Routing device and method for transmitting routing

Abstract

The present invention discloses a method of releasing and sending route with a routing equipment, which comprises the following processes that weather the routing equipment is in the primary condition is detected; the routing equipment spans the routing information, and marks the results in the routing information; the routing information is sent. The embodiment of the present invention makes the routing information have the describing marker ability of the main / standby equipment through arranging the routing attributes (public attributes or private attributes) of the routing information, and influences the route selection of the far end routing equipment after the routing information is sent, therefore ensures that the far end routing equipment selects the main routing equipment main route to the forward message, and ensures the accessibility and connectivity of the network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for sending a route and a corresponding routing device. Background technique [0002] In order to improve the reliability and security of the network, redundant backup of routing equipment (for example: backup firewall equipment) is often required in the network, that is, to set up a main routing device and at least one backup routing device. When the active routing device is used for work, when the active routing device fails, the backup routing device will be promoted to the active routing device and take over the work of the active routing device. However, in the process of implementing the present invention, the inventor found that at least the following problems existed in the prior art: in the process of interaction and cooperation between the routing device and the routing protocol, the message that should have been forwarded to the active routing de...

Problems solved by technology

However, in the process of implementing the present invention, the inventor found that at least the following problems existed in the prior art: in the process of interaction and cooperation between the routing device and the routing protocol, the message that should have been forwarded to the active routing device was forwarded to the backup router On the device, because the backup routing device does not have the state information of the packet, it discards the packet, which causes problems such as packet loss

However, the downlink traffic from the external network to the internal network must also enter the internal network through the primary routing device. If the external network chooses the backup routing device to forward packets, since there is no IP connection status information on the backup routing device, the backup The routing device will discard the packet, as shown in Figure 2

[0004] Therefore, the disadvantage of the prior art is that it cannot guarantee that when the active routing device is working normally, the message will always pass through the active routing device, so as to avoid the message loss caused by the message being forwarded to the backup routing device.
