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: In some implementations, a first network device that hosts a bridge domain (BD) may receive inter-subnet multicast traffic associated with the BD. The BD may forward, using a supplemental bridge domain (SBD) interface of the first network device, and via an SBD, a first copy of the inter-subnet multicast traffic to a second network device that hosts the BD. The first network device may forward, using the SBD interface and via the SBD, a second copy of the inter-subnet multicast traffic to a third network device that does not host the BD. The first network device may forward, using an integrated routing and bridging (IRB) interface of the first network device associated with the BD, a third copy of the inter-subnet multicast traffic to a fourth network device that hosts the BD (e.g., when the fourth network device is a multihoming peer of the first network device).

Abstract: A network device may receive a first redundant multicast flow indication from a first network device, and may receive a second redundant multicast flow indication from a second network device. The device may designate a primary multicast flow based on the first redundant multicast flow indication, and may designate a backup multicast flow based on the second redundant multicast flow indication. The device may accept the primary multicast flow and may discard the backup multicast flow.

Abstract: A controller device receives, from a plurality of assisted replication network devices, respective utilization information associated with the plurality of assisted replication network devices. The controller device generates, based on the respective utilization information associated with the plurality of assisted replication network devices, load balancing information for a network device associated with two or more assisted replication network devices of the plurality of assisted replication network devices, and sends, to the network device, the load balancing information. The network selects, based on the load balancing information, a particular assisted replication network device of the two or more assisted replication network devices. The network device receives a traffic flow that is to be multicast and sends the traffic flow to the particular assisted replication network device, wherein sending the traffic flow to the particular assisted replication network device permits the particular assisted replication network device to multicast the traffic flow.

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.
