Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application.

The campus network mainly includes a terminal layer, an access layer, a convergence layer, and a core layer, as shown in fig. 1, where the terminal layer includes a terminal device accessing the campus network, such as: smart terminals, cell phones, personal Computers (PCs), printers, and the like. The access layer provides a campus network access function for the terminal device, and is the boundary of the campus network. The access layer comprises access equipment which can be in communication connection with the terminal equipment. The access device is connected with the network device of the convergence layer through an interface. The convergence layer connects the access layer and the core layer, and includes a convergence device. The core layer is the backbone area of the campus network and may be connected to the aggregation layer and other components of the campus network (if any). Other components of the campus network such as the data center. The core layer may be an egress of the campus network, the core layer including a core device.

In addition, the network device of the core layer is connected to a network (Internet or wide area network, WAN)) outside the campus through the network device of the exit area, so as to implement interaction of data information, where the network device of each layer in the campus network may be a switch or a router, and is not limited specifically herein.

Usually, a network device in the campus network is configured with a link state protocol, and based on the link state protocol, a route can be found, a route forwarding table is determined, and forwarding of a packet is guided. In order to enable the devices in the campus network to forward message information, link status information of all the devices in the campus network is usually stored in the LSDB of each device. As described in the background, in order to reduce the link-state information stored in the LSDB of each device, the LSDB may be configured separately in different areas by adding each interface of the network device configured with the OSPF protocol to a designated OSPF area manually, but this approach is time-consuming and labor-consuming by adding each network device interface to the OSPF area manually. In addition, when people are tired, configuration errors are prone to occur when a large amount of interface information is configured, once the configuration errors occur, the area where the interfaces belong is reconfigured, and the manual work pressure is too large.

Based on this, the application provides an interface configuration method for equipment in a campus network, so as to improve the configuration efficiency of equipment interfaces in the campus network.

It should be understood that, in the embodiment of the present application, the device role is also an identity of the network device in the campus network, where the identity is used to indicate a location of the network device in a network topology of the campus network, and for the present application, the device role includes: the device comprises a convergence device, a core device and an access device. If the device role is the convergence device, the network device connected with the device role can comprise a core device, an access device and a convergence device; if the device role is a core device, the network devices connected with the device role can comprise the core device and the convergence device; if the device role is an access device, the network devices connected to the device role may include an access device and an aggregation device.

The OSPF neighboring device is also a network device connected with the network device and supporting the OSPF protocol, and can perform information interaction with the network device through an OSPF message.

The OSPF area is that each network device is divided into a plurality of areas on the basis that the network device supports the OSPF protocol, and the LSDB is independently generated in different areas.

Wherein "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple. The singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

The device roles of the network devices in the campus network include aggregation device, core device, and access device, and the following application will respectively stand in the view of different device roles to explain how each device configures the OSPF area to which the interface belongs.

Fig. 2 is a flow diagram schematically describing an interface configuration method of a device in a campus network, where the device role is a convergence device, and the convergence device may first perform step 201 to obtain device roles of OSPF neighbor devices connected to respective interfaces of a network device, where the device roles of the OSPF neighbor devices may include an access device or a core device.

Step 202 is then executed, in which the aggregation device adds an interface connected to an OSPF neighbor device having a device role as a core device to the first OSPF area.

Step 203, the convergence device adds an interface connected with the first OSPF neighboring device into the second OSPF area, and the device role of the first OSPF neighboring device is an access device.

In addition, step 202 and step 203 in fig. 2 may not be in a sequential order, may be executed simultaneously, or may be executed in sequence, where step 203 is executed first and then step 202 is executed, or step 202 is executed first and then step 203 is executed, and the execution order is not specifically limited in this application.

For example, as shown in fig. 3, the interfaces of the convergence device 1 include an interface 1 to an interface 12. The OSPF neighbor device includes: core device 1, core device 2, access device 1, and access device 2. The convergence device 1 is connected with the core device 1 through an interface 1 and an interface 2; the convergence device 1 is connected with the core device 2 through an interface 3 and an interface 4; the convergence device 1 is connected with the access device 1 through an interface 5 and an interface 6; the convergence device 1 is connected with the access device 2 through an interface 7 and an interface 8. According to the interface configuration method of the devices in the campus network illustrated in fig. 2, the aggregation device 1 may add an interface 1, an interface 2, an interface 3, and an interface 4 to the OSPF area 1, and may add an interface 5, an interface 6, an interface 7, and an interface 8 to the OSPF area 2.

The convergence device can automatically add the interfaces connected with the OSPF neighboring devices into the designated area according to the device roles of the OSPF neighboring devices without configuring the areas of the network devices to which the interfaces belong one by one, thereby realizing the isolation of the information in the LSDB of the network device and improving the configuration efficiency of the interfaces in the campus network.

In one embodiment, the network device may further add an interface to the third OSPF area to connect with a second OSPF neighbor device, whose device role may be an access device. The method can add the interfaces of the convergence device connected with different access devices to different OSPF areas respectively, and isolate the interfaces of the network device connected with each access device in different OSPF areas, thereby further reducing link state information in the LSDB of the network device.

The OSPF neighbor device based on the convergence device 1 in fig. 3 includes: core device 1, core device 2, access device 1, and access device 2. The convergence device 1 may further add an interface 5 and an interface 6, which are used by the convergence device 1 to connect with the access device 1, to the OSPF area 2, and add an interface 7 and an interface 8, which are used by the convergence device 1 to connect with the access device 2, to the OSPF area 3, as shown in fig. 4. In addition, if the aggregation device 1 further includes an interface 13 and an interface 14, and the aggregation device 1 is connected to the access device 3 through the interface 13 and the interface 14, the aggregation device 1 may add the interface 13 and the interface 14 to the OSPF area 4, that is, when the aggregation device is connected to a plurality of access devices, the interfaces of the aggregation device connected to each access device are respectively added to different OSPF areas.

In one embodiment, the device role of the OSPF neighbor device may further include a sink device; the network device may add an interface to connect with an OSPF neighbor device having a device role of a convergence device into the first OSPF area. As shown in fig. 5, which is only specifically illustrated on the basis of fig. 3, the OSPF neighbor devices of the aggregation device 1 may further include an aggregation device 2 and an aggregation device 3. The convergence device 1 is connected with the convergence device 2 through an interface 9 and an interface 10; the convergence device 1 is connected with the convergence device 3 through an interface 11 and an interface 12. The convergence device 1 may add interface 9, interface 10, interface 11, and interface 12 to the OSPF area 1. The configuration efficiency of the device interface in the campus network can be improved by adding the OSPF neighbor device with the device role as the aggregation device into the first OSPF area.

In one embodiment, the network device may determine the device role of the OSPF neighbor device of the network device by:

the convergence equipment firstly acquires a message sent by OSPF neighbor equipment; wherein, the message is the message of OSPF protocol; the message of the OSPF protocol carries a field for indicating the device role of OSPF neighbor devices; the convergence device may then obtain the device role of the OSPF neighbor device according to the field in the message used to indicate the device role of the OSPF neighbor device.

The network device in the campus network exchanges information with the OSPF neighbor device through a message of the OSPF protocol, the aggregation device may receive the message of the OSPF neighbor device, and may determine the device role of the OSPF neighbor device by parsing a field indicating the device role of the OSPF neighbor device in the message, for example: the convergence device 1 receives a message 1 sent by the OSPF neighbor device, the convergence device 1 learns that the device role of the OSPF neighbor device is an access device by analyzing a field used for indicating the device role of the OSPF neighbor device in the message 1, and the convergence device 1 adds an interface connected with the OSPF neighbor device to a specified OSPF area according to the device role of the OSPF neighbor device.

Compared with the scheme that thousands of interfaces of the network equipment need to be manually configured to the OSPF areas, the network equipment only needs to manually configure the equipment role information of the network equipment, and only needs to acquire the equipment role fields in the messages sent by the OSPF neighbor equipment, so that the interfaces of the network equipment can be automatically added to the corresponding OSPF areas according to the equipment role information of the OSPF neighbor equipment. Compared with the method and the device which need to manually configure the interface information one by one, the method and the device only need to manually configure the device role information of the network device. Compared with the OSPF areas to which the interfaces belong configured manually one by one, the OSPF areas to which the interfaces belong are automatically configured through the network equipment, and the configuration efficiency of the interfaces is obviously improved. In addition, because the possibility of errors is high when thousands of interface information is manually configured, the method and the device automatically configure the interface information through the network equipment, and the possibility of configuration errors of the interface information is reduced.

Fig. 6 is a flow diagram schematically describing an interface configuration method of a device in a campus network from the perspective that a device role is a core device, where the core device may first perform step 601 to obtain device roles of OSPF neighbor devices connected to interfaces of a network device, where the device roles of the OSPF neighbor devices may include: a sink device and a core device.

Then, step 602 is executed, the core device adds an interface connected to an OSPF neighbor device having a device role as the core device to the first OSPF area.

Step 603, the core device adds an interface connected with the first OSPF neighbor device to the second OSPF area, and the device role of the first OSPF neighbor device is an aggregation device.

In addition, step 602 and step 603 in fig. 6 do not distinguish a sequence, and may be executed simultaneously, or according to the sequence, step 603 is executed first and then step 602 is executed, or step 602 is executed first and then step 603 is executed, and then the execution sequence is not specifically limited in this application.

For example, as shown in fig. 7, the interface of the core device 1 includes: interface 1 to interface 8. In practical application, the core device includes not only 8 interfaces, but the figure is only an example and does not limit the number of interfaces of the core device. The OSPF neighbor device includes: core device 2, core device 3, aggregation device 1, and aggregation device 2. The core equipment 1 is connected with the core equipment 2 through an interface 1 and an interface 2; the core device 1 is connected with the core device 3 through an interface 3 and an interface 4; the core equipment 1 is connected with the convergence equipment 1 through an interface 5 and an interface 6; the core device 1 is connected with the convergence device 2 through an interface 7 and an interface 8. According to the interface configuration method of the devices in the campus network illustrated in fig. 6, the core device 1 may add an interface 1, an interface 2, an interface 3, and an interface 4 to the OSPF area 1, and may add an interface 5, an interface 6, an interface 7, and an interface 8 to the OSPF area 2.

By the method, the core device can add the interface connected with the OSPF neighbor device to the appointed area according to the device role of the OSPF neighbor device, add the interface connected with the core device to the first OSPF area, and add the interface connected with the access device to the second OSPF area, thereby improving the configuration efficiency of the interface in the campus network.

In one embodiment, the core device may further add an interface to the third OSPF area that is connected to a second OSPF neighbor device whose device role is an aggregation device. That is, the interface 5 and the interface 6 connected to the aggregation device 1 in fig. 7 may be added to the OSPF area 2, and the interface 7 and the interface 8 connected to the aggregation device 2 may be added to the OSPF area 3 as shown in fig. 8, that is, when the core device is connected to a plurality of aggregation devices, the interfaces connected to the core device and each aggregation device are respectively added to different OSPF areas. By the method, interfaces of the aggregation equipment connected with the access equipment can be isolated in different OSPF areas, and the link state information in the LSDB of the network equipment is further reduced.

In one embodiment, a network device may determine a device role of an OSPF neighbor of the network device by:

the method comprises the steps that core equipment firstly obtains a message sent by OSPF neighbor equipment; wherein, the message is the message of OSPF protocol; the message of the OSPF protocol carries a field for indicating the device role of OSPF neighbor devices; and then the core device acquires the device role of the OSPF neighbor device according to the field for indicating the device role of the OSPF neighbor device in the message.

The network device in the campus network exchanges information with the OSPF neighbor device through a message of an OSPF protocol, the aggregation device may receive the message of the OSPF neighbor device, and determine the device role of the OSPF neighbor device by parsing a field indicating the device role of the OSPF neighbor device in the message, such as: the core device 1 receives the message 2 sent by the OSPF neighboring device, the convergence device 1 analyzes the field used for indicating the device role of the OSPF neighboring device in the message 2 to learn that the device role of the OSPF neighboring device is the convergence device, and the core device 1 adds the interface connected with the OSPF neighboring device to the appointed OSPF area according to the device role of the OSPF neighboring device.

Fig. 9 schematically illustrates an interface configuration method of a device in a campus network from the perspective that a device role of a station is an access device, where the access device may first perform step 901 to obtain device roles of OSPF neighbor devices connected to interfaces of a network device, where the device roles of the OSPF neighbor devices may include: an access device and a convergence device.

Step 902, if the OSPF neighbor devices of the network device include OSPF neighbor devices whose device roles are access devices, the network device adds an interface connected to the OSPF neighbor devices whose device roles are aggregation devices to the first OSPF area, and adds an interface connected to the OSPF neighbor devices whose device roles are access devices to the second OSPF area.

Step 903, if only the OSPF neighbor devices with the device role as the aggregation device are included in the OSPF neighbor devices of the network device, the network device adds an interface connected with the OSPF neighbor devices with the device role as the aggregation device to the second OSPF area.

In addition, step 902 and step 903 in fig. 9 do not distinguish a sequence, and may be executed simultaneously, or according to a sequence, step 903 is executed first and then step 902 is executed, or step 902 is executed first and then step 903 is executed, and then the execution sequence is not specifically limited in this application.

For example, as shown in fig. 10, the OSPF neighbor device of the access device 1 only includes: a convergence device 1 and a convergence device 2. The access device 1 is connected with the convergence device 1 through the interface 1 and the interface 2; the access device 1 is connected with the convergence device 2 through an interface 3 and an interface 4. The convergence device 1 may add interface 1, interface 2, interface 3, and interface 4 to the OSPF area 2.

The access device can be connected with the access device after being connected with the aggregation device, and because the access device is connected with other access devices besides the aggregation device, an interface for connecting the access device with the aggregation device can be moved from the OSPF area 2 to the OSPF area 1, wherein the LSDB of the OSPF area 1 can store more link state information relative to the LSDB of the OSPF area 2. When the access device is connected with the convergence device and then is connected with the access device, the interface for connecting the access device with the convergence device is added to the OSPF area 1, instead of configuring the interfaces for connecting the interface with the access device and other access devices in the OSPF area 2, so that the link state information stored in each network device LSDB in the OSPF area 2 can be reduced.

For example, as shown in fig. 11, the interface of the access device 1 includes: interface 1 to interface 8. The actual access device includes not only 8 interfaces, but the figure is only an example and does not limit the number of interfaces of the access device. The OSPF neighbor device of the access device 1 comprises: aggregation device 1, aggregation device 2, access device 2, and access device 3. The access device 1 is connected with the convergence device 1 through the interface 1 and the interface 2; the access device 1 is connected with the convergence device 2 through an interface 3 and an interface 4; the access equipment 1 is connected with the access equipment 2 through an interface 5 and an interface 6; the access device 1 is connected with the access device 3 through an interface 7 and an interface 8. According to the interface configuration method of the devices in the campus network illustrated in fig. 9, the aggregation device 1 may add the interface 1, the interface 2, the interface 3, and the interface 4 to the OSPF area 1, and may add the interface 5, the interface 6, the interface 7, and the interface 8 to the OSPF area 2.

In addition, it is also possible to add the

interfaces

5 and 6 for connecting the access device 1 and the access device 2 to the OSPF area 2, and add the interfaces 7 and 8 for connecting the access device 1 and the access device 3 to the OSPF area 3 as shown in fig. 12, that is, when the access device is connected to a plurality of access devices, the interfaces for connecting the access device and each access device are respectively added to different OSPF areas. In this way, interfaces of the network device connected with each access device are isolated in different OSPF areas, and link state information in the LSDB of the network device is further reduced.

the access equipment firstly acquires a message sent by OSPF neighbor equipment; wherein, the message is the message of OSPF protocol; the message of the OSPF protocol carries a field for indicating the device role of OSPF neighbor devices; and then the access device acquires the device role of the OSPF neighbor device according to the field for indicating the device role of the OSPF neighbor device in the message.

The network device in the campus network exchanges information with the OSPF neighbor device through a message of an OSPF protocol, and the access device may receive the message of the OSPF neighbor device, and determine the device role of the OSPF neighbor device by parsing a field indicating the device role of the OSPF neighbor device in the message, such as: the core device 1 receives the message 3 sent by the OSPF neighbor device, the access device 1 learns that the device role of the OSPF neighbor device is the convergence device by analyzing the field for indicating the device role of the OSPF neighbor device in the message 2, and the access device 1 adds the interface connected with the OSPF neighbor device to the specified OSPF area according to the device role of the OSPF neighbor device.

Compared with the scheme that thousands of interfaces of the network equipment need to be manually configured to the OSPF areas, the network equipment only needs to manually configure the equipment role information of the network equipment, and only needs to acquire the equipment role fields in the messages sent by the OSPF neighbor equipment, so that the interfaces of the network equipment can be automatically added to the corresponding OSPF areas according to the equipment role information of the OSPF neighbor equipment. Compared with the method and the device which need to manually configure the interface information one by one, the method and the device only need to manually configure the device role information of the network device. Compared with the method that the OSPF areas to which the interfaces belong are configured manually one by one, the OSPF area to which the interfaces belong is automatically configured through the network equipment, and the configuration efficiency of the interfaces is obviously improved. In addition, because the possibility of errors is high when thousands of interface information is manually configured, the method and the device automatically configure the interface information through the network equipment, and the possibility of configuration errors of the interface information is reduced.
