Abstract: A device may receive, from a first device associated with a first LAN, network traffic destined for a second LAN. The device may provide the first LAN with access to a core network. The device may not provide the second LAN with access to the core network. The device may identify, based on the network traffic, a Layer 3 address associated with a second device. The second device may be associated with the second LAN. The device may determine that the first device is categorized as a leaf device within an Ethernet Tree provided by the device. The device may determine, based on the Layer 3 address, that the second device is categorized as a leaf device within the Ethernet Tree. The device may drop the network traffic based on determining that the first device and the second device are categorized as leaf devices within the Ethernet Tree.

Abstract: A first device may receive network traffic including a first label. The first label may be an inclusive multicast label associated with a second device. The second device may be a designated forwarder for an Ethernet segment. The first device may determine a second label based on receiving the network traffic including the first label. The second label may be used to route the network traffic to a customer edge device, via a third device, rather than the second device. The third device may be a non-designated forwarder for the Ethernet segment. The first device may provide the network traffic, including the second label, to the third device to permit the third device to provide, via the Ethernet segment, the network traffic to the customer edge device based on the second label when a failure occurs in association with the second device.
