Problems solved by technology

That is to say, there is such a defect in the existing technology: before the time-to-live expires or before receiving the next valid router advertisement, the traffic of the host will be sent to a router that has failed, resulting in interruption of business traffic

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] The present invention provides a method and an auxiliary method for fast switching of a host gateway in an IRDP network, which are respectively applied to a core router and an IRDP router of the IRDP network. The network includes a core router and an IRDP router, and the core router is used to manage the lower-layer IRDP router , the IRDP router is a router running the IRDP protocol, and is used to notify hosts in the client network of currently available gateway router address information. For the specific architecture of the IRDP network system, please refer to figure 1 with figure 2 . The gateway router can be the same device as the IRDP router, distinguished by different interfaces, that is, there are two logically and one...

Abstract

The invention provides a method and a device for fast switching of a host gateway in an IRDP network. The method includes: the core router regularly detects the status information of the gateway routers of each host in the client network; when the core router detects that a gateway router among the gateway routers of the hosts in the client network fails, the core router Advertise a gateway update message to all IRDP routers it manages to trigger the corresponding IRDP router to update the gateway IP address for the affected host. The technical scheme of the invention can quickly switch to an effective gateway for the host after the gateway currently used by the host fails, so that the effectiveness of the host communication is strongly guaranteed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for fast switching of host gateways in an IRDP network. Background technique [0002] IRDP (ICMP Router Discovery Protocol, Router Discovery Protocol) is an extension of ICMP (Internet Control Message Protocol, Internet Control Message Protocol), which enables each router to periodically transmit an IRDP notification message from each multicast interface to notify The IP address of the interface. After receiving the IRDP notification message, the host discovers the addresses of neighboring routers, so that it can dynamically discover the IP address of the default gateway router. In a multi-router environment, IRDP also enables hosts to detect and correct errors due to gateway failures, simplifies network management tasks, and implements redundant configurations in the network. The protocol must be implemented on a host connected to the network, and o...
