Abstract
A provider edge (PE) device may receive an indication to perform a designated forwarder (DF) election associated with a network segment that includes the PE device, one or more other PE devices, and a client edge (CE) device. The PE device, the one or more other PE devices, and the CE device may be associated with an Ethernet virtual private network (EVPN) that includes a group of EVPN instances (EVIs). The PE device may perform the DF election in order to determine election information associated with the PE device. The election information may include information associated with a particular EVI, of the group of EVIs, for which the PE device is to act as a DF. The PE device may provide the election information to the CE device to cause the CE device to provide traffic, associated with a particular VLAN included in the particular EVI, to the PE device.
