Example for Configuring an MCE IPv6 Device

Networking Requirements

The headquarters and branch of a company need to communicate through MPLS VPN, and two IPv6 services of the company must be isolated. To reduce hardware costs, the company wants the branch to connect to the PE device through one CE device with high capability.

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 device connects to vpna and vpnb of the branch through SwitchA and SwitchB.
Figure 1 MCE IPv6 networking

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure OSPF between PE devices to implement interworking between them and configure MP-IBGP to exchange VPN routing information.
  2. Enable basic MPLS capabilities and MPLS LDP on the PE devices to set up LDP LSPs.
  3. Create VPN instances vpna and vpnb on the MCE and PE devices to isolate services.
  4. Set up EBGP peer relationships between PE1 and local CE devices to exchange VPN routes.
  5. Configure routing between MCE and sites and between MCE and PE2 to exchange VPN routes.

Procedure

  1. Configure OSPF on PE1 and PE2 to implement interworking between them.

    # 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
[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 of PE2 is the same as the configuration of PE1.

    After the configuration is complete, PE1 and PE2 can learn the route to Loopback1 of each other.

    Take the display on PE2 as an example:

    [PE2] display ip routing-table
Route Flags: R - relay, D - download to fib, T - to vpn-instance                                   
------------------------------------------------------------------------------
Routing Tables: Public                                                        
         Destinations : 6        Routes : 6   

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface  

        1.1.1.9/32  OSPF    10   1           D   172.1.1.1       Vlanif30  
        2.2.2.9/32  Direct  0    0           D   127.0.0.1       LoopBack1  
      127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0 
      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0 
      172.1.1.0/24  Direct  0    0           D   172.1.1.2       Vlanif30  
      172.1.1.2/32  Direct  0    0           D   127.0.0.1       Vlanif30

  2. Enable basic MPLS capabilities and MPLS LDP on the PE devices to set up LDP LSPs between them.

    # Configure PE1.
    [PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 30
[PE1-Vlanif30] mpls
[PE1-Vlanif30] mpls ldp
[PE1-Vlanif30] quit

    The configuration of PE2 is the same as the configuration of PE1.

    After the configuration is complete, run the display mpls ldp session command on the PE devices. You can see that the MPLS LDP session between the PE devices is in Operational state.

    Take the display on PE2 as an example:

    [PE2] display mpls ldp session

 LDP Session(s) in Public Network
 Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
 A '*' before a session means the session is being deleted.

  3. Enable IPv6. Configure VPN instances on the PE devices. On PE1, bind the VPN instances to the interfaces connected to CE1 and CE2 respectively. On PE2, bind the VPN instances to the interfaces connected to the MCE device.

    # Configure PE1.

  4. Enable IPv6 and configure VPN instances on the MCE device. Bind the vpn instances to the interfaces connected to SwitchA and SwitchB respectively. 

    <HUAWEI> system-view

  5. Set up an MP-IBGP peer relationship between PE1 and PE2. Set up an EBGP peer relationship between PE1 and CE1, and between PE1 and CE2.

    # Configure PE1 to set up an MP-IBGP peer relationship between PE1 and PE2.

    [PE1] bgp 100
[PE1-bgp] router-id 1.1.1.9
[PE1-bgp] peer 2.2.2.9 as-number 100
[PE1-bgp] peer 2.2.2.9 connect-interface loopback 1
[PE1-bgp] ipv6-family vpnv6
[PE1-bgp-af-vpnv6] peer 2.2.2.9 enable
[PE1-bgp-af-vpnv6] quit
[PE1-bgp] quit

    The configuration of PE2 is the same as the configuration of PE1.

    # Configure PE1 to set up an EBGP peer relationship between PE1 and CE1, and between PE1 and CE2.

    [PE1] bgp 100
[PE1-bgp] ipv6-family vpn-instance vpna
[PE1-bgp6-vpna] peer 2001::2 as-number 65410
[PE1-bgp6-vpna] quit
[PE1-bgp] ipv6-family vpn-instance vpnb
[PE1-bgp6-vpnb] peer 2002::2 as-number 65420
[PE1-bgp6-vpnb] quit
[PE1-bgp] quit

    # Configure CE1.

    [CE1] bgp 65410
[CE1-bgp] peer 2001::1 as-number 100
[CE1-bgp] ipv6-family unicast
[CE1-bgp-af-ipv6] peer 2001::1 enable
[CE1-bgp-af-ipv6] import-route direct
[CE1-bgp-af-ipv6] quit
[CE1-bgp] quit

    The configuration of CE2 is the same as the configuration of CE1.

    After the configuration is complete, run the display bgp vpnv6 all peer command on PE1. The command output shows that the PE1 has set up an IBGP peer relationship with PE2 and EBGP peer relationships with CE1 and CE2. All the peer relationships are in Established state.

    [PE1] display bgp vpnv6 all peer

  6. Configure routing between the MCE device and VPN sites.

    # The MCE device directly connects to vpna, and no routing protocol is used in vpna. Configure IPv6 static routes to implement communication between the MCE device and vpna.

    • Configure SwitchA.

      Assign IPv6 address fc00:1::1/64 to the interface connected to vpna.

      <HUAWEI> system-view

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

    # The RIPng protocol runs in vpnb. Configure RIPng process 200 on the MCE device and bind it to vpnb so that routes learned by RIPng are added to the IPv6 routing table of vpnb.

      The preceding information shows that the MCE device has learned the route to vpnb through RIPng. The route to vpnb and the route to vpna (fc00:2::/64) are maintained in different VPN routing tables so that users in the two VPNs are isolated from each other.

  7. Configure OSPFv3 multi-instance between the MCE device and PE2.

    # Configure PE2.
    To configure OSPFv3 multi-instance between the MCE device and PE2, complete the following tasks on PE2:
    • In the OSPFv3 view, import BGP routes and advertise VPN routes of PE1 to the MCE device.
    • In the BGP view, import routes of the OSPFv3 processes and advertise the VPN routes of the MCE device to PE1.

  8. Verify the configuration.

    After the configuration is complete, run the display ipv6 routing-table vpn-instance command on the MCE device to view the routes to the remote CE devices.

    Take the routing table of vpna as an example:

    [MCE] display ipv6 routing-table vpn-instance vpna
Routing Table : vpna
