Abstract: The disclosed apparatus may include (1) a database that maintains a pruned multicast distribution tree and (2) a processing unit having access to the database, wherein the processing unit (A) receives at least one type 3 Ethernet Segment Identifier (ESI) message from at least one other bridge domain on at least one other computing device, (B) determines, based at least in part on the type 3 ESI message, whether the other bridge domain on the other computing device has a root access concentrator, and then (C) populates, in response to determining whether the other bridge domain has a root access concentrator, the pruned multicast distribution tree to account for the other bridge domain such that the bridge domain on the computing device is able to determine whether to send multicast traffic to the other bridge domain. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A provider edge device, capable of accessing a first type of memory and a second type of memory, may determine a network address associated with a customer edge device. The provider edge device may determine whether the customer edge device is categorized as a leaf device in an Ethernet Tree service provided by the provider edge device. The provider edge device may selectively store the network address in the first type of memory or the second type of memory based on determining whether the customer edge device is categorized as a leaf device in the Ethernet Tree service.
