1.8 Configuring BPDU Tunnel
1.8.1 Introduction
The BPDU Tunnel function enables BPDUs to be transparently transmitted between
geographically dispersed user networks through specified VLAN VPNs in operator’s
networks, through which spanning trees can be generated across these user networks
and are independent of those of the operator’s network.
As shown in Figure 1-6, 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 BPDU packets at the ingress to have MAC addresses in a special format, and
