Chapter 2 BPDU Tunnel Configuration
2.1 BPDU Tunnel Overview
Bridge protocol data unit (BPDU) Tunnel enables geographically distributed user
network to transmit BPDU packets transparently over the specified VLAN VPN on the
operator’s network. This allows the user networks to participate in a uniform spanning
tree calculation while maintaining a separate spanning tree from the operator network.
As shown in
Figure 2-1, the upper part is the operator’s network, and the lower part is
the user network. The operator’s network comprises packet ingress/egress devices,
and the user 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
reconvert them back to their original formats at the egress. This is how transparent
transmission is implemented on the operator’s network.
