Description

A kind of OSPF configuration method and related device

technical field

The present invention relates to the Internet field, in particular to an OSPF configuration method and related devices.

Background technique

A virtual cluster system is generally composed of multiple access nodes (AP, Access Point) and several core aggregation nodes (Master). APs generally use low-end routers or switches with small capacity and low performance; Capacity, high-performance routers or switches and other equipment. The Master has strong control and management capabilities and is used for centralized control and management of the virtual cluster system. The virtual cluster system only presents the Master to the outside world.

The current technology collects the network topology of the virtual cluster system by running the Open Shortest Path First protocol (OSPF, OpenShortest Path First) in the virtual cluster system, which requires the user to configure the process of the OSPF process running on each router in the cluster system ID (Process ID) and the router ID (Router ID) of the router in each process to run these OSPF processes smoothly.

However, the configuration of the Router ID requires the user to predict the network topology of the virtual cluster system and manually plan the Router ID of the router in each process according to the network topology. This operation is more complicated and the workload is heavy, which is not conducive to network configuration and installation. .

Detailed ways

An embodiment of the present invention provides an OSPF configuration method for simplifying manual OSPF operations. The embodiment of the present invention also provides a related Master, which will be described separately below.

A virtual cluster system generally consists of an AP and a Master, and the AP and the Master are connected to each other to form a network topology. The current technology collects the internal network topology of the system by running OSPF in the virtual cluster system. Take a basic structure of the virtual cluster system shown in Figure 1 as an example: in Figure 1, the first interface on the first Master and the second The interface is connected to the AP, and the third interface is connected to the second Master. The master runs an OSPF process on each interface, which requires the user to manually set the Process ID of the OSPF process running on each interface, and configure the router ID of the master in each OSPF process so that these OSPF processes can run smoothly. Manual configuration of these parameters requires the user to perceive the structure of the network topology in advance and manually plan the parameters according to the structure of the network topology, which requires a lot of manpower.

The embodiment of the present invention provides an OSPF configuration method, which can reduce the manual configuration operation of the Router ID of the Master. Please refer to FIG. 2 for its basic flow, including:

201. The first Master creates a first OSPF process, and adds the first interface to the first OSPF process;

The user manually enables the virtual cluster function on the first interface of the first master. After the virtual cluster function is enabled on the first interface, the first master automatically creates the first OSPF process and adds the first interface to the first OSPF in progress. Wherein, the first interface is an interface connected to the AP.

202. The first Master allocates the first Router ID in the first OSPF process;

After adding the first interface to the first OSPF process, the first Master allocates the first Router ID in the first OSPF process. Wherein, the Router ID is used to identify each router running the OSPF protocol, for example, it may be a 32-bit number. In an autonomous domain, this number can uniquely represent a router. In the virtual cluster system, the Router ID is used to uniquely identify the Master node in each OSPF process, and the first Router ID is used to uniquely identify the first Master node in the first OSPF process.

Wherein, there are many methods for the first Master to allocate the first Router ID in the first OSPF process, which will be described in detail in the following embodiments, and are not limited in this embodiment.

203. The first Master runs the first OSPF process.

After the first Master allocates the first Router ID in the first OSPF process, it can run the first OSPF process and establish an OSPF adjacency relationship with the AP.

In the method provided in this embodiment, after the virtual cluster function is enabled on the first interface, the first Master automatically creates the first OSPF process, adds the first interface to the first OSPF process, and automatically Assign the first Router ID, and finally run the first OSPF process. Through this method, the first Master can automatically assign the Router ID without manually planning the Router ID according to the network topology results, which simplifies the user's operation, reduces the user's workload, and is conducive to the configuration and installation of the virtual cluster system.

Wherein, after the first Master creates the first OSPF process, it may also assign a ProcessID to the first OSPF process. There are many ways for the first Master to assign Process IDs. For example, the Process ID assigned by the first Master can start from 65534. If the Process ID of 65534 is already occupied, the Process ID will be reduced by 1 to get 65533. If the Process ID is still occupied If it is occupied, the Process number will be reduced by 1 until a free Process ID is found. The first Master may also use other methods to allocate a Process ID. The Process ID is used to uniquely identify an OSPF process on the first Master, which is not limited in this embodiment of the present invention.

As mentioned in step 202, the first Router ID is used to uniquely identify the first Master in the first OSPF process. Preferably, as another embodiment of the present invention, the first Router ID may include a field for uniquely identifying the first OSPF process, so that the Router IDs of the first Master in different OSPF processes on the first Master do not conflict. The field that uniquely identifies the first OSPF process can be the Process ID of the first OSPF, and can also be a shorter numerical value or other forms, as long as the contents of this field are different in different OSPF processes on the first Master; the first Router The ID may also include a field for uniquely identifying the first Master. More preferably, the field for uniquely identifying the first Master may be a network device identifier (NEID, Network Entity ID) of the first Master.

It can be seen from FIG. 1 that among the interfaces of the first Master, interface 1 and interface 2 are connected to the same AP, and the links between these two interfaces and the AP belong to a repeated topology. In the current technology, when the router ID of the master is manually planned according to the network topology, the duplicate topologies can be manually merged to avoid path calculation errors caused by the duplicate topologies during the running of the OSPF process. On the basis of the embodiment shown in Figure 2, the embodiment of the present invention also provides a further OSPF configuration method, which can enable the Master to automatically merge duplicate topologies. Please refer to Figure 3 for the process:

301. The first Master creates a first OSPF process and a second OSPF process, and adds the first interface to the first OSPF process, and adds the second interface to the second OSPF process;

The user manually enables the virtual cluster function on the first interface and the second interface of the first master. After the virtual cluster function is enabled on the first interface, the first master automatically creates the first OSPF process and adds the first interface to the to the first OSPF process. After the virtual cluster function is enabled on the second interface, the first Master automatically creates a second OSPF process and adds the second interface to the second OSPF process. Wherein, the first interface and the second interface are interfaces connected to the same AP.

302. The first Master allocates the first Router ID in the first OSPF process, and allocates the second Router ID in the second OSPF process;

After the first Master adds the first interface to the first OSPF process, it allocates the first Router ID in the first OSPF process; and after adding the second interface to the second OSPF process, it allocates it in the second OSPF process Second RouterID. Wherein, the first Router ID is used to uniquely identify the first Master in the first OSPF process, and the second Router ID is used to uniquely identify the first Master in the second OSPF process.

Similar to the allocation method of the first Router ID, the second Router ID may include a field for uniquely identifying the second OSPF process, so that the Router IDs of the first Master in different OSPF processes on the first Master do not conflict. The field uniquely identifying the second OSPF process can be the Process ID of the second OSPF process, or a shorter numerical value or other forms, as long as the contents of this field are different in different OSPF processes on the first Master; the second Router The ID may further include a field for uniquely identifying the first Master, and the field for uniquely identifying the first Master may be the NEID of the first Master.

303. The first Master runs the first OSPF process and the second OSPF process;

After the first Master allocates the first Router ID in the first OSPF process, it can run the first OSPF process; after the first Master allocates the second Router ID in the second OSPF process, it can run the second OSPF process, Establish an OSPF adjacency relationship with the AP.

304. The first Master determines that the first OSPF process and the second OSPF process have collected duplicate topologies;

After the first Master runs the first OSPF process and the second OSPF process, the first OSPF process and the second OSPF process will collect the network topology of the virtual cluster system. The first Master determines that the first OSPF process and the second OSPF process have collected duplicate topologies.

There are many ways for the first master to determine that the first OSPF process and the second OSPF process have collected duplicate topologies. For example, the OSPF process run by the first master can obtain the router ID of the node whose identity type is Master in the topology where the first master resides. , if the two OSPF processes of the first Master obtain the same Router ID of the node whose identity type is Master, it means that the first Master accesses a duplicate topology. As shown in Figure 1, since both the first OSPF process and the second OSPF process are located in the first interface—AP—second interface of the closed-loop topology, the first OSPF process can obtain the Router ID used to identify the first Master as the first One Router ID and the second Router ID, the second OSPF process can obtain the Router ID used to identify the first Master as the first Router ID and the second Router ID; the first Master judges the first Router ID obtained from the first OSPF process A Router ID and a second Router ID are the same as the first Router ID and the second Router ID obtained from the second OSPF process, so it is determined that the first Master has collected duplicate topologies.

Among them, in order to obtain the Router ID of the node whose identity type is Master in the topology where the first Master is located, the OSPF process run by the first Master needs to first determine which nodes in the topology where the first Master is located have the identity type of Master and which nodes have the identity The type is AP. The identity type of each node can be carried in the Router Information Link State Advertise (RI LSA, Router Information Link State Advertise) of the node. There are many ways for the RI LSA to carry the identity type. For example, an extension field can be set for the RI LSA, and each node The identity type of the node is filled in the extension field of the node's RI LSA. In this way, after the RI LSA of the node is obtained, the identity type of the node can be determined according to the extension field of the RI LSA. The first Master obtains at least one RI LSA from the first OSPF process, and determines the node whose identity type is Master according to the obtained RI LSA, and then obtains the Router ID of the node whose identity type is Master from the first OSPF process, and obtains the first The router IDs of a Master are the first router ID and the second router ID. Similarly, the first Master obtains at least one RI LSA from the second OSPF process, and determines the node whose identity type is Master according to the obtained RI LSA, and then obtains the Router of the node whose identity type is Master from the second OSPF process. ID, the Router ID of the first Master is also the first Router ID and the second Router ID.

Other methods may also be used for the first Master to determine that the first OSPF process and the second OSPF process have collected duplicate topologies, which are not limited here.

305. The first Master merges the repeated topologies into one topology.

The first Master determines that the first OSPF process and the second OSPF process have collected duplicate topologies. For example, the first Master needs to merge the duplicate topologies into one topology, so as to avoid OSPF path calculation errors. Specifically, the first Master may add the second interface to the first OSPF process, and then delete the second OSPF process, so as to realize the merging of duplicate topologies.

This embodiment provides another OSPF configuration method based on the method provided in the embodiment shown in Figure 2, which enables the first Master to automatically identify and merge duplicate topologies, thereby avoiding path calculation errors and improving OSPF configuration accuracy. Success rate.

The OSPF configuration method in the foregoing embodiments is mainly for the interface connecting the first Master to the AP. But in a general virtual cluster system, the Master also needs to be connected. The embodiment of the present invention provides another OSPF configuration method on the basis of the embodiment shown in FIG. 2 , which can implement OSPF configuration between Masters. Please refer to Figure 4 for its process, including:

401. The first Master creates a first OSPF process and a third OSPF process, and adds the first interface to the first OSPF process, and adds the third interface to the third OSPF process;

The user manually enables the virtual cluster function on the first interface and the third interface of the first master. After the virtual cluster function is enabled on the first interface, the first master automatically creates the first OSPF process and adds the first interface to the to the first OSPF process. After the virtual cluster function is enabled on the third interface, the first Master automatically creates a third OSPF process, and adds the third interface to the third OSPF process. Wherein, the first interface is an interface connected to the AP, and the third interface is an interface connected to the second Master.

402. The first Master allocates the first Router ID in the first OSPF process, and allocates the third Router ID in the third OSPF process;

After the first Master adds the first interface to the first OSPF process, it allocates the first Router ID in the first OSPF process; and after adding the third interface to the third OSPF process, it allocates it in the third OSPF process Third Router ID. Wherein, the first Router ID is used to uniquely identify the first Master in the first OSPF process, and the third Router ID is used to uniquely identify the first Master in the third OSPF process. Wherein, the form of the third Router ID may be the management IP address of the first Master, and the management IP address is used to uniquely identify and manage a device in the virtual cluster system. The third Router ID may also be in other forms, which are not limited in this embodiment.

403. The first Master runs the first OSPF process and the third OSPF process;

After the first Master allocates the first Router ID in the first OSPF process, it can run the first OSPF process and establish an OSPF adjacency relationship with the AP; after the first Master allocates the third Router ID in the third OSPF process, it can Run the third OSPF process and establish an adjacency relationship with the second Master.

404. The first Master adds the adjacency description between the first Master and the second Master collected by the third OSPF process to the Router LSA of the first OSPF process.

After the first Master establishes OSPF adjacency with the second Master, the first Master can add the adjacency description between the first Master and the second Master to the Link State Advertisement (Router LSA) of the first OSPF process, wherein the adjacency The description is used to indicate that the first master and the second master are OSPF adjacent to each other.

After the first Master adds the description of the adjacency relationship between the first Master and the second Master to the Router LSA of the first OSPF process, the first Master-AP-second Master can successfully form a closed-loop topology.

The embodiment of the present invention provides a further OSPF configuration method based on the embodiment shown in FIG. 2 , wherein the first Master creates a third OSPF process, and adds the third interface connected to the second Master In the third OSPF process; in the third OSPF process, assign the third router to identify Router ID; run the third OSPF process and establish OSPF adjacency with the second Master; finally add the adjacency description with the second Master to the first OSPF In the Router LSA of the process. Through this method, the OSPF automatic configuration of the interface connected to the Master is realized, and there is no need to manually plan the Router ID of the interface connected to the Master according to the network topology results, which simplifies the user's operation, reduces the user's workload, and is beneficial Configuration and installation of the virtual cluster system.

Preferably, the data message between the first Master and the second Master can be transmitted through the link between the third interface and the second Master, and there is no need to set an additional interface for the first Master to be connected to the second Master, so that To achieve the purpose of saving the number of interfaces. Wherein, the third interface may be designated manually, or may be automatically set by the first Master, which is not limited in this embodiment of the present invention.

In order to facilitate understanding of the foregoing embodiments, a specific application scenario will be used as an example for description below.

Please still refer to Figure 1. In the illustrated virtual cluster system, the first interface and the second interface on the first Master are connected to the AP, and the third interface is connected to the second Master. The user manually enables the virtual cluster function on the first interface, the second interface, and the third interface of the first master, and the first master automatically creates the first OSPF process, the second OSPF process, and the third OSPF process, and assigns the first interface Add to the first OSPF process, add the second interface to the second OSPF process, and add the third interface to the third OSPF process.

The first Master allocates the first Router ID in the first OSPF process, allocates the second Router ID in the second OSPF process, and allocates the third Router ID in the third OSPF process. Wherein, the first Router ID includes a high-order byte for uniquely identifying the first OSPF process, and three low-order bytes written with the NEID of the first Master; the second RouterID includes a high-order byte for uniquely identifying the second OSPF process. The high-order byte, and the three low-order bytes written with the NEID of the first Master; the second Router ID is the management IP address of the first Master.

The first Master runs the first OSPF process, the second OSPF process and the third OSPF process, and collects the topology of the virtual cluster system through the running processes.

When collecting the topology, the first OSPF process obtains the first Router ID and the second Router ID of the first Master, and the second OSPF process also obtains the first Router ID and the second Router ID of the first Master. The first Master determines that the first and second Router IDs obtained by the first OSPF process and the second OSPF process are the same, and therefore confirms that the first OSPF process and the second OSPF process have collected duplicate topologies, so the first Master assigns the first The second interface is added to the first OSPF process, and then the second OSPF process is deleted.
