Example for Configuring BGP/MPLS IP VPN

Example for Configuring BGP/MPLS IP VPN

Networking Requirements

As shown in Figure 3-46:
  • CE1 connects to the headquarters R&D area of a company, and CE3 connects to the branch R&D area. CE1 and CE3 belong to vpna.
  • CE2 connects to the headquarters non-R&D area, and CE4 connects to the branch non-R&D area. CE2 and CE4 belong to vpnb.

BGP/MPLS IP VPN needs to be deployed for the company to ensure secure communication between the headquarters and branch.

Figure 3-46  Networking diagram for configuring BGP/MPLS IP VPN

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure OSPF between the P and PEs to ensure IP connectivity on the backbone network.
  2. Configure basic MPLS capabilities and MPLS LDP on the P and PEs to establish MPLS LSP tunnels for VPN data transmission on the backbone network.
  3. Configure MP-IBGP on PE1 and PE2 to enable them to exchange VPN routing information.
  4. Configure VPN instances vpna and vpnb on PE1 and PE2. Set the VPN target of vpna to 111:1 and the VPN target of vpnb to 222:2. This configuration allows users in the same VPN to communicate with each other and isolates users on different VPNs. Bind the PE interfaces connected to CEs to the corresponding VPN instances to provide access for VPN users.
  5. Configure EBGP on the CEs and PEs to exchange VPN routing information.

Procedure

  1. Configure an IGP on the MPLS backbone network so that PEs and P can communicate with each other.

    After the configuration is complete, OSPF neighbor relationships are established between PE1 and P, and between PE2 and P. Run the display ospf peer command. The command output shows that the neighbor status is Full. Run the display ip routing-table command. The command output shows that PEs have learned the routes to Loopback1 of each other.

    The information displayed on PE1 is used as an example.

    [PE2-Vlanif60] quit

    After the configuration is complete, LDP sessions are established between PE1 and the P and between the P and PE2. Run the display mpls ldp session command. The command output shows that the Status field is Operational. Run the display mpls ldp lsp command. Information about the established LDP LSPs is displayed.

    The information displayed on PE1 is used as an example.

  3. Configure VPN instances on PEs and bind the interfaces connected to CEs to the VPN instances.

    # Configure PE1.

    [PE1] ip vpn-instance vpna
    [PE1-vpn-instance-vpna] route-distinguisher 100:1
    [PE1-vpn-instance-vpna-af-ipv4] vpn-target 111:1 both
    [PE1-vpn-instance-vpna-af-ipv4] quit
    [PE1-vpn-instance-vpna] quit
    [PE1] ip vpn-instance vpnb
    [PE1-vpn-instance-vpnb] route-distinguisher 100:2
    [PE1-vpn-instance-vpnb-af-ipv4] vpn-target 222:2 both
    [PE1-vpn-instance-vpnb-af-ipv4] quit
    [PE1-vpn-instance-vpnb] quit
    [PE1] interface vlanif 10
    [PE1-Vlanif10] ip binding vpn-instance vpna
    [PE1-Vlanif10] ip address 10.1.1.2 24
    [PE1-Vlanif10] quit
    [PE1] interface vlanif 20
    [PE1-Vlanif20] ip binding vpn-instance vpnb
    [PE1-Vlanif20] ip address 10.2.1.2 24
    [PE1-Vlanif20] quit

    # Configure PE2.

    [PE2] ip vpn-instance vpna
    [PE2-vpn-instance-vpna] route-distinguisher 200:1
    [PE2-vpn-instance-vpna-af-ipv4] vpn-target 111:1 both
    [PE2-vpn-instance-vpna-af-ipv4] quit
    [PE2-vpn-instance-vpna] quit
    [PE2] ip vpn-instance vpnb
    [PE2-vpn-instance-vpnb] route-distinguisher 200:2
    [PE2-vpn-instance-vpnb-af-ipv4] vpn-target 222:2 both
    [PE2-vpn-instance-vpnb-af-ipv4] quit
    [PE2-vpn-instance-vpnb] quit
    [PE2] interface vlanif 40
    [PE2-Vlanif40] ip binding vpn-instance vpna
    [PE2-Vlanif40] ip address 10.3.1.2 24
    [PE2-Vlanif40] quit
    [PE2] interface vlanif 50
    [PE2-Vlanif50] ip binding vpn-instance vpnb
    [PE2-Vlanif50] ip address 10.4.1.2 24
    [PE2-Vlanif50] quit

    # Assign IP addresses to the interfaces on the CE1 according to Figure 3-46. The configuration procedure is not provided here. The configuration on CE2, CE3, and CE4 is similar to the configuration on CE1 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
    

    After the configuration is complete, run the display ip vpn-instance verbose command on the PEs to check the configuration of VPN instances. Each PE can ping its connected CE.

    NOTE:

    If a PE has multiple interfaces bound to the same VPN instance, specify a source IP addresses by setting -a source-ip-address in the ping -vpn-instance vpn-instance-name -a source-ip-address dest-ip-address command to ping the a remote CE. If the source IP address is not specified, the ping fails.

    PE1 and CE1 are used as an example.

  4. Establish EBGP peer relationships between PEs and CEs and import VPN routes into BGP.

    # Configure CE1. The configuration on CE2, CE3, and CE4 is similar to the configuration on CE1 and is not mentioned here.

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

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

    [PE1] bgp 100
    [PE1-bgp] ipv4-family vpn-instance vpna
    [PE1-bgp-vpna] peer 10.1.1.1 as-number 65410

    [PE1-bgp-vpna] quit
    [PE1-bgp] ipv4-family vpn-instance vpnb

    [PE1-bgp-vpnb] import-route direct
    [PE1-bgp-vpnb] quit
    [PE1-bgp] quit

    After the configuration is complete, run the display bgp vpnv4 vpn-instance peer command on the PEs. The command output shows that BGP peer relationships have been established between the PEs and CEs.

    The peer relationship between PE1 and CE1 is used as an example.

    [PE1] display bgp vpnv4 vpn-instance vpna peer
    
     BGP local router ID : 1.1.1.9
     Local AS number : 100
     VPN-Instance vpna, Router ID 1.1.1.9:

  5. Establish MP-IBGP peer relationships between PEs.

    # Configure PE1.

    [PE1] bgp 100
    [PE1-bgp] peer 3.3.3.9 as-number 100
    [PE1-bgp] peer 3.3.3.9 connect-interface loopback 1
    [PE1-bgp] ipv4-family vpnv4
    [PE1-bgp-af-vpnv4] peer 3.3.3.9 enable
    [PE1-bgp-af-vpnv4] quit
    [PE1-bgp] quit

    # Configure PE2.

    [PE2] bgp 100
    [PE2-bgp] peer 1.1.1.9 as-number 100
    [PE2-bgp] peer 1.1.1.9 connect-interface loopback 1
    [PE2-bgp] ipv4-family vpnv4
    [PE2-bgp-af-vpnv4] peer 1.1.1.9 enable
    [PE2-bgp-af-vpnv4] quit
    [PE2-bgp] quit

    After the configuration is complete, run the display bgp peer or display bgp vpnv4 all peer command on the PEs. The command output shows that BGP peer relationships have been established between the PEs.

  6. Verify the configurations.

    Run the display ip routing-table vpn-instance command on the PEs to view the routes to the remote CEs.

    The information displayed on PE1 is used as an example.

    CEs in the same VPN can ping each other, whereas CEs on different VPNs cannot.

    For example, CE1 can ping CE3 at 10.3.1.1 but cannot ping CE4 at 10.4.1.1.
