Abstract
Techniques are described to provide split-horizon packet forwarding so as to ensure that packets from the customer network that are injected into the provider backbone bridging Ethernet Virtual Private Network (PBB-EVPN) by one of the provider edge (PE) devices of the multi-homed Ethernet segment are not forwarded back toward the customer network by a different PE device connected to the same multi-homed Ethernet segment. For example, a method may comprise receiving a packet via a core-facing interface of a first PE device, determining the Ethernet segment associated with the PE devices by a lookup operation based on keys of the packet; in response to determining the Ethernet segment, supplanting the core-facing interface of the first PE device with a virtual interface associated with the keys, and forwarding the packet to a second CE device without forwarding the received packet back to the Ethernet segment associated with the first PE device.
