Layer 2 Protocol Transparent Transmission Configuration
This chapter describes how to configure Layer 2 protocol transparent transmission.
- Introduction to Layer 2 Protocol Transparent Transmission
- Principles
- Application Environment
- Configuration Task Summary
- Licensing Requirements and Limitations for Layer 2 Protocol Transparent Transmission
- 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 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 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. - Configuration Examples
