Configuring IPv4 Static Multicast

To allow IPv4 BAS users to receive the traffic of specific multicast groups without sending IGMP join messages, configure static multicast.

Usage Scenario

Configure static multicast when a program (such as an advertisement program) needs to be pushed to users, delivered to users' STBs before users join the program, or delivered to Layer 2 devices before users join the program. Static multicast helps shorten the program switching duration.

Pre-configuration Tasks

Before configuring static multicast, complete the tasks shown in Figure 1. For configuration details, see Table 1.

Figure 1 Pre-configuration tasks for static multicast configurations

	Configure an IPv4 Address Pool to Assign IP Addresses to Online Users.
	Configure Authentication, Authorization and Accounting (AAA) schemes.
	Configure a Domain to Manage Online Users.
	Configure the PPPoE or IPoE access mode. Configure the PPPoE access mode. Configure the IPoE access mode.

Procedure

Configure a multicast program list
1. Run system-view
  The system view is displayed.
2. Run aaa
  The AAA view is displayed.
3. Run multicast-list list-name [ index list-index ] [ source-address source-address ] group-address group-address [ vpn-instance vpn-instance-name ]
  An IPv4 multicast program list is created.
Configure a multicast profile
1. Run system-view
  The system view is displayed.
2. Run aaa
  The AAA view is displayed.
3. Run multicast-profile profile-name
  An IPv4 multicast profile is configured, and the profile view is displayed.
4. Run multicast-list { name list-name | list-index start-index [ end-index ] } [ static ]
  The IPv4 multicast program list is bound to the IPv4 multicast profile.
5. Run authentication
  Authentication is enabled for IPv4 multicast users.
Bind the multicast profile to the AAA domain.
1. Run system-view
  The system view is displayed.
2. Run aaa
  The AAA view is displayed.
3. Run domain domain-name
  The AAA domain view is displayed.
4. Run multicast-profile profile-name
  The IPv4 multicast profile is bound to the AAA domain.
After a multicast profile is bound to a domain, users in this domain are allowed to access the programs defined in the multicast program list that is bound to the multicast profile. One domain can use only one multicast profile. If multiple multicast profiles are bound to a domain, the latest binding takes effect.

Checking the Configurations

Run the display multicast-profile command to check information about a specified or all multicast profiles.

Run the display multicast-list command to check information about a specified or all multicast program lists.
