The two branches of the enterprise are connected to the (metropolitan area network) MAN
through the MA5600T/MA5603T/MA5608T. The upper-layer network must work in the Layer
2 mode, and must forward packets according to the VLAN and the MAC address.
On the MA5600T/MA5603T/MA5608T, the attribute of the upstream VLAN of user packets is
configured as QinQ private line service. A VLAN tunnel is created in Layer 2/Layer 3 MAN
for transmitting data carrying the VLAN tag. Different VLAN IDs are used for different
departments to achieve user isolation and data security. In this way, the service packets of the
enterprise private network can be transparently transmitted through the public network, and the
two branches can communicate with each other securely.
