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.

Abstract: A device may store first information regarding a first pseudowire connection with a first device, wherein the first pseudowire connection provides access to an Ethernet virtual private network (EVPN) to communicate with a host device. The device may store second information regarding a second pseudowire connection with a second device, wherein the second pseudowire connection provides access to the EVPN to communicate with the host device. The device may receive a message that includes a configuration identifier and identify the configuration identifier. The device may change a first characteristic of the first pseudowire connection based on the configuration identifier. The device may change a second characteristic of the second pseudowire connection based on the configuration identifier. The device may receive data from the host device based on changing the first characteristic of the first pseudowire connection and changing the second characteristic of the second pseudowire connection.
