Example for Connecting a QinQ Sub-interface to a VLL Network

Example for Connecting a QinQ Sub-interface to a VLL Network

Networking Requirements

As shown in Figure 8-10, CE1 and CE2 are connected to PE1 and PE2 respectively through VLANs.

A Martini VLL is created between CE1 and CE2 so that user networks connected to CE1 and CE2 can communicate.

Figure 8-10  Networking diagram for configuring a sub-interface for dot1q VLAN tag termination to access a VLL network

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on devices (PE and P) of the backbone network to implement interworking, and enable MPLS.

  2. Use the default tunnel policy to create an LSP and configure the LSP for data transmission.

  3. Enable MPLS L2VPN and create VC connections on PEs.

  4. Configure QinQ sub-interfaces on PE interfaces connected to CEs to implement VLL access.

Procedure

  1. Configure IP addresses for interfaces on CEs, PEs, and P according to Figure 8-10.

    # CE1 is used as an example. The configuration details of other devices are not mentioned here.

    <Huawei> system-view
    [Huawei] sysname CE1
    [CE1] interface gigabitethernet 1/0/0.1
    [CE1-GigabitEthernet1/0/0.1] ip address 10.100.1.1 255.255.255.0
    [CE1-GigabitEthernet1/0/0.1] quit

  2. Configure CEs to send double-tagged packets to PEs.

    # Here, the inner VLAN ID is VLAN 10 and outer VLAN ID is VLAN 100.

    # Configure CE1.

    [CE1] interface gigabitethernet 1/0/0.1
    [CE1-GigabitEthernet1/0/0.1] qinq termination pe-vid 100 ce-vid 10
    [CE1-GigabitEthernet1/0/0.1] quit

    # Configure CE2.

    [CE2] interface gigabitethernet 1/0/0.1
    [CE2-GigabitEthernet1/0/0.1] qinq termination pe-vid 100 ce-vid 10
    [CE2-GigabitEthernet1/0/0.1] quit

  3. Configure an IGP on the MPLS backbone network. OSPF is used as an example.

    # Configure PE1, P, and PE2 to advertise 32-bit loopback interface addresses as the LSR IDs.

    # PE1 is used as an example. The configuration details of other devices are not mentioned here.

    [PE1] ospf 1
    [PE1-ospf-1] area 0
    [PE1-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
    [PE1-ospf-1-area-0.0.0.0] network 10.10.1.9 0.0.0.0
    [PE1-ospf-1-area-0.0.0.0] quit
    [PE1-ospf-1] quit
    

  4. Configure basic MPLS functions and MPLS LDP on the MPLS network.

    # Configure PE1.

    [PE1] mpls lsr-id 10.10.1.9
    [PE1] mpls
    [PE1-mpls] quit
    [PE1] mpls ldp
    [PE1-mpls-ldp] quit
    [PE1] interface gigabitethernet 2/0/0
    [PE1-GigabitEthernet2/0/0] mpls
    [PE1-GigabitEthernet2/0/0] mpls ldp
    [PE1-GigabitEthernet2/0/0] quit

    # Configure P.

    [P] mpls lsr-id 10.20.2.9
    [P] mpls
    [P-mpls] quit
    [P] mpls ldp
    [P-mpls-ldp] quit
    [P] interface gigabitethernet 2/0/0
    [P-GigabitEthernet2/0/0] mpls
    [P-GigabitEthernet2/0/0] mpls ldp
    [P-GigabitEthernet2/0/0] quit
    [P] interface gigabitethernet 1/0/0
    [P-GigabitEthernet1/0/0] mpls
    [P-GigabitEthernet1/0/0] mpls ldp
    [P-GigabitEthernet1/0/0] quit

    # Configure PE2.

    [PE2] mpls lsr-id 10.30.3.9
    [PE2] mpls
    [PE2-mpls] quit
    [PE2] mpls ldp
    [PE2-mpls-ldp] quit
    [PE2] interface gigabitethernet 1/0/0
    [PE2-GigabitEthernet1/0/0] mpls
    [PE2-GigabitEthernet1/0/0] mpls ldp
    [PE2-GigabitEthernet1/0/0] quit

  5. Set up a remote LDP session between PEs.

    # Configure PE1.

    [PE1] mpls ldp remote-peer 10.30.3.9
    [PE1-mpls-ldp-remote-10.30.3.9] remote-ip 10.30.3.9
    [PE1-mpls-ldp-remote-10.30.3.9] quit

    # Configure PE2.

    [PE2] mpls ldp remote-peer 10.10.1.9
    [PE2-mpls-ldp-remote-10.10.1.9] remote-ip 10.10.1.9
    [PE2-mpls-ldp-remote-10.10.1.9] quit

    After the configuration is complete, run the display mpls ldp session command on PE1 to view the LDP session setup. You can see that an LDP session is set up between PE1 and PE2.

    Take the display on PE1 for example.

    [PE1] display mpls ldp session

  6. Enable MPLS L2VPN and create VCs on PEs.

    # On PE1, create a VC on GE1/0/0.1 connected to CE1.

    [PE1] mpls l2vpn
    [PE1-l2vpn] quit
    [PE1] interface gigabitethernet 1/0/0.1

    # On PE2, create a VC on GE2/0/0.1 connected to CE2.

    [PE2] mpls l2vpn
    [PE2-l2vpn] quit

    [PE2-GigabitEthernet2/0/0.1] mpls l2vc 10.10.1.9 101
    [PE2-GigabitEthernet2/0/0.1] quit

  7. Verify the configuration.

    # Check L2VPN connections on PEs. You can see that an L2VC connection has been set up and is in Up state.

    [PE1] display mpls l2vc interface gigabitethernet 1/0/0.1
