100.2 Command Examples
In the following example figure, 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.
