Flexible QinQ application topology
As shown in the figure, the first user is assigned three VLANs that the tag values are 1001,
2001, 3001 respectively in DSLAM1. VLAN1001 corresponds to Broad Band Network,
VLAN2001 corresponds to VOIP, VLAN3001 corresponds to VOD. After the downlink port
enables flexible QinQ function, the packets will be packed with different external tags
according to VLAN ID of users. The packet with tag 1001 will be packed an external tag 1001
directly(This tag is unique in public network), enter Broad Band Network-VLAN1001 and
classfied to BRAS device. The packet with tag 2001(or 3001) will be packed an external tag
2001(or 3001) and classfied to SR device according to the flow rules. The second user can be
assigned different VLAN tags for different VLANs in DSLAM2. Notice: The assigned VLAN tag
