Abstract: Port synchronization is provided for multicast on an Ethernet segment (ES) in which a device (CE) is multihomed to at least two devices (PE1 and PE2) of a VLAN. Such example embodiments may do so by providing computer-implemented method for use in a first device belonging to an Ethernet virtual private network (EVPN) and an Ethernet segment (ES), the ES including a second device and a third device, the second device also belonging to the EVPN, the third device being multihomed to the first device and the second device via the ES, and the first and second devices having snooping enabled for multicast group messages, the computer-implemented method comprising: (a) detecting, on a first interface of the first device, from the third device via the ES, a multicast query message, wherein the multicast query message is not detected by the second device via the ES; (b) marking the first interface of the first device as a multicast router port; (c) generating a message identifying the ES and including information encoding that the multicast query message was detected on the ES; and (d) sending, via the EVPN, the message generated to the second device so that the second device will mark an interface, on the ES, with the third device, as a multicast router port.

Abstract: A device may store first information regarding a first pseudowire connection with a first device, wherein the first pseudowire connection provides access to an Ethernet virtual private network (EVPN) to communicate with a host device. The device may store second information regarding a second pseudowire connection with a second device, wherein the second pseudowire connection provides access to the EVPN to communicate with the host device. The device may receive a message that includes a configuration identifier and identify the configuration identifier. The device may change a first characteristic of the first pseudowire connection based on the configuration identifier. The device may change a second characteristic of the second pseudowire connection based on the configuration identifier. The device may receive data from the host device based on changing the first characteristic of the first pseudowire connection and changing the second characteristic of the second pseudowire connection.

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.
