Peng,
Auto-RP requires that the candidates announce on dense-mode groups
224.0.1.39, and that the mapping agent announce the RP on dense mode group
224.0.1.40. You can either use sparse-dense mode on the interfaces, or you
can enter ip pim auto-rp listener in global config of each router. The
latter command permits dense mode on sparse-configured interfaces only for
the auto-rp groups.
HTH,
