Example for Configuring Multicast over P2MP TE Tunnels

This section provides an example of how to configure multicast over a point-to-multipoint (P2MP) Traffic Engineering (TE) tunnel.

Networking Requirements

The IP multicast service bearer technology used on the current IP/MPLS backbone network relies on the IP unicast technology. Like IP unicast, IP multicast fails to provide sufficient bandwidth, QoS capabilities, reliability and high real-time performance for multicast services such as IPTV and massively multiplayer online role-playing games (MMORPGs). A P2MP TE tunnel can solve this problem. A P2MP TE tunnel can be configured on a live IP/MPLS backbone network, and supports the P2MP TE FRR function, meeting multicast service requirements.

A P2MP TE tunnel is established on the network shown in Figure 1. PE1 is the tunnel ingress. PE2, and PE3 are leaf nodes, and the tunnel bandwidth is 1000 kbit/s. For the IP address of each node, see Table 1.

Figure 1 Networking for a P2MP TE tunnel

Interfaces 1, 2, 3, and 4 in this example represent GE 0/1/0, GE 0/1/8, and GE 0/1/16, respectively.

Precautions

When you configure multicast, enable IGMP on the PE interface connected to multicast data receivers.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Assign an IP address to each interface and configure a loopback interface address as an LSR ID on each node.

  2. Configure Intermediate System to Intermediate System (IS-IS) to advertise the route to each network segment of each interface and the host route to each loopback interface address that is an LSR ID.

  3. Enable MPLS, MPLS TE, and MPLS Resource Reservation Protocol (RSVP) globally on each node and constraint shortest path first (CSPF) on the ingress to enable all nodes to have MPLS forwarding capabilities.

  4. Enable the IS-IS TE capability to ensure that MPLS TE can advertise information about link status.

  5. Enable the MPLS TE capability on the interfaces of each node, and configure link attributes for the interfaces so that the interfaces can send RSVP signaling packets.

  6. Configure explicit paths and a leaf list on the ingress PE1 to specify the leaf nodes on the P2MP TE tunnel.

  7. Configure a P2MP TE tunnel interface on PE1 to ensure that the ingress establishes a P2MP TE tunnel based on all configuration information on the interface.

  8. Enable multicast on the device connected to the multicast source, ingress, and egresses.

  9. On PE1, direct multicast traffic to the P2MP TE tunnel. On PE2 and PE3, direct multicast traffic out of the P2MP TE tunnel.

Data Preparation

To complete the configuration, you need the following data:

  • IP addresses of all interfaces shown in Figure 1

  • IS-IS (used as an IGP protocol), IS-IS process ID (1), IS-IS system ID of each node (obtained by translating the IP address of loopback1 of each node), and IS-IS level (Level-2)

  • MPLS LSR ID of each node using the corresponding loopback interface address

  • Maximum reservable bandwidth (10000 kbit/s) of the outbound interface along the path and BC0 bandwidth (10000 kbit/s)

  • Name of an explicit path used by each leaf node (tope1, tope2, and tope3), name of the leaf list (iptv1), and addresses of each leaf node (MPLS LSR ID of each leaf node)

  • Tunnel interface number (Tunnel 10), tunnel ID (100), loopback interface address used as the IP address of the tunnel interface, and tunnel bandwidth (1000 kbit/s)

Procedure

  1. Configure IP addresses for the interfaces.

    Configure IP addresses for the interfaces according to Figure 1, and create a loopback interface on each node. For configuration details, see Configuration Files in this section.

  2. Configure IS-IS to advertise the route to each network segment of each interface and to advertise the host route to each LSR ID.

    Configure IS-IS on each node to allow the nodes to communicate at the network layer. For configuration details, see Configuration Files in this section.

  3. Enable MPLS, MPLS TE, and MPLS RSVP globally on each node and CSPF on the ingress.
