MANAGING LINK AGGREGATION TRAFFIC IN EDGE NODES
First Claim
1. A computer-implemented method comprising:
- configuring, by a first network edge device, a mapping between a physical network interface of the first network edge device and a plurality of logical interfaces within the first network edge device, wherein a second network edge device also configures a mapping between a physical network interface of the second network edge device and a copy of the plurality of logical interfaces within the second network edge device, and wherein each of the logical interfaces is assigned a corresponding set of first and second layer networking addresses that is replicated across the first and second network edge devices;
receiving, by the first network edge device via the physical network interface of the first network edge device, a first address resolution request including a source and a destination, the destination being a first layer networking address assigned to one of the plurality of logical interfaces;
determining, by the first network edge device from a mapping of first layer networking addresses of the logical interfaces to second layer networking addresses of the logical interfaces, a second layer networking address assigned to the destination logical interface; and
transmitting, by the first network edge device via the physical network interface of the first network edge device to the source of the address resolution request, a first address resolution response including the determined second layer networking address assigned to the destination logical interface.

Abstract
Exemplary methods, apparatuses, and systems include a first network edge device configuring a mapping between a physical network interface and a plurality of logical interfaces. A second network edge device also configures a mapping between a physical network interface and a copy of the plurality of logical interfaces. Each of the logical interfaces is assigned a corresponding set of first and second layer networking addresses that is replicated across the first and second network edge devices. The first network edge device receives a first address resolution request via the physical network interface of the first network edge device that includes a source and a destination. The destination is an address assigned to one of the plurality of logical interfaces. The first network edge device determines a second layer networking address assigned to the destination logical interface and transmits an address resolution response including the determined second layer networking address.
