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.
