Zhou,
the problem here is that in PIM dense, sparse ou sparse-dense and for any
multicast group, if an interface exist in multicast "input list interfaces"
it can never exist in the multicast "output list interface (olist)" for the
same group. so the solution is to use differents subinterface and it may
work. don't care, I belive this scenarion can never be in LAB exam.

I do a lab for auto-rp and sparse-dense over frame multipoint question.
according TCP/IP volume 2 ,r1,r2,r3 in same subnet,r2 is hub,r1 and r3 is
spoke ,the question is r1 and r3 cann't each other ping it's group
address,r1 and r3 can ping r2's group address.thank you for any advice!
