1.8 Configuring VLAN-VPN Tunnel
1.8.1 Introduction
The VLAN-VPN Tunnel function enables STP packets 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 users 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.
