14.2.1. Data-Plane Learning

Consider that the PEs perform data-plane learning for local MAC addresses learned from local CEs. This enables the PE(s) to learn a particular MAC address and associate it with one or more interfaces, if the technology between the PE and the CE supports multipathing. The PEs can now load balance traffic destined to that MAC address on the multiple interfaces.

Whether the CE can load balance traffic that it generates on the multiple interfaces is dependent on the CE implementation.
