Example for Connecting a VLAN Stacking Sub-interface to a VLL Network

Networking Requirements

As shown in Figure 10-16, CE1 and CE2 are connected to PE1 and PE2 respectively through VLANs.

A Martini virtual leased line (VLL) is set up between CE1 and CE2.

Switch1 is connected to CE1 and PE1.

Switch2 is connected to CE2 and PE2.

Switch1 forwards packets sent from CE1 without changing their VLAN tags.

Selective QinQ needs to be configured on the interface on Switch2 connected to CE2 so that Switch2 can add the carrier-specified VLAN tag to the packets sent from CE2.

The packets sent from Switch1 to PE1 carry only one VLAN tag, and the packets sent from Switch2 to PE2 carry two VLAN tags. To allow CE1 and CE2 to communicate with each other, you need to configure VLAN stacking on the sub-interface of PE1 connected to Switch1, and connect the sub-interface to the VLL network.

When a switch is connected to multiple CEs, the switch can add the same outer VLAN tag to packets with different VLAN tags from different CEs, thereby conserving VLAN IDs on the public network.

NOTE:

VLAN termination sub-interfaces cannot be created on a VCMP client.

Configuration Roadmap

The configuration roadmap is as follows:

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

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

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

  4. On PE1, configure VLAN stacking on the sub-interface connected to Switch1, configure VLAN stacking on the sub-interface, and create a VC connection to connect the sub-interface to the VLL network.

  5. On PE2, create a sub-interface on the interface connected to Switch2, configure QinQ on the sub-interface, and create a VC connection from the sub-interface to the VLL network.

  6. On Switch1, add the interface connected to CE1 to a specified VLAN.

  7. On Switch2, configure selective QinQ on the interface connected to CE2.

Procedure

  1. Create VLANs on the CE, PE, and P devices, add interfaces to the VLANs, and assign IP addresses to VLANIF interfaces according to Figure 10-16.

    [P-ospf-1-area-0.0.0.0] quit
    [P-ospf-1] quit

    # Configure PE2.

    [PE2] router id 3.3.3.3
    [PE2] interface loopback 1
    [PE2-LoopBack1] ip address 3.3.3.3 32
    [PE2-LoopBack1] quit
    [PE2] ospf 1
    [PE2-ospf-1] area 0
    [PE2-ospf-1-area-0.0.0.0] network 3.3.3.3 0.0.0.0

    [PE2-ospf-1] quit

    # After the configuration is complete, PE1, P, and PE2 can establish OSPF neighbor relationships. Run the display ospf peer command to verify that the OSPF neighbor relationship status is Full. Run the display ip routing-table command to verify that the PEs learn the route to the Loopback1 interface of each other. The following is the display on PE1:

    [PE1] mpls
    [PE1-mpls] quit
    [PE1] mpls ldp
    [PE1-mpls-ldp] quit
    [PE1] interface vlanif 20
    [PE1-Vlanif20] mpls
    [PE1-Vlanif20] mpls ldp
    [PE1-Vlanif20] quit

    [PE2-Vlanif30] mpls
    [PE2-Vlanif30] mpls ldp
    [PE2-Vlanif30] quit

  5. Create remote LDP sessions between PEs.

    # Configure PE1.

    [PE1] mpls ldp remote-peer 3.3.3.3
    [PE1-mpls-ldp-remote-3.3.3.3] remote-ip 3.3.3.3
    [PE1-mpls-ldp-remote-3.3.3.3] quit

    # Configure PE2.

    [PE2] mpls ldp remote-peer 1.1.1.1
    [PE2-mpls-ldp-remote-1.1.1.1] remote-ip 1.1.1.1
    [PE2-mpls-ldp-remote-1.1.1.1] quit

    After the configuration is complete, run the display mpls ldp session command on PE1 to view the LDP session setup. The following output indicates that an LDP session has been set up between PE1 and PE2.

    [PE1] display mpls ldp session

  6. Enable MPLS L2VPN on PEs and set up VC connections.

    # On PE1, create a VC connection on GigabitEthernet1/0/0.1 connected to Switch1.

    [PE1] mpls l2vpn
    [PE1-l2vpn] quit
    [PE1] vcmp role silent

  7. Verify the configuration.

    Check the L2VPN connections on PEs. The following output on PE1 indicates that an L2VC connection has been set up and is in Up state.

    [PE1] display mpls l2vc interface gigabitethernet1/0/0.1
