Understand how provider network traffic reaches the physical network through bridge mappings. The following concepts apply:

Traffic leaves the provider network and arrives at the br-int bridge.
A patch port between br-int and br-ex then allows the traffic to traverse to and from the provider network and the edge network.
Kubernetes pods are connected to the br-int bridge through a virtual ethernet pair. One end of the virtual ethernet pair is attached to the pod namespace, and the other end is attached to the br-int bridge.
