8.3.6 Example for applying multicast on ring network
Networking requirements
Configure IGMP ring forwarding on single Ethernet ring to make multicast service more
stable and prevent multicast service from being disrupted by link failure.
As shown in Figure 8-6, GE 1/1/1 and GE 1/1/2 on Switch A, GE 1/1/1 and GE 1/1/2 on
Switch B, GE 1/1/1 and GE 1/1/2 on Switch C form a physical ring. Multicast traffic is input
from GE 1/1/1 on Switch B. The customer demands multicast traffic through GE 1/1/3 and
GE 1/1/4 on Switch C. By doing this, it will not affect user's on-demand multicast stream
whichever link fails in the Switch.
When using single Ethernet ring to provide multicast services, you can adopt IGMP MVR or
IGMP Snooping to receive the multicast traffic.
The following example shows that STP provides ring network detection and IGMP Snooping
provides multicast function.
