Abstract
Techniques are described herein for performing filtering of frames by a provider edge device. The techniques comprise receiving information about one or more local customer edge devices in communication with a provider edge device. The techniques further comprise receiving a frame (e.g., a multi-destination frame) at the provider edge device to be provided to multiple customer edge devices. The techniques further comprise, upon determining, based on information included in the frame, that the device at which the frame originated is not a root device, identifying a subset of the set of local customer edge devices associated with a root status and providing the frame to the subset of the set of local customer edge devices while not providing the multi-destination frame to local customer edge devices outside of the subset.
