, the service provider network comprises packet input and
output devices. The customer networks include network A and network B. Through the
configuration on the devices at both ends of the service provider network, the
destination MAC address of the BPDU packet is replaced with a MAC address in a
special format at one end, and the MAC address is converted back to the original
destination MAC address at the other end. In this way the packet is transmitted
transparently over the service provider network.
