Abstract
A method is implemented by a network device functioning as a provider edge (PE) device to determine a designated forwarder (DF) for sending broadcast, unknown unicast or multicast (BUM) traffic to a customer edge (CE) device, which is connected to a plurality of PE devices in an Ethernet virtual private network (EVPN) instance on a given Ethernet segment. The method reduces a time for DF determination and loss of traffic for the CE device. The method determines whether a number of active links from the network device to the CE device is greater than an active link minimum. The method also determines that the network device is the DF in response to determining that the number of active links is greater than the active link minimum.
