5.12.7 Example for Connecting QinQ Sub-interfaces to a VLL
Network
Networking Requirements
As shown in
VLANs.
A Martini VLL is set up between CE1 and CE2.
Switch1 is connected to CE1 and PE1.
Switch2 is connected to CE2 and PE2.
It is required that you configure selective QinQ on the interfaces connected to CEs so that the
switches add the VLAN tags specified by the carrier to the packets sent from CEs.
When a switch is connected to multiple CEs, the switch can add different VLAN tags to the
packets from different CEs, that is, packets with different VLAN tags. This saves VLAN IDs
on the public network.
