Example for Configuring Inter-AS IPv6 NG MVPN Option B

In this example, communication between VPNs spans multiple ASs on the backbone network, and ASBRs advertise labeled VPN-IPv4 routes through MP-EBGP.

Networking Requirements

As shown in Figure 1, CE1 and CE2 belong to different VPNs. Communication between the VPNs spans two ASs: AS 100 and AS 200. VPN instances do not need to be created on each ASBR. Instead, each ASBR only needs to receive VPNv6 routes and transmit the routes to the peer ASBR. The MP-IBGP peer relationship needs to be established between each pair of PE and ASBR, and the MP-EBGP peer relationship needs to be established between the ASBRs.

Precautions

When configuring inter-AS IPv6 NG MVPN Option B, note the following:

  • The MP-EBGP peer relationship needs to be established between ASBRs in different ASs. The MP-IBGP peer relationship needs to be established between the PE and ASBR in the same AS.

  • ASBRs do not filter received VPNv6 routes based on VPN targets.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Run an IGP in each AS to implement communication between nodes in the same AS. Establish an MPLS LDP LSP between the ASBR and PE in the same AS.

  2. Configure the MP-EBGP peer relationship between ASBRs in different ASs. Configure the MP-IBGP peer relationship between the PE and ASBR in the same AS.

  3. Configure a VPN instance on each PE and bind the interface that connects a PE to a CE to the VPN instance on that PE.

  4. Enable MPLS on the ASBR interfaces connected to each other. Establish an MP-EBGP peer relationship between ASBRs and configure ASBRs not to filter VPNv6 routes based on VPN targets.

  5. Configure a P2MP LSP to carry multicast traffic.

  6. Configure PIM.

Data Preparation

To complete the configuration, you need the following data:

  • MPLS LSR IDs of the PEs and ASBRs (1.1.1.1, 1.1.1.2, 1.1.1.3, and 1.1.1.4)

  • Name (ngv6), RD (100:1 and 200:1), and export and import VPN targets (1:1) of the VPN instance on each PE

Procedure

  1. Configure an IGP on the MPLS backbone networks of AS100 and AS200, so that nodes on each MPLS backbone network can communicate with each other.

    This example uses OSPF. For configuration details, see Configuration Files in this example.

  2. Configure IS-IS for communication between PEs and CEs. For configuration details, see Configuration Files in this example.
  3. Configure basic MPLS functions and MPLS LDP on the MPLS backbone networks of AS100 and AS200 to establish LDP LSPs.

    # Configure PE1.

    [~PE1] mpls lsr-id 1.1.1.1

    The procedure for configuring PE2 is similar to the procedure for configuring PE1. For configuration details, see Configuration Files in this example.

    # Configure ASBR1.

[~ASBR1-GigabitEthernet0/1/4] quit

    The procedure for configuring ASBR2 is similar to the procedure for configuring ASBR1. For configuration details, see Configuration Files in this example.

    After the configurations are complete, LDP peer relationships are set up between the PE and ASBR in each AS and between ASBRs. Run the display mpls ldp session command on each router. The command output shows that Session State is Operational. The following example uses the command output on PE1.

    <PE1> display mpls ldp session
 LDP Session(s) in Public Network
 Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
 An asterisk (*) before a session means the session is being deleted.

  4. Configure an automatic mLDP P2MP LSP on PEs and ASBRs.

    # Configure PE1.

[~ASBR1-mpls-ldp] quit

    The procedure for configuring ASBR2 is similar to the procedure for configuring ASBR1. For configuration details, see Configuration Files in this example.

  5. Configure the MP-IBGP peer relationship between the PE and ASBR in the same AS.

    # Configure PE1.

    [~PE1] bgp 100
[*PE1-bgp] peer 1.1.1.2 as-number 100
[*PE1-bgp] peer 1.1.1.2 connect-interface loopback 0

[~PE1-bgp] quit

    # Configure ASBR1.

    [~ASBR1] bgp 100

[*ASBR1-bgp-af-vpnv6] commit
[~ASBR1-bgp-af-vpnv6] quit
[~ASBR1-bgp] quit

    The procedure for configuring AS200 is similar to the procedure for configuring AS100. For configuration details, see Configuration Files in this example.

    After the configuration is complete, run the display bgp vpnv4 all peer command on the PE or ASBR. The command output shows that the MP-IBGP peer relationship between the PE and ASBR in the same AS or between ASBRs is in the Established state. The command output on PE1 is used as an example.

    <PE1> display bgp vpnv6 all peer
