Embodiments of the present invention provide a multicast group allocation method, a centralized control point, and a multicast router. The multicast group allocation method in the embodiments of the present invention comprises: a centralized control point determines a correspondence between at least two multicast groups and at least two RPs according to information about the at least two multicast groups and information about the at least two RPs in a rendezvous point set, wherein in the correspondence between the at least two multicast groups and the at least two RPs, the quantities of multicast groups corresponding to each RP are same; the centralized control point averagely allocates the at least two multicast groups to the at least two RPs according to the correspondence between the at least two multicast groups and the at least two RPs; and the centralized control point diffuses the correspondence between the at least two multicast groups and the at least two RPs to all multicast routers in a PIM network. The embodiments of the present invention can ensure load balance of different RPs in at least two RPs. |
