1.7 QinQ Configuration Examples
1.7.1 Traffic Classification-Based Nested VLAN Configuration Example
I. Network requirements
z
As shown in
Figure 1-4
, two types of services run on the S9512 switch: common
internet access and on-demand multicast video. Traffic classification-based
nested VLAN encapsulates different tags at the exterior layer to distinguish the
two services based on the packet tag sent by the digital subscriber line access
multiplexer (DSLAM).
z
VLAN 100 to VLAN 512 comprise home users that have access to the Internet. For
the packets in this VLAN range, S9512 needs to encapsulate another external tag
of VLAN 1000, and then sends the packets to BRAS.
z
VLAN 600 is a multicast VLAN. When receiving a packet with the tag of VLAN 600,
S9512 does not process the packet.
