Bridging: Disabling local switching in bridge domains

In a bridge domain, when a frame is received from a customer edge (CE) interface, it is flooded to the other CE interfaces and all of the provider edge (PE) interfaces if the destination MAC address is not learned or if the frame is either broadcast or multicast. To prevent CE devices from communicating directly include the no-local-switching statement at the [edit bridge-domains bridge-domain-name] hierarchy level. Configure the logical interfaces in the bridge domain as core-facing (PE interfaces) by including the core-facing statement at the [edit interfaces interface-name unit logical-unit-number family family] hierarchy level to specify that the VLAN is physically connected to a core-facing ISP router and ensure that the network does not improperly treat the interface as a client interface. When local switching is disabled, traffic from one CE interface is not forwarded to another CE interface.
