Example for Configuring an MCE

Networking Requirements

The headquarters and branches of a company need to communicate through MPLS VPN, and two services of the company must be isolated. To reduce hardware costs, the company wants the branch to connect to the PE through one CE.

As shown in Figure 1, the networking requirements are as follows:

  • CE1 and CE2 connect to the headquarters. CE1 belongs to vpna, and CE2 belongs to vpnb.
  • The MCE connects to vpna and vpnb of the branch through SwitchA and SwitchB.

Users in the same VPN need to communicate with each other, but users on different VPNs must be isolated.

Figure 1 Networking diagram for configuring an MCE

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure OSPF between PEs so that they can communicate and configure MP-IBGP to exchange VPN routing information.
  2. Configure basic MPLS capabilities and MPLS LDP on the PEs to establish LDP LSPs.
  3. Create VPN instances vpna and vpnb on the MCE and PEs to isolate services.
  4. Establish EBGP peer relationships between PE1 and its connected CEs, and import BGP routes to the VPN routing table of PE1.
  5. Configure routing between the MCE and VPN sites and between the MCE and PE2.

Procedure

  1. Configure VLANs on interfaces and assign IP addresses to the VLANIF interfaces and loopback interfaces according to Figure 1.

    # Configure PE1.

    <HUAWEI> system-view
[HUAWEI] sysname PE1
[PE1] interface loopback 1
[PE1-LoopBack1] ip address 1.1.1.9 32
[PE1-LoopBack1] quit
[PE1] vlan batch 30
[PE1] interface gigabitethernet 0/0/3
[PE1-GigabitEthernet0/0/3] port link-type trunk
[PE1-GigabitEthernet0/0/3] port trunk allow-pass vlan 30
[PE1-GigabitEthernet0/0/3] quit
[PE1] interface vlanif 30
[PE1-Vlanif30] ip address 172.1.1.1 24
[PE1-Vlanif30] quit

    # Configure PE2.

    <HUAWEI> system-view
[HUAWEI] sysname PE2
[PE2] interface loopback 1
[PE2-LoopBack1] ip address 2.2.2.9 32
[PE2-LoopBack1] quit
[PE2] vlan batch 30
[PE2] interface gigabitethernet 0/0/1
[PE2-GigabitEthernet0/0/1] port link-type trunk
[PE2-GigabitEthernet0/0/1] port trunk allow-pass vlan 30
[PE2-GigabitEthernet0/0/1] quit
[PE2] interface vlanif 30
[PE2-Vlanif30] ip address 172.1.1.2 24
[PE2-Vlanif30] quit

    # Configure CE1. The configuration on CE2, SwitchA and SwitchB is similar to the configuration on PE1 and is not mentioned here.

    <HUAWEI> system-view
[HUAWEI] sysname CE1
[CE1] vlan batch 10
[CE1] interface gigabitethernet 0/0/1
[CE1-GigabitEthernet0/0/1] port link-type trunk
[CE1-GigabitEthernet0/0/1] port trunk allow-pass vlan 10
[CE1-GigabitEthernet0/0/1] quit
[CE1] interface vlanif 10
[CE1-Vlanif10] ip address 10.1.1.1 24
[CE1-Vlanif10] quit

  2. Configure OSPF on PEs of the backbone network.

    # Configure PE1.

    [PE1] ospf
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[PE1-ospf-1-area-0.0.0.0] network 172.1.1.0 0.0.0.255
[PE1-ospf-1-area-0.0.0.0] quit
[PE1-ospf-1] quit

    # Configure PE2.

    [PE2] ospf
[PE2-ospf-1] area 0
[PE2-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
[PE2-ospf-1-area-0.0.0.0] network 172.1.1.0 0.0.0.255
[PE2-ospf-1-area-0.0.0.0] quit
[PE2-ospf-1] quit

    After the configuration is complete, PEs can obtain Loopback1 address of each other.

    The information displayed on PE2 is used as an example.

  3. Configure basic MPLS capabilities and MPLS LDP on the PEs to establish LDP LSPs.

    # Configure PE1.

    [PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp

[PE2] interface vlanif 30
[PE2-Vlanif30] mpls
[PE2-Vlanif30] mpls ldp
[PE2-Vlanif30] quit

    After the configuration is complete, run the display mpls ldp session command on the PEs. The command output shows that the MPLS LDP session between the PEs is in Operational state.

    The information displayed on PE2 is used as an example.

    [PE2] display mpls ldp session

  6. Establish an MP-IBGP peer relationship between PEs. Establish an EBGP peer relationship between PE1 and CE1, and between PE1 and CE2.

    # Configure PE1. The configuration on PE2 is similar to the configuration on PE1 and is not mentioned here.

    [PE1] bgp 100

    [CE1] bgp 65410
[CE1-bgp] peer 10.1.1.2 as-number 100
[CE1-bgp] import-route direct
[CE1-bgp] quit

    After the configuration is complete, run the display bgp vpnv4 all peer command on PE1. The command output shows that PE1 has established an IBGP peer relationship with PE2 and EBGP peer relationships with CE1 and CE2. The peer relationships are in Established state.

    [PE1] display bgp vpnv4 all peer

  7. Configure routing between the MCE and VPN sites.

    The MCE directly connects to vpna, and no routing protocol is used in vpna. Configure static routes to implement communication between the MCE and vpna.

    • Configure SwitchA.

      Assign IP address 192.168.1.1/24 to the interface connected to vpna. The configuration details are not mentioned here.

      [SwitchA] vlan batch 60
[SwitchA] interface gigabitethernet 0/0/1

    • Configure the MCE.

      [MCE] ip route-static vpn-instance vpna 192.168.1.0 24 10.3.1.1
    • Check the routes of vpna on the MCE.

      The preceding information shows that the MCE has a static route to vpna.

    The RIP protocol runs in vpnb. Configure RIP process 200 on the MCE and bind it to vpnb so that routes learned by RIP are added to the routing table of vpnb.

    • Configure the MCE.

      [MCE] rip 200 vpn-instance vpnb
[MCE-rip-200] version 2
[MCE-rip-200] network 10.0.0.0
[MCE-rip-200] import-route ospf 200
[MCE-rip-200] quit

    • Configure SwitchB.

      Assign IP address 192.168.2.1/24 to the interface connected to vpnb. The configuration is not provided here.

      [SwitchB] vlan batch 70
[SwitchB] interface gigabitethernet 0/0/1

      The preceding information shows that the MCE has learned the route to vpnb using RIP. The route to vpnb and the route to vpna (192.168.1.0) are maintained in different VPN routing tables so that users in the two VPNs are isolated from each other.

  8. Configure OSPF multi-instance between the MCE and PE2.

    # Configure PE2.

    To configure OSPF multi-instance between the MCE and PE2, complete the following tasks on PE2:
    • In the OSPF view, import BGP routes and advertise VPN routes of PE1 to the MCE.
    • In the BGP view, import routes of the OSPF processes and advertise the VPN routes of the MCE to PE1.

  9. Verify the configurations.

    After the configuration is complete, run the display ip routing-table vpn-instance command on the MCE to view the routes to the remote CEs. The VPN instance vpna is used as an example.

    [MCE] display ip routing-table vpn-instance vpna
