Configuration Task Summary
Table 8-1 describes the VLAN termination configuration tasks. The configuration tasks can be performed in any sequence.
Configuration Task | Applicable Scenario |
---|---|
Using a Dot1q Termination Sub-interface to Implement Inter-VLAN Communication |
A Layer 3 switch connects to user hosts residing in different VLANs through a Layer 3 Ethernet interface, and these user hosts need to communicate with each other. |
Configuring a Dot1q Termination Sub-interface and Connecting It to an L2VPN |
A carrier's network provides the L2VPN service for users. PEs function as user access devices and connect to CEs through sub-interfaces to access user networks. The data packets that CEs send to PEs carry one VLAN tag. Interworking is required between user networks. |
Configuring a Dot1q Termination Sub-interface and Connecting It to an L3VPN |
A carrier's network provides the L3VPN service for users. PEs function as user access devices and connect to CEs through sub-interfaces to access user networks. The data packets that CEs send to PEs carry one VLAN tag. Interworking is required between user networks. |
Configuring a QinQ Termination Sub-interface and Connecting It to an L2VPN |
A carrier's network provides the L2VPN service for users. PEs function as user access devices and connect to CEs through sub-interfaces to access user networks. The data packets that CEs send to PEs carry double VLAN tags. Interworking is required between user networks. |
Configuring a QinQ Termination Sub-interface and Connecting It to an L3VPN |
A carrier's network provides the L3VPN service for users. PEs function as user access devices and connect to CEs through sub-interfaces to access user networks. The data packets that CEs send to PEs carry double VLAN tags. Interworking is required between user networks. |
