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.
