Abstract: The techniques describe example network systems for adaptively determining whether to perform ingress replication or assisted replication of a multicast flow based on classification of the multicast flow. For example, a provider edge (PE) device of a plurality of PE devices participating in an EVPN comprises one or more processors operably coupled to a memory, wherein the one or more processors are configured to: receive a multicast traffic flow, determine a classification of the multicast traffic flow, and perform, based at least in part on the classification of the multicast traffic flow, one of: ingress replication of the multicast traffic flow or assisted replication of the multicast traffic flow.

Abstract: In some examples, a method includes receiving, by an egress network device for a network, messages from each of a plurality of ingress network devices for the network, wherein each of the messages specifies a multicast source, a multicast group, and an upstream multicast hop weight value for multicast traffic for the multicast source and the multicast group; selecting, by the egress network device and based on the upstream multicast hop weight values specified by the received messages, one of the plurality of ingress network devices to which to send a multicast join message of a plurality of multicast join messages for the multicast source and multicast group; and sending, by the egress network device, the multicast join message to the selected one of the plurality of ingress network devices.

Abstract: In general, techniques are described for providing Hot-Root Standby in Global Table Multicast (GTM) environments. For example, in such GTM environments, normally a single unicast route to the customer multicast source (“C-Source”) will be available to egress provider edge (PE) routers. As described herein, ingress PE routers may advertise multiple routes to a C-Source, including unicast routes that include Route Import Extended Communities, which are imported by egress PE routers. This enables an egress PE router to have multiple paths to the C-Source, and the egress PE router may generate multiple C-multicast source tree joins for respective ingress PE routers in order to receive respective multicast streams sourced by the C-Source from the ingress PE routers.

Abstract: An example egress network device includes at least one computer processor and a memory. The memory includes instructions that cause the at least one computer processor to receive messages from each of a plurality of ingress network devices. Each message specifies a multicast source as an anycast address that belongs to two or more sources, a multicast group, and a customer site identifier that uniquely identifies a customer network device via which the anycast address is reachable. The instructions cause the at least one computer processor to select, based on the customer site identifiers, one of the plurality of ingress network devices to which to send a multicast join message of a plurality of multicast join messages for the multicast source and multicast group. The instructions cause the at least one computer processor to send the multicast join message to the selected one of the plurality of ingress network devices.

Abstract: The techniques describe example network systems providing core-facing designated forwarder (DF) election to forward multicast traffic into an EVPN of a core network. For example, a first PE device of a plurality of PE devices participating in an EVPN comprises one or more processors operably coupled to a memory, wherein the one or more processors are configured to: determine that a first multicast traffic flow has started for the first PE device; in response, send a source-active (SA) route to indicate the first multicast traffic flow has started for the first PE device; receive, from a second PE device, a second SA route that indicates that a second multicast traffic flow has started for the second PE device; and perform an election of a core-facing DF from among the first PE device and second PE device, wherein the core-facing DF is configured to forward the multicast traffic into the EVPN.
