As shown in Figure 1-9, the upper part is the operator’s network, and the lower part is
the user’s network. The operator’s network comprises packet ingress/egress devices,
and the user’s network has networks A and B. On the operator’s network, configure the
arriving STP packets at the ingress to have MAC addresses in a special format, and
reconvert them back to their original formats at the egress. This is how transparent
transmission is implemented over the operator’s network.
