Enable the service provider network to transmit STP packets of the customer network through
BPDU tunnel. The destination MAC address for tunnel packets is 010f-e233-8b22.
Enable the VLAN-VPN feature for the service provider network, and enable the service provider
network to use VLAN 100 to transmit data packets of the customer network.
