    Abstract: Managing prefix lists at edge devices can include detecting, at an edge device, a traffic flow that can include a packet that specifies a destination address. The edge device can measure a bandwidth associated with the traffic flow, identify a flow bandwidth threshold defined for the edge device, and determine if the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold. If a determination is made that the bandwidth associated with the traffic flow satisfies the flow bandwidth threshold, the edge device can include the destination address in a prefix list stored at the edge device. If a determination is made that the bandwidth associated with the traffic flow does not satisfy the flow bandwidth threshold, the edge device can omit the destination address from the prefix list stored at the edge device.

    Abstract: A system for indirect border gateway routing may include a provider edge router, virtual routing and forwarding instance, a point identification list, and a virtual routing and forwarding import instance. The virtual routing and forwarding import instance may be adapted to receive a route from the provider edge router, in which the route may include a pointer identification directing the virtual routing and forwarding import instance to scan the pointer identification list for the route target associated with multiple virtual routing and forwarding instances. The virtual routing and forwarding import instance may be adapted to import the route to at least one virtual routing and forwarding instance having a route target on the pointer identification list.

    Abstract: A recovery route reflector with a monitoring module and a BGP state establishment module is peered with a plurality of primary route reflectors. Each of the plurality of primary route reflectors is peered with a set of provider edge devices. The BGP state between the recovery route reflector and the plurality of primary route reflectors is periodically monitored. When a primary route reflector fails the BGP state between the recovery route reflector and the failed primary route reflectors is idle, and the recovery route reflector establishes a peer session with the provider edge devices that had been peered with the failed route reflector.
