Abstract
A controlling device is disclosed for Ethernet virtual private network (EVPN). According to an embodiment, the controlling device determines a first provider (P) device which is to handle broadcast, unknown unicast or multicast (BUM) traffic from a first provider edge (PE) device in an EVPN instance, on behalf of remaining PE devices in the same EVPN instance. The controlling device performs route reflection from the remaining PE devices to the first PE device such that the first PE device knows that BUM traffic needs to be forwarded to the first P device. The controlling device configures the first P device such that upon receipt of BUM traffic from the first PE device, the first P device can forward the BUM traffic to the remaining PE devices.
