Example for Configuring Multicast Control
This section provides several examples to illustrate how to configure controllable multicast based on a typical controllable multicast networking.
Networking Requirement
Multicast control is required to control the multicast rights of users in different domains.
As shown in Figure 1, three multicast sources, S1, S2, and S3, in the PIM-SM domain send packets with addresses 225.1.1.1, 226.1.1.1, and 227.1.1.1. Users access the multicast network through the router. The requirements are as follows: Users in domain isp1 can join multicast groups 225.1.1.1 and 226.1.1.1 only; users in domain isp2 can join multicast groups 226.1.1.1 and 227.1.1.1 only.
This example describes how to configure multicast control on an IPv4 network. Configurations on an IPv6 network are the same, and are not mentioned here.
The BRAS uses GE 0/1/0 to communicate with the access network and uses GE 0/1/1, GE 0/1/2, and GE 0/1/3 to communicate with PIM-SM devices.
Configuration Roadmap
The configuration roadmap is as follows:
Configure the IP addresses of the interfaces and the unicast routing protocol to implement IP connectivity.
Configure the access service so that users can go online.
Configure IGMP and PIM-SM to implement uncontrollable multicast.
Configure the controllable multicast feature and enable controllable multicast on interfaces.
Verify the configuration.
Data Preparation
- Maximum number of multicast programs that a user is allowed to access at a time (the value is 2)
Procedure
- Configure the IP address of the interface and the unicast routing protocol.
For details, refer to the HUAWEI NetEngine 8000 F SeriesRouterConfiguration Guide - IP Services and the HUAWEI NetEngine 8000 F SeriesRouterConfiguration Guide - IP Routing.
- Configure the access service.
For details, refer to the HUAWEI NetEngine 8000 F SeriesRouterConfiguration Guide - User Access.
- Configure the IGMP and the PIM-SM protocols.
For details, see IGMP Configuration and PIM Configuration>Configuring PIM-SM.
- Configure multicast control.
