl add-br ovs-br
ovs-vsctl add-port ovs-br eth1
ovs-vsctl add-port ovs-br eth2
ifconfig ovs-br 192.164.0.241/24
ovs-vsctl set-fail-mode ovs-br standalone

The weird thing is after I set up the bridge, the connectivity not only between h1 and h2 but also between t1 and h1 both failed. What step did I possibly go wrong? Thank you for helping.

p.s. I'm not able to modify the configuration on network node, so I don't think I could use the neutron plugins.
