Configuring 2:2 VLAN Mapping
Context
QinQ is used to send double-tagged packets, which prevents the conflict between C-VLAN IDs and S-VLAN IDs and differentiates services and users. However, the interface will discard the packets because C-VLAN IDs are different from S-VLAN IDs. To ensure communication continuity, configure 2:2 VLAN mapping on the PE and replace double C-VLAN tags with double S-VLAN tags.
