Application of Selective QinQ

Application of Selective QinQ

Selective QinQ networking is demonstrated in Figure 3-2, where "Switch" represents the S9300&S9300E.

Figure 3-2  Selective QinQ

The three enterprise networks shown in Figure 3-2 all need to transmit data, voice, and video services. The Switch can append an outer ISP VLAN tag to packets belonging to each kind of access service. For example:

  • Add an outer ISP VLAN tag VLAN 10 for data services belonging to VLAN 100, VLAN 600, and VLAN800 from the customer networks.

  • Add an outer ISP VLAN tag VLAN 30 for video services belonging to VLAN 450, VLAN 650, and VLAN850 from the customer networks.

Using selective QinQ, the S9300&S9300E can converge services and choose different paths for various services to more effectively facilitate network deployment.
