When large-block spatially continuous MAC addresses exist under a single VTEP, a large number of EVPN NLRI broadcasts can be formed; on the other hand, other VTEPs located in the same BD (Bridge Domain) also need to store a large number of VTEP/MAC mapping tables, which puts a great strain on the device.
