Network requirements
As shown in
•
IPv6 multicast routing and IPv6 PIM-DM are enabled on Switch A and Switch C.
•
Switch B does not support IPv6 multicast.
•
OSPFv3 is running on Switch A, Switch B, and Switch C.
Configure the switches so that the receiver can receive the IPv6 multicast data from the source.
