1. Ovs support to create multiple bridge, what is excuse me this kind of situation general application scenario?
2. How to communicate between multiple bridge? , for example, I created two bridge br0 joined the port p01, joined the ports in br1 p02
In traditional networks, is between the two bridge connection, so if is the communication between the same vlan, so just a flood; If is the communication between different vlans, then through the layer 3 routing can also communication
But on the ovs, although belonging to two bridge, but in the kernel, these ports actually belong to the same physical machine, if belong to the same namespace, between them that is equivalent to the kernel internal port communication, neither need routing, also do not need to exchange
If belong to different namespace, so at this time and how to communicate?
