WebAliasing is the process of letting one network device perform a task that would ordinarily be the responsibility of another. Aliasing is the way that EVPNs provide load-balancing to CEs that are in all-active mode, even when the MAC address is learned by only one of the multiple PEs. The PEs advertise the ESI in MAC routes for all-active mode.
