Summary:The invention discloses a method for realizing PIM (Protocol Independent Multicast) in a VRRP (Virtual Router Redundancy Protocol) network environment. A virtual IP (Internet Protocol) address is carried when a PIM Hello message is transmitted to an interface for enabling the VRRP; when the PIM Hello message is received, the virtual IP address of the VRRP is used for establishing a PIM neighbor, so that unicast and multicast services can be simultaneously used as a host and a backup in the VRRP network environment. Meanwhile, the virtual IP address of the VRRP is completely compatible with a current RFC (Request for Comments) protocol, and so that the problem that the VRRP and the multicast cannot be deployed simultaneously at present is solved. The invention also discloses a device for realizing the PIM multicast in the VRRP network environment. The device comprises a transmitting module and a receiving module, wherein the transmitting module is used for transmitting the PIM Hello message carrying the virtua
