23.10.3 Frame Tagging Examples
In the following example, both A and B are Service Provider’s Network (SPN)
customers with VPN tunnels between their head offices and branch offices
respectively. Both have an identical VLAN tag for their VLAN group. The service
provider can separate these two VLANs within its network by adding tag 37 to
distinguish customer A and tag 48 to distinguish customer B at edge device x and
then stripping those tags at edge device y as the data frames leave the network.

Figure 93 Frame Tagging Example

This example shows how to configure ports 1 and 2 on the switch to tag incoming
frames with the service provider’s VID of 37 (ports are connected to customer A
network). This example also shows how to set the priority for ports 1 and 2 to 3.
