As in scenario 2 is working I dont think It could be a MSDP problem. But the
problem appears when you change the ubication of the source stream server
from r2 lan network to r1 lan network?
Could you paste your configs? also, in which interfaces in your topology are
configured as sparse mode?
maybe it could be a rpf chek issue.
