Abstract
In general, techniques are described for forwarding L2 BUM traffic within an Ethernet Virtual Private Network (EVPN) by implementing a forwarding preference for local interfaces of a PE device for broadcast domains in the EVPN. For example, a method includes receiving, by a first provider edge (PE) device of a plurality of PE devices configured with an EVPN instance comprising one or more broadcast domains reachable by a plurality of Ethernet segments connecting the plurality of PE devices to a plurality of customer edge (CE) devices, first EVPN routes; and configuring, by the first PE device in response to determining the first EVPN routes indicate the first PE device has a local interface for each of the plurality of Ethernet segments, forwarding information of the first PE device to cause the first PE device to perform local-bias forwarding of layer 2 (L2) packets for the EVPN instance.
