After many try of the proposed solution and some variation, routing
doesn't work if I don't activate PIM-SM too.
But I search to route multicast stream with only, a static routing
beetween router 2 and 3, IGMP beetween router 1 and 2 and IGMP
beetween 3 and 4.
Thanks ,
Fabien

effectively , I write my case with this syntax error.
