What does it mean for a neighbor to have an RPF entry of 0.0.0.0? Also what does it mean for a neighbor to have an RPF entry of 224.0.0.0?

For an (S,G) entry an RPF entry of 0.0.0.0 means that the source of the mutlicast stream for that group is on a subnet attached to this router.
For a (*, G) entry an RPF entry of 0.0.0.0 means you are on the RP (Rendevous Point) for that group.
Not sure about 224.0.0.0 ? - could you provide an example ?

Please see attached. I found this on a practice exam.
Another example: http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/pimrpfvr.html - look at the show ip mroute 232.6.6.6 command about halfway down.
