There's a superb blog post on troubleshooting RPF failure to be found on one
of the big training vendor's websites...

Subject: How to determine using Ip mroute for RPF CHeck or not ?
guys,
My real lab just in a couple of weeks forward and I still don't know how to
verify when I have to us ip mroute static for multicast or not.
How can I debug when there is an rpf failure ? How to verify it ?
The mroute static is used for the source to the client only right ? For
multicast we just have to concern about the route from source to client, not
client to source ?
And when to test a multicast source connection with a command interfce ip
igmp join group, is that interface have to be a part of the mulcticast mode
(sparse-mode, dense-mode, sparse-dense mode)?
Please correct me if I'm wrong
Thanks a lot guys
