Abstract: A method and network device to execute an Ethernet Virtual Private Network (EVPN) protocol to configure the network device to participate as one of a plurality of customer edge (CE) routers that provide an active-active configuration for an Ethernet segment coupling the CE routers to a plurality of provider edge (PE) routers, wherein the processor is configured to determine whether a packet that is to be forwarded is an operations, administration, and management (OAM) packet; in response to determining that the packet comprises an OAM packet, replicate the OAM packet for one or more interface links of an Ethernet segment associated with the CE router; configure forwarding instructions to the one or more interface links of the Ethernet segment associated with the CE router; and forward the OAM packet and the replicated OAM packets to the PE routers.

Abstract: In one example, a method includes performing L2 learning of a C-MAC address included in a first L2 data message by a first provider edge (PE) router included in an Ethernet Segment of a Provider-Backbone Bridging Ethernet Virtual Private Network (PBB-EVPN); sending to a second PE router within the Ethernet Segment an L2 control message comprising the C-MAC address and a B-MAC address corresponding to the Ethernet Segment of the PBB-EVPN, wherein the L2 control message informs the second PE router of the reachability of the C-MAC address through the first PE router; receiving, by the first PE router and from the second PE router, a second L2 data message as unicast traffic destined for the C-MAC address; and forwarding the second L2 data message to the first CE router.

Abstract: Techniques are described for utilizing Protocol Independent Multicast Sparse Mode (PIM-SM) to transport BUM (broadcast, unknown unicast, and multicast) traffic in a Virtual Extensible LAN (VXLAN) underlay of a data center, where the BUM traffic is received on active-active, multi-homed Ethernet virtual private network (EVPN) interconnects between multiple physical data centers. For example, the techniques may readily be applied to support usage of PIM-SM where provider edge (PE) routers of the EVPN operate as gateways between the EVPN and the VXLAN spanning the data center interconnect.
