Hello, I am trying to figure out the proper method to route between two subnets and can not seem to figure it out.
I have a setup like: H1 —> OVS —> H2 where each host is running in its own VM with IPs: H1 = 192.168.0.1 OVS = 192.168.0.13 (eth0) and 10.0.0.1 (eth1) H3 = 10.0.01 I would like to have OVS flows that would allow H1 to see H3 (and H3 see H1). I first tried to use IP forwarding and Linux routing to solve the problem, but I could not figure out how to setup the routing tables on either H1 or H3, since adding two ports to the bridge would eliminate one of the IPs on OVS. I could get routing to work fine for the remote host that was on the same network as the bridge, but had issues with the other IP. I discovered this tutorial: https://www.youtube.com/watch?v=TD5wmoD7XOE&list=UUEoaojfEY_6L5TWWjIn9t9Q <https://www.youtube.com/watch?v=TD5wmoD7XOE&list=UUEoaojfEY_6L5TWWjIn9t9Q> that used flows to handle some simple routing. While the flows described in this video would work, the route issue still exists, preventing H1 from ARPing a gateway to get a MAC address for H3. What is the proper way to have two NICs, each on a different subnet attached to a single OVS, and then have external hosts route correctly to the switch? Thanks for any suggestions. Brian
