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 receive, from a provider edge device, a packet to be provided to one or more other provider edge devices. Some of the one or more other provider edge devices may be multi-homed with a same customer edge device as the provider edge device. The device may configure a source IP address of the packet based on a capability of an assisted replicator device after receiving the packet. The capability may relate to whether the assisted replicator device is capable of retaining the source IP address of the packet as received from the provider edge device. The device may provide the packet to at least some provider edge devices, of the one or more other provider edge devices, after configuring the source IP address of the packet.

Abstract: A device may receive, via a first message, first route information for directing network traffic for a network. The first route information may identify a media access control (MAC) route corresponding to a MAC address associated with a host device connecting to a subnet of the network. The first route information may fail to include Internet protocol (IP)/MAC binding information associated with the host device. The device may transmit a request for IP/MAC binding information associated with the host device. The device may receive a response, to the request for IP/MAC binding information, identifying the IP/MAC binding information. The device may advertise, via a second message, second route information for directing network traffic for the network based on receiving the response identifying the LP/MAC binding information. The second route information may identify the IP/MAC binding information associated with the host device.

Abstract: A network device may originate a route, and may designate the route as a first colored route having a first color. The network device may advertise the first colored route to a first intermediate network device to cause the first intermediate network device to propagate the first colored route to an ingress network device over a first colored border gateway protocol session. The network device may designate the route as a second colored route having a second color, and may advertise the second colored route to a second intermediate network device to cause the second intermediate network device to propagate the second colored route to the ingress network device over a second colored border gateway protocol session.

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 generate a route advertisement that includes a media access control (MAC) address. The MAC address may correspond to a data link established between the network device and a customer edge (CE) device. The network device and the CE device may be associated with an Ethernet virtual private network (EVPN) that includes other network devices that are remote from the CE device. The network device may cause the route advertisement to be outputted over the EVPN. The route advertisement may permit the other network devices to learn that the data link is directly reachable via the MAC address, and may permit the other network devices, when configured as maintenance endpoints (MEPs), to directly address performance monitoring-related unicast packets, intended for the data link, using the MAC address, such that flooding of the performance monitoring-related unicast packets is avoided.

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.
