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.

Abstract: In an embodiment, a method includes receiving an address-resolution-protocol (ARP) request at a first edge device from a first host device, advertising a first remote route associated with a first flag indicating the first edge device operates in a layer-3 optimized integrated-routing-and-bridging (IRB) mode by the first edge device based on the ARP request, receiving the first remote route at a second edge device from the first edge device, responsive to detecting the first flag by the second edge device, installing the first remote route into a layer-2 routing information base (RIB) associated with the second edge device.

Abstract: Techniques are described herein for resolving conflicts in role statuses assigned to a customer edge device by multiple provider edge devices in communication with that customer edge device. In embodiments, such techniques may involve receiving information about a customer edge device in communication with the first provider edge device and storing, based on the information about the customer edge device, an indication of a first role status of the customer edge device. The techniques may further involve receiving, from at least one second provider edge device in communication with the customer edge device, an advertisement message that includes a second role status of the customer edge device, comparing the first role status to the second role status, and upon determining that the first role status does not match the second role status, updating the first role status of the customer edge device.
