to EX Series switches that are not part of the local broadcast domain.
Figure 34 on page 1370 shows a customer network that includes two sites that are connected
across a service provider network. Site 1 contains three switches connected in a Layer 2
network, with Switch A designated as a provider edge (PE) device in the service provider
network. Site 2 contains a Layer 2 network with a similar topology to that of Site 1, with
Switch D designated as a PE device.
