Abstract
Techniques for load balancing network traffic over virtual point-to-point data links at a data-link layer include determining a particular group of virtual point-to-point data links that reach a particular local area network of one or more network nodes. A particular data-link address for a particular node of the particular local area network is associated with each virtual point-to-point data link of the particular group. When a data packet is received that includes data that indicates the particular data-link address as a destination; one virtual point-to-point data link of the group is determined to balance traffic among the group. The data packet is sent only over the one virtual point-to-point data link. These techniques enable virtual point-to-point data links through two or more intermediate network nodes, such as a pair of provider edge nodes, to be bundled for load balancing purposes.
