Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a diagram of a data transmission method provided in an embodiment of the present application, where the method is applied to a DVPN, where the DVPN may include a plurality of central end devices, each of the plurality of central end devices may be connected to a plurality of mesh point devices, and each of the central end devices and each of the mesh point devices may be provided with a DVPN module. Any mesh point device in the plurality of mesh point devices can execute the data transmission method provided by the embodiment of the application. The method includes the following steps S120 to S130:
step S120, identifying the route configuration element with the identification by using a preset route protocol, and acquiring the route message which needs to be correspondingly sent according to the route configuration element with the identification.
The preset routing protocol is a routing protocol operated by a routing device executing the data transmission method, and may be an OSPF protocol or a BGP protocol.
The routing configuration element is an element which needs to be configured by the routing device in order to generate a routing relationship with other routing devices, and corresponds to a specific type of a preset routing protocol. For example, if the preset routing protocol is an OSPF protocol, the corresponding routing configuration element is a DVPN virtual interface of the routing device, which is configured with a private network address; if the preset routing protocol is a BGP protocol, the corresponding routing configuration element is a configured neighbor relationship between the routing device and at least one routing device in the DVPN network.
For the DVPN virtual interface with the identification, no routing neighbor is established, so that data is not transmitted in a routing neighbor relation manner; but transmits data through the DVPN module corresponding to the routing device where the identified DVPN virtual interface is located.
The routing message contains information required for establishing a routing relation, and corresponds to the specific type of the preset routing protocol. For example, for the OSPF protocol, the corresponding routing message is an LSA generated according to an interface overlay condition by using the OSPF protocol; for the BGP protocol, the corresponding routing message is a routing packet, and the routing packet includes next hop device information and a private network address mask. The routing device passes the routing message to the DVPN module of the routing device itself.
Step S130, sending the routing message by DVPN message format through DVPN virtual interface of the device. Any network point device in the DVPN can identify the route configuration element with the identification according to the corresponding routing protocol, further obtain the route message, and send the route message to the target routing device through the DVPN module of the routing device, thereby establishing the private network intercommunication between the routing device and the target routing device. The target routing device may be a central device or a mesh point device. Compared with the prior art, the embodiment does not need to establish the neighbor relation between the mesh point equipment and the central end equipment, and can directly utilize the DVPN module of the routing equipment to send the routing message so as to realize the establishment of the routing relation between the mesh point equipment and the central end equipment and between the mesh point equipment and the central end equipment, realize private network intercommunication and effectively reduce the operation pressure of the central end equipment.
Optionally, in a specific embodiment, before step S120, the method may further include:
step S110, identifying the routing configuration element of the device according to a preset routing protocol.
The time for identifying the routing configuration element may be when the routing device initializes.
Optionally, referring to fig. 2, fig. 2 shows a specific implementation of the data transmission method provided in the embodiment of the present application, and specifically includes the following steps S211 to S241:
step S211, identify the DVPN virtual interface of the device according to the OSPF protocol.
Step S221, using OSPF protocol to identify the DVPN virtual interface with the identifier.
Step S222, acquiring a link state advertisement LSA of the OSPF protocol that needs to be sent through the DVPN virtual interface.
After the routing device identifies the DVPN virtual interface with the identifier by using the OSPF protocol, the routing device does not send a HELLO message at the DVPN virtual interface to establish a neighbor relation with the central point device, but directly takes the DVPN virtual interface as AREA 0 of the OSPF, and generates a link state advertisement LSA according to the interface coverage condition by using the OSPF protocol. The link state advertisement LSA may include a first type LSA and a second type LSA, where the first type LSA is a Router LSA and the second type LSA is a Network LSA.
The type of the DVPN virtual interface may be a point-to-multipoint type, or a broadcast type. The opposite end interface information required for generating the first type LSA and the second type LSA can be obtained from the DVPN dynamic mapping table. If the information in the DVPN dynamic mapping table changes, the DVPN module can acquire the change condition of the DVPN dynamic mapping table and transmit the change condition to the OSPF process, so that the OSPF process can make a corresponding change according to the change.
And transmitting the routing message to the DVPN module of the routing message.
The routing message is the link state advertisement LSA, and the routing device transmits the link state advertisement LSA to the DVPN module of the routing device after generating the link state advertisement LSA.
Step S231, sending the LSA of the OSPF protocol, which needs to be sent through the DVPN virtual interface, through the DVPN virtual interface.
All the routing devices except the self routing device in the DVPN can receive the link state advertisement LSA, and all the routing devices except the self routing device in the DVPN comprise all other central end devices except the routing device in the DVPN and all mesh point devices.
After each of the above-mentioned all the routing devices receives the broadcast by using its own DVPN module, it extracts the link-state advertisement LSA therein, and transmits the link-state advertisement LSA to the corresponding process running the OSPF protocol of each routing device, thereby forming the routing relationship.
After all the routing devices complete the processing procedure, logical AREA 0 AREAs can be formed among all the DVPN virtual interfaces of the DVPN, and routing relationships among all the DVPN virtual interfaces of the DVPN can be formed.
In a specific embodiment, after step S241, the method may further include: generating a third type LSA for the interface except the DVPN virtual interface by using an OSPF inter-domain route notification method; transmitting the third type LSA to a DVPN module of the LSA; and broadcasting the third type LSA to all routing devices except the DVPN by utilizing the DVPN module of the DVPN.
The third type of LSA is Network summary LSA. For the interfaces of the routing device except for the DVPN virtual interface, a third-type LSA may be generated by using an OSPF inter-domain route advertisement method, and the third-type LSA is transferred to the DVPN module of the routing device itself, so that the routing device broadcasts the third-type LSA to all but its own DVPN modules in the DVPN.
After each of the above-mentioned all the routing devices receives the broadcast by using its own DVPN module, it extracts the third type LSA, and transmits the third type LSA to the corresponding process running the OSPF protocol of each routing device, thereby forming the routing relationship.
After all the routing devices complete the above processing procedures, routing relationships between all the interfaces of the DVPN can be formed, and all the private network route announcements are completed.
In a specific embodiment, referring to fig. 4, the data transmission method provided in the present application may further include the following steps S410 to S420:
step S410, receiving a second preset type LSA sent by a router device except the DVPN itself by using the DVPN module of the router device.
The second preset type LSA is an LSA sent by other routing devices in the DVPN, and the LSA may be a first type LSA, a second type LSA, or a third type LSA.
Step S420, using the OSPF protocol process to process the second preset type LSA, so as to form a routing relationship between the routing device sending the second preset type LSA and the routing device.
The DVPN module of the routing device may transfer the second preset type LSA to a process running the OSPF protocol, and process the second preset type LSA by using the process running the OSPF protocol, so as to obtain a routing relationship between the routing device that sends the second preset type LSA and the routing device.
In a specific embodiment, the central device may still be a Designated Router (DR) or a Backup Designated Router (BDR).
Optionally, referring to fig. 3, fig. 3 shows another specific implementation of the data transmission method provided in the embodiment of the present application, which specifically includes the following steps S311 to S341:
step S311, identify a BGP neighbor to be established through the DVPN configured by the device according to the BGP protocol.
Step S321, when a routing relation is to be established with the BGP neighbor with the identifier, a routing message to be sent to the BGP neighbor is acquired.
And step S331, sending the routing message through a DVPN virtual interface of the device by adopting a DVPN message format.
In the BGP protocol, usually, a neighbor relationship between each two routing devices may be configured in advance, so as to establish a connection between the routing devices according to the neighbor relationship. The pre-configured neighbor relation may be manually configured by a worker, and the neighbor relation may be recorded in a DVPN mapping table of the corresponding routing device. For example, if the routing device a and the routing device B are configured with a neighbor relationship, the DVPN mapping table of the routing device a records a configured BGP neighbor address, that is, an address of the routing device B, and the DVPN mapping table of the routing device B records a configured BGP neighbor address, that is, an address of the routing device a.
However, in this embodiment of the present application, the configured neighbor relationship of the routing device is identified first, and then when the neighbor relationship is to be established really according to the neighbor relationship, the neighbor relationship is not established really, but a routing packet is generated through a process of running a BGP protocol of the routing device, and then the routing packet is transmitted to the DVPN module of the routing device, so that the routing device sends the routing packet to an opposite-end routing device that originally intends to establish the neighbor relationship by using the DVPN module of the routing device. The opposite-end routing device is a BGP neighbor to be established through the DVPN, i.e., a target routing device.
The target routing device receives the routing message by using the DVPN module of the target routing device, and transmits the routing message to the process running the BGP protocol so as to process the process running the BGP protocol, thereby generating a routing relation.
After all the routing devices complete the above processing procedures, routing relationships between all the interfaces of the DVPN can be formed, and all the private network route announcements are completed.
In a specific embodiment, the center device may still be used as a Route Reflector (RR), and the mesh point device may still be used as an RR client.
