Multicast over FR

[ikizoo4]

Hi

I like to configure sparse-dense mode ( when RP is failed, let dense mode work) over FR hub and stroke(no subinterface allowed), router A is hub and router B,C are spokes, by configuring router A as BSR and using PIMv2, the RP mapping issue is cleared, but router A has RPF issue, can't forward multicast packet to spokes, because FR is not available multicast nature on multipoint FR interface(NBMA), how can i fix this problem?

thanks

While trying to transfer multicast packets to spokes, what error message do u receive?.Send me the debug o/p from the hub router.If u send it, it will be really useful for me to trace out the problem. Also, let me know what router's u use as hub and spoke
