Example for Connecting Dot1q Termination Sub-interfaces to a VPLS Network

Networking Requirements

In the network example shown in Figure 8-11, VPLS is enabled on PE1 and PE2. CE1 is connected to PE1 and CE2 is connected to PE2. CE1 and CE2 are on the same VPLS network. PWs are established by using LDP as the VPLS signaling protocol, and VPLS is configured to connect CE1 and CE2.

Configuration Roadmap

  1. Configure a routing protocol on the backbone network to implement interworking between devices.

  2. Configure Dot1q sub-interfaces on PE interfaces connected to CEs so that the Dot1q sub-interfaces can connect to the VPLS network.

  3. Set up a remote LDP session between PEs.

  4. Establish tunnels between PEs to transmit service data.

  5. Enable MPLS L2VPN on PEs.

  6. Create VSIs on PEs and specify the signaling protocol as LDP.

NOTE:

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

Procedure

  1. Configure the VLAN to which each interface belongs, and assign IP addresses to VLANIF interfaces according to Figure 8-11.

    NOTE:
    • The AC-side and PW-side physical interfaces of a PE cannot be added to the same VLAN; otherwise, a loop may occur.

    • Ensure that each packet sent from a CE to a PE carries a VLAN tag.

  2. Configure an IGP, for example, OSPF.

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

    # Configure PE1.

    [PE1] router id 1.1.1.1
    [PE1] interface loopback 1
    [PE1-LoopBack1] ip address 1.1.1.1 32

    [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] quit
    [PE2-ospf-1] quit

    After the configuration is complete, run the display ip routing-table command on PE1, P, and PE2. You can view the routes that PE1, P, and PE2 have learned from each other. The following is the display on PE1:

    [PE1] display ip routing-table

  3. Configure basic MPLS functions and MPLS LDP.

    # Configure PE1.

    [PE1] mpls lsr-id 1.1.1.1
    [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

    # Configure P.

    [P] mpls lsr-id 2.2.2.2
    [P] mpls
    [P-mpls] quit
    [P] mpls ldp
    [P-mpls-ldp] quit
    [P] interface vlanif 20
    [P-Vlanif20] mpls
    [P-Vlanif20] mpls ldp
    [P-Vlanif20] quit
    [P] interface vlanif 30
    [P-Vlanif30] mpls
    [P-Vlanif30] mpls ldp
    [P-Vlanif30] quit

    # Configure PE2.

    [PE2] mpls lsr-id 3.3.3.3
    [PE2] mpls
    [PE2-mpls] quit
    [PE2] mpls ldp
    [PE2-mpls-ldp] quit

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

    After the configuration is complete, run the display mpls ldp session command on PE1, P, and PE2. You can see that the peer relationships are set up between PE1 and P, and between P and PE2. The status of the peer relationship is Operational. Run the display mpls ldp command to view the MPLS LDP configuration. The following is the display on PE1:

    [PE1] display mpls ldp session
     LDP Session(s) in Public Network
     Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
     A '*' before a session means the session is being deleted.

     ------------------------------------------------------------------------------
     TOTAL: 1 session(s) Found.
    

  4. Set up a remote LDP session 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 or PE2. You can see that the status of the peer relationship between PE1 and PE2 is Operational. The following is the display on PE1:

    [PE1] display mpls ldp session
     LDP Session(s) in Public Network
     Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
     A '*' before a session means the session is being deleted.
     ------------------------------------------------------------------------------
     PeerID            Status      LAM  SsnRole  SsnAge      KASent/Rcv

     3.3.3.3:0          Operational DU Passive  0000:00:00   2/2
     ------------------------------------------------------------------------------
     TOTAL: 2 session(s) Found.

  5. Enable MPLS L2VPN on PEs.

    # Configure PE1.

    [PE1] mpls l2vpn
    [PE1-l2vpn] quit

    # Configure PE2.

    [PE2] mpls l2vpn
    [PE2-l2vpn] quit

  6. Configure VSIs on PEs.

    # Configure PE1.

    [PE1] vsi a2 static
    [PE1-vsi-a2] pwsignal ldp
    [PE1-vsi-a2-ldp] vsi-id 2
    [PE1-vsi-a2-ldp] peer 3.3.3.3
    [PE1-vsi-a2-ldp] quit
    [PE1-vsi-a2] quit

    # Configure PE2.

    [PE2] vsi a2 static
    [PE2-vsi-a2] pwsignal ldp
    [PE2-vsi-a2-ldp] vsi-id 2
    [PE2-vsi-a2-ldp] peer 1.1.1.1
    [PE2-vsi-a2-ldp] quit
    [PE2-vsi-a2] quit

  7. Bind interfaces to VSIs on PEs.

    # Configure PE1.

    [PE1] vcmp role silent
    [PE1] interface gigabitethernet1/0/0
    [PE1-GigabitEthernet1/0/0] port link-type hybrid
    [PE1-GigabitEthernet1/0/0] quit
    [PE1] interface gigabitethernet1/0/0.1
    [PE1-GigabitEthernet1/0/0.1] dot1q termination vid 10
    [PE1-GigabitEthernet1/0/0.1] l2 binding vsi a2
    [PE1-GigabitEthernet1/0/0.1] quit

    # Configure PE2.

    [PE2] vcmp role silent
    [PE2] interface gigabitethernet2/0/0
    [PE2-GigabitEthernet2/0/0] port link-type hybrid
    [PE2-GigabitEthernet2/0/0] quit
    [PE2] interface gigabitethernet2/0/0.1
    [PE2-GigabitEthernet2/0/0.1] dot1q termination vid 10
    [PE2-GigabitEthernet2/0/0.1] l2 binding vsi a2
    [PE2-GigabitEthernet2/0/0.1] quit

  8. Verify the configuration.

    After the configuration is complete, run the display vsi name a2 verbose command on PE1. You can see that the VSI a2 sets up a PW to PE2 and the VSI status is Up.

    [PE1] display vsi name a2 verbose
