Example for Configuring Single-Edge Multicast Virtual Scheduling

This section provides an example for configuring single-edge multicast virtual scheduling in the case where a single device is used for both user access and multicast traffic forwarding.

Networking Requirements

This is an example of normal single-edge networking. In the networking of MPLS multicast, the multicast without-forwarding command must be run to disable the devices from copying multicast data.
In the networking of MPLS multicast, the IGMP and PIM protocols can be configured only on VE interfaces. For details, see "IGMP Configuration" and "PIM-SM Configuration" in HUAWEI NetEngine 8000 F Series Router Configuration Guide - IP Multicast.

As shown in Figure 1, the family user accesses the Internet in IPoEoVLAN mode through GE 0/1/0.100 on the router. The router authenticates the user through a RADIUS server and allocates bandwidth for the user. The default bandwidth of the user is 2 Mbit/s. The DSLAM supports IGMP snooping.

The router implements both user access and multicast traffic forwarding. On the basis of the existing network, the router is configured to perform multicast virtual scheduling for the user so that the user can watch the multicast programs normally. If the user subscribes to a CCTV program with the multicast group 239.0.0.1/24 or a JSTV program with the multicast group 239.0.0.2/24, the router adjusts the unicast bandwidth for the user according to the multicast bandwidth, with the total bandwidth of the user remaining unchanged. The minimum unicast bandwidth of the user is 1 Mbit/s.

In this example, sub-interface 1 and interface 2 represent GE 0/1/0.100 and GE 0/1/8, respectively.

Figure 1 Configuring single-edge multicast virtual scheduling

Configuration Roadmap

The configuration roadmap is as follows:

Configure IP addresses for interfaces and a unicast routing protocol to implement IP connectivity.
Configure the IPoEoVLAN access type to allow the user to access the Internet.
Configure IGMP and PIM-SM.
Configure a multicast VLAN on the main user access interface so that the router can deliver multicast data through the multicast VLAN.
Configure a multicast program list and the parameters for multicast program bandwidth.
Configure the bandwidth reserved for unicast traffic and enable multicast virtual scheduling.

Data Preparation

To complete the configuration, you need the following data:

Number of the interface from which the user is connected to the network, VLAN ID on the user side, and homing domain of the user
Multicast VLAN ID
Addresses and bandwidth of the multicast programs
Bandwidth reserved for unicast traffic

Procedure

Configure an IP address for each interface and a unicast routing protocol.
For details, see HUAWEI NetEngine 8000 F SeriesRouter Configuration Guide - IP Services and HUAWEI NetEngine 8000 F SeriesRouter Configuration Guide - IP Routing.
Configure user access.
Configure the user to connect to the network in IPoEoVLAN mode through GE 0/1/0.100 of the router. The user VLAN ID ranges from 1 to 100, and the homing domain of the user is "huawei". Configure the router to authenticate the user through the RADIUS server. For details, see "Configuring BRAS Access" in HUAWEI NetEngine 8000 F SeriesRouter Configuration Guide - User Access.

Configure the default total bandwidth of the user.
