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

This example describes how to configure inter-AS seamless MPLS NG MVPN in Option B mode to implement E2E service connectivity, when the devices are in different ASs.

Networking Requirements

As shown in the Figure 1, the PEs, ABR and ASBRs are in different ASs. To implement the connectivity between PEs and provides multicast service with MVPN, you can implement the inter-AS seamless MPLS NG MVPN.

Figure 1 Inter-AS Seamless MPLS NG MVPN Option B

In this example, interface 1 and interface 2 represent GE 0/1/1 and GE 0/1/2, respectively.


Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IGP protocols at each network to implement network connectivity at each network.

  2. Set up an MPLS LDP LSP in each network.

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

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

  5. Configure ABR as an RR.

  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 BGP 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 the devices (1.1.1.1, 2.2.2.2, 3.3.3.3, 4.4.4.4, and 5.5.5.5)

  • Route policy configured on each device (policy1)

Procedure

  1. Configure an IP address for each interface.

    Assign an IP address and its mask to every physical interface; configure a loopback interface address as an LSR ID on every device shown in Figure 1; configure OSPF and IS-IS to advertise the route to the network segment of each interface and a host route to each loopback interface address (LSR ID). For configuration details, see Configuration Files in this section.

  2. Enable MPLS and LDP globally on each device.

  9. Verify the configuration.

    After the configurations are complete, run the display ip routing-table command on PE1 or PE2 to display the routes to each other's loopback address.

    The following example uses the command output on PE1:

    <PE1> display ip routing-table

    Run the display mpls lsp command on PE1 or PE2 to display the LSP information.

    The following example uses the command output on PE1:

    <PE1> display mpls lsp
Flag after Out IF: (I) - RLFA Iterated LSP, (I*) - Normal and RLFA Iterated LSP

5.5.5.5/32         NULL/32835      -/-

    Run the ping lsp command on PE1 or PE2 to check the connectivity of BGP LSP.

    The following example uses the command output on PE1:

    <PE1> ping lsp bgp 5.5.5.5 32
  LSP PING FEC: IPV4 PREFIX 5.5.5.5/32/ : 100  data bytes, press CTRL_C to break
