Item Description Task

Configuring interface-based Layer 2 protocol transparent transmission

When each interface of a backbone device is connected to only one user network and Layer 2 protocol packets sent from the user network do not need VLAN tags, configure interface-based Layer 2 protocol transparent transmission on the interface connected to the user network. This configuration allows Layer 2 protocol packets to be transparently transmitted on the backbone network.

Configuring VLAN-based Layer 2 protocol transparent transmission

When each interface of a backbone device is connected to multiple user networks and Layer 2 protocol packets sent from user networks contain VLAN tags, configure VLAN-based Layer 2 protocol transparent transmission. This configuration allows Layer 2 protocol packets to be transparently transmitted on the backbone network.

Configuring basic QinQ-based Layer 2 protocol transparent transmission

When each interface of a backbone device is connected to multiple user networks and Layer 2 protocol packets sent from user networks contain VLAN tags, configure basic QinQ-based Layer 2 protocol transparent transmission. This configuration allows Layer 2 protocol packets to be transparently transmitted on the backbone network and reduces VLAN IDs that the carrier uses.
