Summary of Layer 2 Protocol Transparent Transmission Configuration Tasks

Summary of Layer 2 Protocol Transparent Transmission Configuration Tasks

Table 20-1 lists the configuration task summary of Layer 2 protocol transparent transmission.

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 Interface-based Layer 2 Protocol Transparent Transmission

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 VLAN-based Layer 2 Protocol Transparent Transmission

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.

Configuring QinQ-based Layer 2 Protocol Transparent Transmission

Configuring VPLS-based Layer 2 protocol transparent transmission

When the backbone network is the L2VPN that is built based on VPLS, you can configure VPLS-based Layer 2 protocol transparent transmission so that Layer 2 protocol packets can be transmitted on the backbone network.
