Embodiment 1

[0031] In order to solve the above problems, a regional server automatic backup technology is provided. When a device fails during election, the entire network can rely on the route synchronized by another device for forwarding, and re-elect the regional server and backup server at the same time. This ensures the stability of the entire network. The regional server and the backup server are in an equal mutual backup relationship, and the route selected during forwarding is selected according to the routing rules of BGP. Specifically, such as figure 1 As shown, the regional automatic networking method with backup server provided by the present invention comprises the following steps:

[0032] S1. Start the BGP protocol and the IGP protocol of all nodes in the area, and use the IGP protocol to obtain the link state information of the area;

[0033] S2. According to the link state information of the area, select two nodes as the area server and the backup server of the area res...

Embodiment 2

[0048] In this embodiment, a simple example of networking in an area is provided.

[0049] (1) First, the user follows the figure 2 As shown, connect to the network;

[0050] (2) collect the link state information of whole area by ISIS agreement, then select area server and backup server, take IP address as selection standard, choose IP address maximum router R1 as area server, next largest router R2 as backup server;

[0051] (3) R3 obtains the IP address information of the regional server R1 and the backup server R2 through ISIS (a link state-based IGP protocol). BGP uses R3, R1, R2, R1, and R2 as route reflectors, and R3 as a reflection Similarly, R4 obtains the IP address information of the regional server R1 and the backup server R2 through ISIS (a link state-based IGP protocol), and BGP establishes a connection between R4 and R1 and R2, and R1 and R2 serve as route reflections reflector, R4 is the reflector client;

[0052] (4) R1 and R2 can also obtain the informati...

Abstract

The invention discloses an area automatic networking method with a backup server, and provides a concept of the backup server. When networking is started, two servers are elected in an area accordingto link state information, one server is an area server, the other server is the backup server, the two servers are connected with other routers in a network, and synchronize routing. Under the normalcondition, the synchronous route of one server is randomly selected according to the route selection rule of the BGP for forwarding, if the regional server fails at the moment, forwarding can be immediately (or continuously) carried out according to the route of the backup server, and meanwhile, the election of a new regional server is carried out. According to the method, the stability of the automatic networking method can be ensured to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of network configuration, and in particular relates to a regional automatic networking method with a backup server. Background technique [0002] With the continuous development of Internet technology, the scale of the network is also increasing, and the number of nodes in the network is also increasing in a straight line. In order to solve the problems of high networking costs and difficult network deployment in traditional large-scale network deployment, the existing In a networking method, according to the link status information in the network, automatic networking is carried out to synchronize the routes in the autonomous domain. When the network changes, the devices in the network will be elected according to the new link status information obtained by the IGP protocol. Regional servers and border servers, and then use BGP to establish BGP connections between regional servers and other routers, and est...
