Section 4.5.6 says:
bool JoinDesired(*,G) { if (immediate_olist(*,G) != NULL OR (JoinDesired(*,*,RP(G)) AND AssertWinner(*, G, RPF_interface(RP(G))) != NULL)) return TRUE else return FALSE } JoinDesired(*,G) is true when the router has forwarding state that would cause it to forward traffic for G using shared tree state. Note that although JoinDesired is true, the router's sending of a Join(*,G) message may be suppressed by another router sending a Join(*,G) onto the upstream interface.
Notes:
When would immediate_olist(*,G) be NULL and forwarding state exist?
