Abstract
The invention discloses a method for periodically setting VRRP nodes as master nodes, which starts a periodic switching function: logging in a node B, and setting the cycle time for switching to a main node; when the period time meets a set value, the node B dynamically increases the operation priority to a maximum value m; the priority in the periodic notification message of the node A is pa; at this time, (m-pa) > q, node B elects to be the master node, and node a switches to be the backup node; when the period time does not meet the set value, the node B restores the dynamic priority to be the configuration priority pb; the priority in the periodic notification message of the node A is pa; at this time, (pa-pb) > q, node a elects to be the master node; meanwhile, the node B is switched into a backup node; the invention can periodically set the VRRP node as the main node, effectively ensures the effectiveness and the real-time performance of network deployment and network service, and improves the competitiveness of the product.
Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for periodically setting VRRP nodes as master nodes.
Background
VRRP (Virtual Router Redundancy Protocol) is composed of a main Router and a plurality of backup routers, and is functionally equivalent to a Virtual Router. Each router in the group periodically sends VRRP notification messages to all routers in the group to notify configuration information and working conditions (priority and the like), and according to the priority, a main router is selected to bear the gateway function. And the other routers serve as backup routers, and when the main router fails, the main router is replaced to continue to fulfill gateway responsibilities, so that the hosts in the network are ensured to continuously communicate with the external network.
With the rapid development of networks, in order to provide reliable data communication services, VRRP is widely adopted by manufacturers of various data communication products (routers, switches, firewalls, load balancing, etc.) to implement a cluster redundancy mechanism, thereby improving the reliability and competitiveness of the products.
Because of the numerous data communication products, the router of the VRRP is uniformly modified into the node.
In the prior art, under a VRRP networking environment, each VRRP node starts a preemption mode and competes out a master node according to each priority (default 150); if the priority of a certain backup node A is higher, but the priority difference value is not larger than the preemption threshold value compared with the main node, the main node and the backup node are not switched, otherwise, the node A is switched to the main node.
Due to the characteristics of network deployment and network service (such as different busy degrees of different bandwidth of the exit links in different time periods or different charges), a certain node needs to be periodically set as a main node, for example, the main node is 01:00-5:00 every night, and other time periods are backup nodes; however, the prior art cannot meet the requirement of periodically setting the VRRP node as the master node.
Therefore, a method for periodically setting the VRRP node as the master node becomes a problem to be solved urgently.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: a method for periodically setting a VRRP node as a master node comprises the following steps:
step 1: configuring a networking environment, wherein the networking environment comprises a VRRP dual-machine environment, a node A and a node B;
step 2: setting primary and secondary nodes of the node A and the node B when the periodic switching function is not started;
the node A starts VRRP, and the priority is configured to pa; starting a preemption mode; the priority in the periodic notification message of the node A is pa;
the node B starts VRRP and configures the priority as pb; starting a preemption mode; the priority in the periodic notification message of the node B is pb;
configuring a preemption threshold value q of a networking environment;
at this time, (pa-pb) > q, node a elects to be the master node; the node B is a backup node;
and step 3: and starting a periodic switching function: logging in a node B, and setting the cycle time for switching to a main node;
when the cycle time meets a set value, the node B dynamically increases the operation priority to a maximum value m; the priority in the periodic notification message of the node B is m; the priority in the periodic notification message of the node A is pa;
at this time, (m-pa) > q, node B elects to be the master node, and node a switches to be the backup node;
when the cycle time does not meet the set value, the node B restores the dynamic priority to be the configuration priority pb; the priority in the periodic notification message of the node B is pb; the priority in the periodic notification message of the node A is pa;
at this time, (pa-pb) > q, node a elects to be the master node; and the node B switches to the backup node.
