5.12.12 Example for Connecting QinQ Sub-interfaces to a VPLS
Network
Networking Requirements
As shown in
through PE1, and CE2 is connected to Switch2 through PE2. CE1 and CE2 belong to the same
VSI. LDP is used as the VPLS signaling protocol to set up the PW and Martini VPLS is
configured to enable CE1 and CE2 to communicate with each other.
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.
