Example for Configuring Inter-AS IPv6 VPN Option A

Networking Requirements

The headquarters and branches of a company connect to networks of different carriers. To enable the headquarters and branches to communicate, Inter-AS BGP/MPLS IPv6 VPN needs to be implemented. As shown in Figure 1, CE1 is located in the headquarters and connects to PE1 in AS 100. CE2 is located at the branch and connects to PE2 in AS 200. Both CE1 and CE2 belong to VPN1.

Figure 1 Networking diagram for configuring inter-AS IPv6 VPN Option A

Configuration Roadmap

Inter-AS Option A can be deployed to meet the company's requirement. The configuration roadmap is as follows:

  1. On the MPLS backbone networks in AS 100 and AS 200, configure an IGP protocol to enable the PEs and ASBR-PEs to communicate with each other.
  2. Configure basic MPLS capabilities and MPLS LDP on the MPLS backbone network to establish LDP LSPs in each AS.
  3. Establish an MP-IBGP peer relationship between the PE and ASBR-PE in each AS to exchange VPN routing information.
  4. Configure a VPN instance on the PE in each AS and bind the interface connected to the CE to the VPN instance.
  5. Establish an EBGP peer relationship between the PE and CE in each AS to exchange VPN routing information.
  6. Create an IPv6 VPN instance on each ASBR-PE and bind the instance to the interface connected to the other ASBR-PE (regarding the ASBR-PE as its CE). Establish an EBGP peer relationship between the ASBR-PEs to exchange VPN routing information.

Procedure

  1. Create VLANs, configure the allowed 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] ipv6
[PE1] vlan batch 10 11
[PE1] interface gigabitethernet 0/0/1
[PE1-GigabitEthernet0/0/1] port link-type trunk
[PE1-GigabitEthernet0/0/1] port trunk allow-pass vlan 11
[PE1-GigabitEthernet0/0/1] quit
[PE1] interface gigabitethernet 0/0/2
[PE1-GigabitEthernet0/0/2] port link-type trunk
[PE1-GigabitEthernet0/0/2] port trunk allow-pass vlan 10
[PE1-GigabitEthernet0/0/2] quit
[PE1] interface vlanif 11
[PE1-Vlanif11] ip address 172.1.1.2 24
[PE1-Vlanif11] quit
[PE1] interface vlanif 10
[PE1-Vlanif10] ipv6 enable
[PE1-Vlanif10] ipv6 address 2001::2 64
[PE1-Vlanif10] quit

    The configuration on PE2, CE1, CE2, ASBR-PE1, and ASBR-PE2 is similar to the configuration on PE1 and is not mentioned here.

  2. On the MPLS backbone networks in AS 100 and AS 200, configure an IGP protocol to enable the PEs and ASBR-PEs to communicate with each other.

    # 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

    The configuration on PE2 and ASBR-PEs is similar to the configuration on PE1 and is not mentioned here.

    After the configuration is complete, the ASBR-PE and PE in the same AS can establish an OSPF neighbor relationship. Run the display ospf peer command to verify that the status of the neighbor relationship is Full.

    The ASBR-PE and PE in the same AS have obtained the address of Loopback1 interface of each other and can ping Loopback1 interface address of each other.

  3. Configure basic MPLS capabilities and MPLS LDP on the MPLS backbone networks of AS 100 and AS 200 respectively and establish MPLS LDP LSPs.

    # Configure basic MPLS capabilities on PE1 and enable LDP on the interface connected to ASBR-PE1.

    [PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 11
[PE1-Vlanif11] mpls
[PE1-Vlanif11] mpls ldp
[PE1-Vlanif11] quit

    # Configure basic MPLS capabilities on ASBR-PE1 and enable LDP on the interface connected to PE1.

    [ASBR-PE1] mpls lsr-id 2.2.2.9
[ASBR-PE1] mpls
[ASBR-PE1-mpls] quit
[ASBR-PE1] mpls ldp
[ASBR-PE1-mpls-ldp] quit
[ASBR-PE1] interface vlanif 11
[ASBR-PE1-Vlanif11] mpls
[ASBR-PE1-Vlanif11] mpls ldp
[ASBR-PE1-Vlanif11] quit

    # Configure basic MPLS capabilities on ASBR-PE2 and enable LDP on the interface connected to PE2.

    [ASBR-PE2] mpls lsr-id 3.3.3.9
[ASBR-PE2] mpls
[ASBR-PE2-mpls] quit
[ASBR-PE2] mpls ldp
[ASBR-PE2-mpls-ldp] quit
[ASBR-PE2] interface vlanif 22
[ASBR-PE2-Vlanif22] mpls
[ASBR-PE2-Vlanif22] mpls ldp
[ASBR-PE2-Vlanif22] quit

    # Configure basic MPLS capabilities on PE2 and enable LDP on the interface connected to ASBR-PE2.

    [PE2] mpls lsr-id 4.4.4.9
[PE2] mpls
[PE2-mpls] lsp-trigger all
[PE2-mpls] quit
[PE2] mpls ldp
[PE2-mpls-ldp] quit
[PE2] interface vlanif 22
[PE2-Vlanif22] mpls
[PE2-Vlanif22] mpls ldp
[PE2-Vlanif22] quit

    After the configuration is complete, the PE and ASBR-PE in the same AS can establish an LDP peer relationship. Run the display mpls ldp session command on the PE and ASBR-PE, and you can see that the status is Operational.

  4. Configure the basic BGP/MPLS IPv6 VPNs in AS 100 and AS 200.

    The VPN targets of the IPv6 VPN instances on the ASBR-PE and PE in an AS must match. In different ASs, the VPN targets of the PEs do not need to match.

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

    [CE1] interface vlanif 10
[CE1-Vlanif10] ipv6 enable
[CE1-Vlanif10] ipv6 address 2001::1 64
[CE1-Vlanif10] quit
[CE1] bgp 65001
[CE1-bgp] router-id 10.10.10.10
[CE1-bgp] peer 2001::2 as-number 100

[CE1-bgp-af-ipv6] import-route direct
[CE1-bgp-af-ipv6] quit
[CE1-bgp] quit

    # On PE1, establish an EBGP peer relationship with CE1. The configuration on PE2 is similar to the configuration on PE1 and is not mentioned here.

[PE1-bgp6-vpn1] peer 2001::1 as-number 65001
[PE1-bgp6-vpn1] import-route direct
[PE1-bgp6-vpn1] quit
[PE1-bgp] quit

    # On PE1: establish an MP-IBGP peer relationship with ASBR-PE1. The configuration on PE2 is similar to the configuration on PE1 and is not mentioned here.

    [PE1] bgp 100

[PE1-bgp] quit

    # On ASBR-PE1: establish an MP-IBGP peer relationship with PE1. The configuration on ASBR-PE2 is similar to the configuration on ASBR-PE1 and is not mentioned here.

    [ASBR-PE1] bgp 100
[ASBR-PE1-bgp] peer 1.1.1.9 as-number 100
[ASBR-PE1-bgp] peer 1.1.1.9 connect-interface loopback 1
[ASBR-PE1-bgp] ipv6-family vpnv6
[ASBR-PE1-bgp-af-vpnv6] peer 1.1.1.9 enable
[ASBR-PE1-bgp-af-vpnv6] quit
[ASBR-PE1-bgp] quit

    After the configuration is complete, run the display bgp vpnv6 vpn-instance peer command on the PEs. The command output shows that the BGP peer relationships have been established between the PEs and CEs and are in Established state. Run the display bgp vpnv6 all peer command on the PEs. The command output shows that the BGP peer relationships have been established between the PEs and CEs, and between the PEs and ASBR-PEs, and are in Established state.

    The information displayed on PE1 is used as an example.

  5. Configure inter-AS VPN Option A.

    # On ASBR-PE1, create an IPv6 VPN instance and bind the instance to the interface connected to ASBR-PE2 (ASBR-PE1 regards ASBR-PE2 as its own CE).

[ASBR-PE2-bgp6-vpn1] import-route direct
[ASBR-PE2-bgp6-vpn1] quit
[ASBR-PE2-bgp] quit

    After the configuration is complete, run the display bgp vpnv6 vpn-instance peer command on an ASBR-PE. The command output shows that a BGP peer relationship has been established between the ASBR-PEs and is in Established state.

  6. Verify the configuration.

    After the configuration is complete, CE1 and CE2 learn routes to interfaces on each other and can ping each other successfully.
