Right. The RP will infer that it _is_ the RP by virtue of
the multicast traffic that it sees.
But to define the RP on the other routers in the multicast
network you can:
Manually assign an RP address
ip pim rp-address
Use auto-rp
ip pim send-rp-announce
ip pim send-rp-discovery
Use PIM v2 bootstrapping
ip pim rp-candidate
ip pim bsr-candidate
On page 343 of "Developing IP Multicast Networks" by Williamson
there's a note where he says:
"...a router always assumes the duties of RP for a group (subject
to a couple of conditions) any time it receives an incoming (*,G)
Join that contains the address of one of its multicast-enabled
interfaces in this field." (read the book!).
