This argument must be a multicast MAC address.DescriptionUse the bpdu-tunnel tunnel-dmac command to configure the destination MACaddress for protocol packets transmitted along a BPDU tunnel.Use the undo bpdu-tunnel tunnel-dmac command to restore the default destinationMAC address.By default, the destination MAC address for protocol packets transmitted along a BPDUtunnel is 010f-e200-0003.Caution:z To prevent the devices in the service provider network from processing the tunnelpackets as other protocol packets, the MAC address for tunnel packets must be amulticast address specially for BPDU tunnels in the service provider network.z The destination MAC addresses configured at the two ends of a BPDU tunnel mustbe the same; otherwise, the protocol packets cannot be transmitted and forwardednormally.Related commands: display bpdu-tunnel.
