Bridges

Bridges are MidoNet’s L2 forwarding elements.

You can create virtual ports on bridges. In turn, you can attach VMs to virtual ports on a bridge. All VMs attached to the same bridge are reachable through L2 connectivity. You can connect ports on virtual bridges to another virtual device or a physical machine.

Bridges store the mappings between MAC addresses of network devices that send received frames and the bridge ports they receive them from.

The bridge dynamically builds a table of the source MAC addresses and the bridge ports. The bridge uses this table to send frames destined for the network device to the correct bridge port. You can clear the MAC table.
