It is possible to describe the performance of the router device that transmits the message (here, the master router device 101). For example, if the performance such as data processing capacity is high enough to operate as a master router, enter a large number. If the performance is low and operation as a master router should be avoided as much as possible, enter a small number. It will be described.
- the router 103 Upon receipt of the message, the router 103 sets its own priority based on the information described in the preference (Preference) field 63 and the information described in the priority (Pri or ity) field 53. The degree may be calculated.

That is, when operating as the backup file overnight device 102, the virtual file overnight message is not transmitted, and steps S16 and S17 are omitted. As a result, an increase in network traffic can be suppressed.
- the router device 10 transmits the virtual router information message regardless of whether it is the master device 101 or the backup device 102.
- the type (Type) field 51 is set to '3' (this is an information message).
- (Infinity) means that the conventional virtual router redundancy protocol can be used. Collaborate with Kor (VRRP).
- step S17 after transmitting the virtual route information message (step S17), the process returns to step S16, but after step S17, step S11 is performed again. You may make it implement.
- the configuration is such that virtual router information is obtained from an existing router device.
- the present invention is not limited to this. It is also possible to adopt a configuration in which the information is obtained over a night.
- the existing router device on the network is not the router device according to the present invention, but a newly connected router device. As long as is the router device of the present invention, the same effect can be obtained.
- the router device 10 when newly connecting to a network, dynamically acquires virtual router information from an existing virtual router system and performs necessary processing for its own virtual router processing. Data can be set. This makes it possible to automatically set up a virtual router in a short period of time, which has been done manually in the past, thus reducing the load on the administrator (operator) and reducing communication loss. .
- Industrial applicability
- the present invention is useful for a router setting method for registering a new router in a virtual router system of a mobile IP (Internet Protocol) network and a router, and is particularly useful in a mobile router in which a network moves. Suitable for setting the period.
