Example for Configuring Multicast Functions in Daisy-Chain Networking

This section provides an example for configuring multicast functions in daisy-chain networking. Deploying multicast services in daisy-chain networking prevents the transmission of duplicate multicast data on a MAN ring, thereby saving network bandwidth.

Networking Requirements

Figure 1 shows a typical multicast networking. SR is a master service termination point and BSR is a backup SR. Protocol Independent Multicast - Sparse Mode (PIM-SM) is configured on the network side of SR to enable SR to receive multicast data and IGMP is configured on the user side of SR to manage multicast group members. On the MAN, UPEs and NPEs transparently transmit user requests and multicast traffic over PWs. NPE1 needs to set up a PW with each UPE. (NPE2 backs up NPE1.)

After multicast traffic reaches NPEs, it must be replicated on the leaf network. If devices attached to each UPE require this multicast traffic, NPE1 must replicate a copy of multicast traffic for each PW connecting a UPE.

Figure 1 Networking diagram for deploying multicast services in the common VPLS networking

A PW is a virtual tunnel and actually, traffic is transmitted along the MAN ring. Use the Figure 1 to illustrate the actual traffic forwarding path (traffic forwarding for NPE2 is not provided):
  • The traffic forwarding path corresponding to the PW from NPE1 to UPE1 is NPE1 -> UPE1.
  • The traffic forwarding path corresponding to the PW from NPE1 to UPE2 is NPE1 -> UPE1 -> UPE2.
  • The traffic forwarding path corresponding to the PW from NPE1 to UPE3 is NPE1 -> UPE1 -> UPE2 -> UPE3.
Therefore, one multicast packet is transmitted several times over the links between NPE1 and UPE1 and between UPE1 and UPE2. If there are more nodes on the MAN ring, the multicast packet is transmitted multiple times. This greatly wastes network bandwidth because multicast traffic generally uses a large amount of bandwidth.

The daisy-chain networking can solve this problem. Figure 2 shows the daisy-chain networking.

In this networking, a UPE sets up a PW with only an adjacent UPE or NPE. As a result, on the entire MAN ring, a chain composed of VPLS PWs is formed and only one copy of data is transmitted along the chain. Such a chain is called a daisy chain. On a daisy chain, an NPE no long needs to set up PWs with all UPEs, preventing duplicate multicast traffic transmission.

The daisy-chain networking does not apply to unicast services for the following reasons:
  • Unicast services are transmitted over point-to-point connections and therefore will not be transmitted repeatedly over a PW.
  • The daisy-chain networking makes configuration and reliability protection more complex.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure basic MPLS functions and L2VPN functions on each device to ensure that multicast services run properly on the L2VPN.

  2. Create the VSI btv on each device; create a PW between an NPE and its adjacent UPE and a Spoke PW between every two UPEs so that virtual tunnels exist between adjacent devices.

  3. Configure IGMP snooping and IGMP Snooping proxy for the VSI to manage the forwarding of multicast data packets. An IGMP Snooping Proxy substitutes for both upstream and downstream devices to send multicast protocol packets, which implements on-demand multicast data forwarding on the Layer 2 VPLS network and saves network bandwidth.

  4. Add the sub-interface bound to the VSI on each device to a multicast group statically so that users attached to each device can steadily receive multicast data for the multicast groups, avoiding network attacks.

Data Preparation

To complete the configuration, you need the following data:

  • IP addresses of the interfaces and loopback address of each device (for details, see Figure 2)

  • IP routing protocol (IS-IS is used in this example and the process ID is 1)

  • MPLS Label Switch Router (LSR) ID of each device (consistent with loopback address of each device)

  • VSI name (btv is used in this example) used when setting up a PW between every two adjacent devices

  • Sub-interface bound to the VSI on each UPE and VLAN to which users belong (GE0/1/2.1 and VLAN 10 are used in this example)

  • Address of the multicast group to which users attached to UPE1, UPE2, and UPE3 are to be statically added (225.0.0.1 is used in this example)

Procedure

  1. Configure interface IP addresses, loopback addresses, and IS-IS on all NPEs and UPEs.

  3. Verify the MPLS configuration.

    After the preceding configurations are complete, run the display mpls ldp session command on each device. The command output shows that the status of the LDP session between every two adjacent devices is Operational.

    The following example uses the command output on UPE2.

    [~UPE2] display mpls ldp session

 An asterisk (*) before a session means the session is being deleted.

  9. Verify the configuration.

    After the preceding configurations are complete, run the display igmp-snooping port-info command on UPE1, UPE2, and UPE3 to check static member port information of the VSI. The following example uses the command output on UPE2.
