31.5.3 Example of Adaptive Network Configuration

<Structure of this section>

(1) Configuration using IPv6 PIM-SM

This configuration is appropriate in the following cases:

Network environment

The IPv6 unicast routing protocol must run on all routers.
IPv6 PIM-SM is used as the IPv6 multicast routing protocol between the Switches.
Use MLDv1 or MLDv2 to control group administration between groups and the Switch.
One switch is used as the rendezvous point and BSR.

Configuration diagram

The following diagram shows a configuration.

Figure 31-25: Configuration Diagram Using IPv6 PIM-SM

This configuration is appropriate in the following cases:

The number of users sending multicast packets is limited (such as for distribution servers).
Users receiving multicast can specify the address of the MLDv2-compatible sending server.
Broadband multicast communication is used.
Multi-channel multicast communication is used.

Network environment

The IPv6 unicast routing protocol must run on all routers.
IPv6 PIM-SSM is used as the IPv6 multicast routing protocol between the Switches. IPv6 PIM-SSM is extended PIM-SM functionality.
MLDv1 or MLDv2 is used for group administration control between the Switch and a group. (When using MLDv1 or MLDv2(EXCLUDE mode.) SSM must be configured to work together.)
