    Abstract: In some embodiments, an apparatus includes a core network node configured to associate with a native multicast group a first client device that is associated with a first virtual local area network (VLAN) and operatively coupled to the core network node via a first access network node and an aggregation network node. The core network node can associate with the native multicast group a second client device that is associated with a second VLAN and operatively coupled to the core network node via a second access network node and the aggregation network node. The core network node can define a multicast VLAN including the first VLAN and the second VLAN based on the native multicast group. The core network node can receive a multicast data unit associated with the native multicast group and can also define a single instance of the multicast data unit for the multicast VLAN.

    Abstract: In some examples, a method includes selecting, by a first virtual routing node of a single-chassis network device having a plurality of forwarding components and a plurality of fabric links coupling respective pairs of the plurality of forwarding components at respective fabric interfaces of the plurality of forwarding components, a fabric interface of a forwarding component of the plurality of forwarding components that has an egress interface toward a network destination and that is associated with the first virtual routing node; in response to receiving a message specifying the fabric interface, storing, by the second virtual routing node to a context forwarding table of the second virtual node, the fabric interface as a next hop for the network destination; selecting, by the second virtual routing node and based on the context forwarding table and a context next hop in a first forwarding table pointing to the context forwarding table, the fabric interface for forwarding network packets destined for the network destination.

    Abstract: An apparatus may (1) receive, at the service provider's network, at least one flow of network traffic from a remote device included in a user's private network, (2) identify, within the flow of network traffic, at least one potentially non-unique private address that represents the remote device with respect to the user's private network, (3) determine, at least one unique routable address that represents the remote device with respect to the service provider's network based at least in part on a network interface assigned to the user's private network, the potentially non-unique private address, and the address-translation table, and then (4) translate, in response to determining the unique routable address, the potentially non-unique private address to the unique routable address to facilitate routing return network traffic to the remote device in connection with the flow of network traffic. Various other apparatuses, systems, and methods are also disclosed.
