21.3 Flexible QinQ Example
Figure 21-1 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 of the second user may be same with the first
user and the packet with tag will be also packed an external tag. In the above figure, the external tag of the
second user is different to the first user for distinguishing DSLAM location and locating the user finally.
The configuration in the following:
If the data flow of DSLAM1 enters the switch’s downlink port1, the configuration is as follows:
Switch(config)#class-map c1
