Example for Configuring Double-Edge Multicast Virtual Scheduling

Example for Configuring Double-Edge Multicast Virtual Scheduling

This section provides an example for configuring double-edge multicast virtual scheduling in the case where two devices are used for user access and multicast forwarding respectively.

Networking Requirements

As shown in Figure 11-5, the user is connected to the network in IPoEoVLAN mode from the GE1/0/0.100 interface of the Device A on a family basis. The Device A authenticates the user through a RADIUS server and allocates bandwidth for the user. The default bandwidth of the user is 2 Mbit/s. Suppose the DSLAM supports IGMP snooping.

The Device A is responsible for user access, and the Device B forwards the multicast traffic. On the basis of the existing network, the Device A is configured to perform multicast virtual scheduling for the user so that the user can watch the multicast programs. If the user subscribes to a CCTV program with a multicast source of 10.0.0.1/24 or a JSTV program with a multicast source of 10.0.0.2/24, without changing the total bandwidth of the user, the Device A adjusts the unicast bandwidth for the user according to the multicast bandwidth. The minimum unicast bandwidth of the user is 1 Mbit/s.

NOTE:

Subinterfaces 1 and interface 2 in this example are GE 1/0/0.100 and GE 2/0/0.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure the IP addresses of the interfaces and the unicast routing protocol.

  2. Set the access mode of the user to IPoEoVLAN to ensure that the user can have access to the Internet normally.

  3. Configure the IGMP and PIM-SM protocols.

  4. Configure the multicast VLAN at the primary interface for user login so that the Device A delivers the multicast data through the multicast VLAN.

  5. Configure the multicast program and the dynamic bandwidth for the program.

  6. Configure the bandwidth reserved for unicast 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 home domain of the user

  • Multicast VLAN ID

  • Address and bandwidth of the multicast program source

  • Bandwidth reserved for unicast

Procedure

  1. Configure the IP addresses of the interfaces and the unicast routing protocol.

    For details, refer to the HUAWEI NetEngine40E Universal Service Router Configuration Guide - IP Services and the HUAWEI NetEngine40E Universal Service Router Configuration Guide - IP Routing.

  2. Configure the user to access network.

    Configure the user to connect to the network in IPoEoVLAN mode through the GE1/0/0.100 interface of the Device A. The user VLAN ID ranges from 1 to 100 and the home domain of the user is "huawei". Configure the Device A to authenticate the user through the RADIUS server. For details, refer to "BRAS Access Configuration" of the HUAWEI NetEngine40E Universal Service Router Configuration Guide - User Access.

  3. Configure the default value of the total bandwidth for the user.

  4. Enable multicast routing and configure the IGMP and PIM protocols.

    NOTE:

    Only the configurations related to the PIM on the Device A are provided here. For multicast routing related to the Internet and the PIM configurations of other devices, refer to HUAWEI NetEngine40E Universal Service Router Configuration Guide - IP Multicast.

    # Enable multicast routing on the Device A.

    [~DeviceA] multicast routing-enable

    # Enable the IGMP protocol on the user-side interface GE1/0/0.100.

    [~DeviceA] interface gigabitethernet 1/0/0.100
    [*DeviceA-GigabitEthernet1/0/0.100] igmp enable
    [*DeviceA-GigabitEthernet1/0/0.100] quit

    # Enable the PIM protocol on the network-side interface GE2/0/0.

    [~DeviceA] interface gigabitethernet 2/0/0
    [*DeviceA-GigabitEthernet2/0/0] pim sm
    [*DeviceA-GigabitEthernet2/0/0] undo shutdown
    [*DeviceA-GigabitEthernet2/0/0] commit
    [~DeviceA-GigabitEthernet2/0/0] return

  5. Configure the Multicast User VLAN Aggregation

    [~DeviceA] interface gigabitethernet 1/0/0
    [*DeviceA-GigabitEthernet1/0/0] igmp enable
    [*DeviceA-GigabitEthernet1/0/0] multicast user-aggregation vlan 1
    [*DeviceA-GigabitEthernet1/0/0] undo shutdown
    [*DeviceA-GigabitEthernet1/0/0] commit
    [~DeviceA-GigabitEthernet1/0/0] return

  6. Configure the multicast program list and bandwidth.

    [~DeviceA] aaa
    [*DeviceA-aaa] multicast-list cctv group-address 10.0.0.1 24
    [*DeviceA-aaa] multicast-list jstv group-address 10.0.0.2 24
    [*DeviceA-aaa] quit
    [*DeviceA] multicastbandwidth
    [*DeviceA-mbandwidth] multicast-list name cctv detect-interval 15 threshold 15
    [*DeviceA-mbandwidth] multicast-list name jstv detect-interval 15 threshold 20
    [*DeviceA-mbandwidth] commit
    [~DeviceA-mbandwidth] return

  7. Configure the bandwidth reserved for unicast and enable multicast virtual scheduling.

    [~DeviceA] aaa
    [*DeviceA-aaa] domain huawei
    [*DeviceA-aaa-domain-huawei] multicast unicast-reservable-bandwidth cir 1024
    [*DeviceA-aaa-domain-huawei] commit
    [~DeviceA-aaa-domain-huawei] return

  8. Disable the device from copying multicast data to forward.

    [~DeviceA] aaa
    [*DeviceA-aaa] domain huawei
    [*DeviceA-aaa-domain-huawei] multicast without-forwarding
    [*DeviceA-aaa-domain-huawei] commit
    [~DeviceA-aaa-domain-huawei] return
