Example for Configuring CBTS in a VLL over TE Scenario

Example for Configuring CBTS in a VLL over TE Scenario

Networking Requirements

In Figure 3-42, CE1 and CE2 belong to the same VLL network. They access the MPLS backbone network through PE1 and PE2, respectively. OSPF is used as an IGP on the MPLS backbone network.

It is required that a Martini VLL and the dynamic signaling protocol RSVP-TE be used to establish two MPLS TE tunnels between PE1 and PE2 to transmit VLL services. Each TE tunnel is assigned a specific priority. Interfaces that receive VLL packets have behavior aggregate classification enabled and trust 8021.p priority values so that they can forward VLL packets with a specific priority to a specific tunnel.

TE1 tunnel with ID 100 is established over the path PE1 –> P1 –> PE2, and TE2 tunnel with ID 200 is established over the path PE1 –> P2 –> PE2. AF1 is configured on TE1 interface, and AF2 is configured on TE2 interface. This configuration allows PE1 to forward traffic with service class AF1 along TE1 tunnel and traffic with service class AF2 along TE2 tunnel. The two tunnels can load-balance traffic based on priority values.

Note that if multiple tunnels with AF1 are established between PE1 and PE2, packets mapped to AF1 are load-balanced along these tunnels.

When CBTS is configured, do not configure the following services:
  • Seamless MPLS
  • Dynamic load balancing
Figure 3-42 CBTS networking in a VLL over TE scenario
NOTE:

Interfaces 1 through 10 in this example are GE0/2/1, GE0/2/2.1, GE0/2/3, GE0/5/1, GE0/5/0, GE0/3/1, GE0/4/1, GE0/3/3, GE0/4/0, GE0/1/1.1 respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  • Enable an IGP on the MPLS backbone network for devices on the backbone network to communicate.

  • Establish MPLS TE tunnels and configure a tunnel policy. For details about how to configure an MPLS TE tunnel, see "MPLS TE Configuration" in HUAWEI NE20E-S Universal Service Router Configuration Guide - MPLS.

  • Enable MPLS Layer 2 virtual private network (L2VPN) on the PEs.

  • Create a VLL, configure LDP as a signaling protocol, and bind the VLL to an AC interface on each PE.

  • Configure MPLS TE tunnels to transmit VLL packets.

Data Preparation

To complete the configuration, you need the following data:

  • OSPF area enabled with TE

  • VLL name and VLL ID

  • IP addresses of peers and tunnel policy

  • Name of AC interfaces bound to a VLL

  • Interface number and IP address of each tunnel interface, as well as destination IP address, tunnel ID, tunnel signaling protocol (RSVP-TE), and tunnel bandwidth to be specified on each tunnel interface

Procedure

  1. Assign an IP address to each interface.

    Configure the IP address and mask for each interface according to Figure 3-42.

  2. Enable MPLS, MPLS TE, MPLS RSVP-TE, and MPLS CSPF.

    On the nodes along each MPLS TE tunnel, enable MPLS, MPLS TE, and MPLS RSVP-TE both in the system view and the interface view. On the ingress node of each tunnel, enable MPLS CSPF in the system view.

  4. Configure tunnel interfaces.

    # Create tunnel interfaces on PEs, configure MPLS TE as a tunnel protocol and RSVP-TE as a signaling protocol, and specify priorities.

    # Configure PE1.

    [~PE1] interface Tunnel 10
    [*PE1-Tunnel10] ip address unnumbered interface loopback1
    [*PE1-Tunnel10] tunnel-protocol mpls te
    [*PE1-Tunnel10] destination 4.4.4.9

    [*PE1-Tunnel11] quit
    [*PE1] commit

    After completing the preceding configurations, run the display this interface command in the tunnel interface view. The command output shows that the Line protocol current state field is UP, indicating that an MPLS TE tunnel has been successfully established.

    Run the display tunnel-info all command in the system view on PE1. The command output shows that two TE tunnels destined for PE2 with the LSR ID of 4.4.4.9 have been established. The command output on PE2 is similar to that on PE1.

    <PE1> display tunnel-info all

  5. Configure MPLS TE explicit paths.

    Specify an explicit path for each tunnel with a physical interface on the P as the first next hop and a physical interface on PE2 as the second next hop to ensure that two tunnels are built over different links.

    # Configure PE1.

  6. Configure a remote LDP session.

    Establish a remote LDP session between PE1 and PE2.

    # Configure PE1.

    [PE1] mpls ldp
    [*PE1-mpls-ldp] quit
    [*PE1] mpls ldp remote-peer DTB1
    [*PE1-mpls-ldp-remote-DTB] remote-ip 4.4.4.9

    [*PE2] mpls ldp remote-peer DTB2
    [*PE2-mpls-ldp-remote-DTB2] remote-ip 1.1.1.9
    [*PE2] commit

    After completing the preceding configurations, run the display mpls ldp peer command. A remote LDP session has been established between the two PEs.

    The following command output uses the display on PE1.

    <PE1> display mpls ldp peer
    LDP Peer Information in Public network 
     A '*' before a peer means the peer is being deleted.

     TOTAL: 1 Peer(s) Found.
    

  7. Configure a tunnel policy.

    # Configure PE1.

    [PE1] tunnel-policy p1
    [*PE1-tunnel-policy-p1] tunnel select-seq cr-lsp load-balance-number 2
    [*PE1-tunnel-policy-p1] quit
    [*PE1] commit

  8. Enable MPLS L2VPN on PEs.

    # Configure PE1.

    [PE1]  mpls l2vpn
    [*PE1-l2vpn] quit
    [*PE1] commit

    # Configure PE2.

    [*PE2] mpls l2vpn
    [*PE2-l2vpn] quit
    [*PE2] commit

  9. Create a VLL on PEs and bind it to the tunnel policy.

    # Configure PE1.

    [PE1] interface gigabitethernet0/2/2.1
    [*PE1-GigabitEthernet0/2/2.1] vlan-type dot1q 10

    [*CE2-GigabitEthernet1/0/0.1] undo shutdown
    [*CE2-GigabitEthernet1/0/0.1] quit

  10. Verify the configuration.

    After completing the preceding configurations, run display mpls l2vc command on PE1.

    The command output shows that the values in the AC Status and VC State fields are up, and there are two tunnel IDs. Two tunnels have been established between PE1 and PE2.

    <PE1>display mpls l2vc interface GigabitEthernet0/2/2.1
