Example for Configuring Basic VPWS QoS Functions

After you configure basic VPWS QoS functions, you can check the bandwidth specified for each VPWS PW.

Networking Requirements

On the network shown in Figure 1, CE1 and CE2 connect to PE1 and PE2 through VLANs, respectively.

An LDP VPWS PW needs to be established between PE1 and PE2. PE2 needs to restrict the bandwidth of inbound traffic from its user side to ensure that the traffic from CE2 to CE1 enjoys a CIR of 2000 kbit/s and a PIR of 3000 kbit/s.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on PEs and the P on the backbone network to achieve connectivity between these devices and enable MPLS on them.

  2. Establish a TE tunnel between PEs to transmit user data, and configure a tunnel policy in which the TE tunnel is preferentially selected.

  3. Enable MPLS L2VPN on PEs and create VCs.

  4. Configure VLAN sub-interfaces so that CEs can access PEs through VLANs.

  5. Configure QoS parameters on GE 0/1/0.1 of PE2.

Data Preparation

To complete the configuration, you need the following data:

  • VLAN sub-interface numbers

  • Name of the remote peer of each PE

  • VC ID

  • CIR

  • PIR

Procedure

  1. Configure basic functions on CEs.

    # Configure CE1.

[*CE2] commit

  2. Configure an IGP on the MPLS backbone network. OSPF is used in this example.

    Assign an IP address to each interface on PEs and the P based on Figure 1. When configuring OSPF, advertise the 32-bit IP addresses of loopback interfaces, which are used as LSR IDs, on the PEs and P.

  3. Configure an MPLS TE tunnel.
    1. Enable MPLS, MPLS TE, and MPLS RSVP-TE both globally and on specific interfaces on each node along the MPLS TE tunnel. Enable MPLS TE CSPF in the system view of the tunnel's ingress.

    3. Configure MPLS TE attributes for links.

      Configure the maximum link bandwidth and maximum reservable link bandwidth for each interface along the tunnel.

      # Configure PE1.

      [~PE1] interface gigabitethernet 0/1/8
[~PE1-GigabitEthernet0/1/8] mpls te bandwidth max-reservable-bandwidth 5000

[*PE2-GigabitEthernet0/1/0] quit
[*PE2] commit

    4. Configure tunnel interfaces.

      # Create tunnel interfaces on PEs, set the tunnel protocol to MPLS TE and the signaling protocol to RSVP-TE, and specify bandwidth.

      # Configure PE1.

      [~PE1] interface Tunnel 10
[*PE1-Tunnel10] ip address unnumbered interface loopback1
[*PE1-Tunnel10] tunnel-protocol mpls te
[*PE1-Tunnel10] mpls te signal-protocol rsvp-te
[*PE1-Tunnel10] destination 3.3.3.9
[*PE1-Tunnel10] mpls te tunnel-id 101
[*PE1-Tunnel10] mpls te bandwidth ct0 2000
[*PE1-Tunnel10] quit
[*PE1] commit

      # Configure PE2.

      [~PE2] interface Tunnel 10

[*PE2-Tunnel10] mpls te tunnel-id 101
[*PE2-Tunnel10] mpls te bandwidth ct0 2000
[*PE2-Tunnel10] quit
[*PE2] commit

      After the configuration is complete, run the display this interface command in the tunnel interface view. In the command output, Line protocol current state is UP, indicating that the MPLS TE tunnel has been established.

      [~PE1-Tunnel10] display this interface

  4. Establish a remote LDP session between PEs.

    # Configure PE1.

    [~PE1] mpls ldp
[*PE1] mpls ldp remote-peer 3.3.3.9
[*PE1-mpls-ldp-remote-3.3.3.9] remote-ip 3.3.3.9

[*PE1] commit

    # Configure PE2.

[*PE2-mpls-ldp-remote-1.1.1.9] remote-ip 1.1.1.9
[*PE2-mpls-ldp-remote-1.1.1.9] quit
[*PE2] commit

    After the configuration is complete, run the display mpls ldp session command on PE1 to check LDP session information. The command output shows that PE1 has established an LDP session with PE2.

    The following example uses the command output on PE1.

    [~PE1] display mpls ldp session

  5. Configure a tunnel policy in which the TE tunnel is preferentially selected and establish a VPWS connection.

    # Configure PE1.

    [~PE1] tunnel-policy policy1
[*PE1-tunnel-policy-policy1] tunnel select-seq te load-balance-number 1

[*PE2-GigabitEthernet0/1/8.1] mpls l2vc 1.1.1.9 101 tunnel-policy policy1
[*PE2-GigabitEthernet0/1/8.1] quit
[*PE2] commit

  6. Configure QoS parameters on GE0/1/8.1 of PE2 to ensure VPWS bandwidth.

    # Configure QoS parameters.

    [~PE2] interface gigabitethernet 0/1/8.1
[~PE2-GigabitEthernet0/1/8.1] mpls l2vpn qos cir 2000 pir 3000
[*PE2-GigabitEthernet0/1/8.1] quit
[*PE2] commit

  7. Verify the configuration.

    Check L2VPN connection information on PEs. You can find that an L2VC has been established and is up.

    The following example uses the command output on PE2.

    [~PE2] display mpls l2vc interface gigabitethernet 0/1/8.1

    CE1 and CE2 can ping each other.

    The following example uses the command output on CE1.
