The group 266.2.2.2 multicast packets don't reach R3.
I also tried to change the OSPF network type to point-to-multipoint on
all the nodes, it didn't change anything. Do you have any other ideas?
I can't do any other experiment now as it is 1.30AM.
Thanks for your support! Together we can defeat Bidirectional PIM! :)
