Example for Configuring QinQ VLAN Tag Termination Sub-Interfaces to Statically Join Multicast Groups

Networking Requirements

On the network shown in Figure 1, configure a QinQ VLAN tag termination sub-interface on PE1 to statically join multicast groups, to make the Receiver receive multicast data sent from the Source.

Figure 1 Configuring QinQ VLAN tag termination sub-interfaces to statically join multicast groups

Interfaces 1 through 3 and sub-interface 2.1 in this example represent GE 0/1/0, GE 0/1/8, GE 0/1/16, and GE 0/1/8.1, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure Open Shortest Path First (OSPF) on the backbone network to implement interworking between PEs.

  2. Configure the basic Multiprotocol Label Switching (MPLS) functions and MPLS Label Distribution Protocol (LDP) on the PEs and establish the MPLS Label Switched Paths (LSPs) between the PEs.

  3. Configure the VPN instance on the PE and bind VPN instance with the interface to Source and the interface to Receiver.

  4. Configure Multiprotocol Internal Border Gateway Protocol (MP-IBGP) to exchange the VPN routing information between the PEs.

  5. Configure QinQ VLAN tag termination sub-interfaces to statically join multicast groups.

Data Preparation

To configure QinQ VLAN tag termination sub-interfaces to statically join multicast groups, you need the following data:

  • PE's MPLS LSR-ID: 1.1.1.9; P's MPLS LSR-ID: 2.2.2.9,3.3.3.9

  • VPN instance name: vpna; RDs: 100:1 and 100:2; VPN-Target: 111:1

  • VLAN ID in an outer VLAN tag of the QinQ VLAN tag termination sub-interface: 1; VLAN ID in an inner VLAN tag of the QinQ VLAN tag termination sub-interface: 1 or 2

Procedure

  1. Configure basic BGP/MPLS IP VPN.

    The specific configuration procedures are omitted here.

  2. Configure a VPN instance on each PE, configure a QinQ VLAN tag termination sub-interface, and bind the interface to the VPN instance.

    # Configure PE1.

    # Configure a VPN instance.

[*PE2-GigabitEthernet0/1/0] ip address 10.3.1.2 24
[*PE2-GigabitEthernet0/1/0] commit
[~PE2-GigabitEthernet0/1/0] quit

  3. Add the route of the Source and the route of the Receiver to VPN routing-table.

    # Configure PE1.

    [*PE1] bgp 100
[*PE1-bgp] ipv4-family vpn-instance vpna
[*PE1-bgp-vpna] import-route direct
[*PE1-bgp-vpna] quit
[*PE1-bgp] quit
[*PE1] commit

    # Configure PE2.

    [*PE2] bgp 100
[*PE2-bgp] ipv4-family vpn-instance vpna
[*PE2-bgp-vpna] import-route direct
[*PE2-bgp-vpna] quit
[*PE2-bgp] quit
[*PE2] commit

    After the configuration above, run the display ip routing-table vpn-instance command on PE1. The route of the Source and the route of the Receiver are added to VPN routing-table.

    [~PE1] display ip routing-table vpn-instance vpna
Route Flags: R - relay, D - download to fib, T - to vpn-instance, B - black hole route
