Hi
It will work for sure if You configure ip of rp on rp itself.
You don't have to configure ip pim rp-address on RP if You have the
following:
(assume that R2 is RP)
Mult.Sender-------R1----(et0)R2(et1)----R3-----Mult Receiver
on R1 & R3:
ip pim rp-address (ip of et0 on R2) i.e. ip of closest interface to Sender !
If You put any other ip address of R2 (f.e et1, or loopbacks, or whatever)
it will NOT work
IP of RP must be ip of interface where mult stream comes in.
Again if You put command ip pim rp-address on RP itself it will always work.
BTW, auto-rp is working fine.
I didn't find any explanations on CCO or in books, but I tested it many
times.

Subject: RE: Multicasting - Sparse Mode Static RP
Since I started this thread off I feel obligated to try to un-muddy the
waters a little. Using PIM Sparse Mode and choosing to statically
configure the RP on all the routers it seemed that I couldn't get it to
work unless I configured the "ip pim rp-address" on the RP itself.
Well, I was having another (DLSW) problem and once it was fixed it no
longer seemed to require the manually configured address on the RP
itself. I would have to say it didn't seem to need it. However, as
someone said, configuring it on the RP didn't seem to do any harm
either. Sorry if I got anyone started down the wrong track!
Thanks,
George

Georg is correct. Manual configuration on every router is necessary is
sparse mode.
