   In an EVPN-IRB based network overlay, EVPN all-active multi-homing
   enables multi-homing for a CE device connected to two or more PEs via
   a LAG bundle, such that bridged and routed traffic from remote PEs
   can be equally load balanced (ECMPed) across the multi-homing PEs.
   This document defines extensions to EVPN procedures to optimally
   handle unequal access bandwidth distribution across a set of multi-
   homing PEs in order to:

     o provide greater flexibility, with respect to adding or
       removing individual PE-CE links within the access LAG

     o handle PE-CE LAG member link failures that can result in unequal
       PE-CE access bandwidth across a set of multi-homing PEs
