To prevent a backbone network edge device from sending the received Layer 2 protocol data units (PDUs) to its CPU for processing and ensure that the Layer 2 PDUs are tunneled across the backbone network, configure the edge device to replace the multicast destination MAC address in Layer 2 PDUs with a specified multicast MAC address.
The system view is displayed.
An edge device is configured to replace the multicast destination MAC address in Layer 2 PDUs with a specified multicast MAC address. This specified multicast MAC address is also called a group MAC address.
The configuration is committed.
