Hi, I am running OVS inside a VM. I have only one virtual NIC from which i can receive traffic. I was trying to do something wherein i create different GRE tunnels terminating at different VMs based on the result of some classification done on the incoming packets. You can imagine that i have packets belonging to different sessions that need to be identified and sent to a different GRE tunnel.
Given that i have only one NIC from which i can receive packets, i can only create one bridge right? I say this because its only the bridge in which i have added this virtual NIC that i will be able to receive packets. I need to do whatever classification i want inside this bridge and send packets out on different GRE tunnel ports. I will however have to be very careful in doing this since all traffic by default will be flooded to all ports of the bridge. And hence, if i am not very careful with my flow rules, then i will leak traffic from one session to the other. Is my understanding correct here? Ideally i would like to create a different bridge per session so that traffic can be isolated. Any ideas on how i can achieve this? Thanks, Abhishek
