Example for Configuring IPv6 NG MVPN Option B in an Inter-AS Seamless MPLS Scenario

When devices are deployed in different ASs, you can deploy IPv6 NG MVPN in an inter-AS seamless MPLS scenario to implement end-to-end service interworking.

Networking Requirements

As shown in Figure 1, the PEs, ABR, and ASBRs are in different ASs. To allow the PEs to communicate and provide VPN services, you can configure IPv6 NG MVPN in an inter-AS seamless MPLS scenario.

Figure 1 Networking for IPv6 NG MVPN in an inter-AS seamless MPLS scenario

Interfaces 1 through 4 in this example represent GE 0/1/1, GE 0/1/2, GE 0/1/3, and GE 0/1/4, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP protocol on each network for connectivity.

  2. Configure MPLS and MPLS LDP and establish MPLS LSPs on each network.

  3. Establish IBGP peer relationships in each AS and enable devices to exchange labeled routes.

  4. Establish an EBGP peer relationship between ASBRs and enable these devices to exchange labeled routes across ASs.

  5. Configure the ABR as an RR to help PE1 and ASBR1 obtain the route destined for each other's loopback interface.

  6. Configure a routing policy to control label distribution for a BGP LSP to be established on each device. The egress of the BGP LSP to be established needs to assign an MPLS label to the route advertised to an upstream node. If a transit node receives a labeled IPv4 route from downstream, the downstream node must re-assign an MPLS label to the transit node.

  7. Configure peers.

  8. Configure a P2MP LSP to carry multicast traffic.

Data Preparation

To complete the configuration, you need the following data:

  • MPLS LSR IDs of devices (1.1.1.1, 1.1.1.2, 1.1.1.3, 1.1.1.4, and 1.1.1.5)

  • Name of a routing policy (policy1)

Procedure

  1. Configure IGPs on the MPLS backbone networks in AS100 and AS200, so that the PE and ASBR on the same MPLS backbone network can communicate. OSPF is used between PE1 and the ABR; IS-IS is used between the ABR and ASBR1, between ASBR2 and PE2, and between PEs and CEs; a static route is configured between ASBRs. For configuration details, see Configuration Files in this example.
  2. Enable MPLS and LDP globally on each device and configure LDP LSPs.

    Run the display pim ipv6 routing-table command on a PE to check the PIM routing table.
