It says: Configure R5, R6 and R7 ethernet interfaces to support both PIM sparse and Dense mode streams. Configure the link between R7 and R8 as well as R8 Ethernet to support PIPM Sparse-Dense.
R6 fa0/0 pim sparse-dense R7 fa0/0 pim sparse R7 s0/0/0 pim sparse R8 s0/0/0 ip pim sparse dense So the first requirement it doesn't satisfy because both interfaces on R7 (R5 is correct as well as R6) are set to sparse. The second requirement also is not satisfied because of R7 s0/0/0 being set to sparse. R8 ethernet is not set at all in the config example. I just wonder if it's intentionally set like that so R8 can't reach R5 (RP), and R7 can because R8 sets R7 statically as it's RP (override). That would match with the example output, where R8 has no announced RP but does have a static RP. But i don't see why setting an interface to sparse-dense mixed with sparse should prevent any multicast flowing?
