Abstract
A method for communication between IP devices is provided. The method includes: receiving a dynamic routing protocol control packet sent by each of actual physical routers in a virtual router; obtaining a virtual IP address according to the dynamic routing protocol control packet; and using the virtual IP address as a next hop address and sending information to be sent to an external network to the virtual router. Further, a system and a router for communication between IP devices are also provided. Through the technical solutions of the present invention, when the master router is transited, the conversion of the internal dynamic routing protocol matches with the transiting of the master router performed by the virtual. Thus, it is ensured that the transited master router can receive the information sent by the internal router in a short time.
