Abstract: In some examples, a customer edge device (CE) is configured to receive configuration data for multi-homed connectivity for a local layer 2 (L2) network with a L2 virtual private network (L2VPN) for a layer 3 (L3) network for switching L2 packet data units (PDUs) among two or more L2 networks connected to the L3 network including the local L2 network, wherein the configuration data for multi-homed connectivity configures the CE with a primary attachment circuit to a primary neighbor provider edge device (PE) for the L2VPN and with a backup attachment circuit to a backup neighbor PE for the L2VPN; and generate and send, in response to snooping a multicast join message indicating a multicast group, a control plane message via the backup attachment circuit to the backup neighbor PE for the L2VPN, wherein the control plane message is destined for the backup neighbor PE for the L2VPN.

Abstract: A device may receive a plurality of traffic flows to be provided to a set of destination devices. The device may process the plurality of traffic flows to identify respective sets of attributes associated with the plurality of traffic flows. The device may assign one of a plurality of traffic forwarding techniques, to a first traffic flow, of the plurality of traffic flows, based on the respective sets of attributes associated with the plurality of traffic flows. The device may provide the plurality of traffic flows to the set of destination devices. The device may determine that a condition, of a set of conditions associated with the plurality of traffic flows, has been satisfied in association with providing the plurality of traffic flows to the set of destination devices. The device may perform a set of actions after determining that the condition has been satisfied.
