Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 2, fig. 2 is a schematic view of a communication network provided in this embodiment, the communication network may include a plurality of routing devices 100, and the routing devices 100 may be neighbors to each other. For example, the plurality of routing devices 100 are adjacent to each other in BGP (Border Gateway Protocol).
In this embodiment, one of the routing devices 100 is taken as a first routing device, and at least one other routing device 100 having a BGP neighbor relationship with the first routing device is taken as a second routing device to explain the scheme provided in this embodiment.
Referring to fig. 3, the present embodiment provides a method for processing a routing filtering policy applied to a first routing device, where the method at least includes steps S110 to S130, which are described in detail below.
Step S110, obtain the IRF policy that needs to be applied to the target second routing device.
In this embodiment, the IRF policy that needs to be applied may be configured by an administrator on the first routing device for a certain target second routing device. The IRF policy for the target second routing device may also be automatically generated by the first routing device according to the operating condition of the first routing device or the target second routing device.
Step S120, a notification packet carrying the IRF policy is generated.
The inventor finds that, in the ORF function in the prior art, an ORF Route update (ORF Route-refresh) message is defined, please refer to fig. 4, where the ORF Route update message includes a plurality of ORF entry fields (ORFentry), and the plurality of ORF entry fields may be used to record an ORF policy that needs to be applied to a neighbor device. The route equipment with the ORF function can receive and analyze the ORF route update report, obtain the ORF strategy information carried in the ORF route update report, and apply the ORF strategy to the route filtering mechanism in the outgoing direction.
Since the ORF route update packet has been defined in the prior art and has a format that can be analyzed by the routing device to obtain the ORF policy, in this embodiment, the ORF route update packet is modified based on the ORF route update packet defined in the prior art, so that the ORF route update packet becomes a notification packet that can be used to transmit IRF policy information.
For example, since the ORF route update packet already defines the parsing rule, in this embodiment, for the IRF policy that needs to be applied to the target second routing device, the first routing device may configure the IRF policy in the ORF entry field of the ORF route update packet and transmit the ORF policy to the target second routing device.
Then, in order to distinguish from the normal ORF route update packet, in this embodiment, the first routing device may generate, according to the IRF policy, an ORF route update packet carrying a preset identifier as the notification packet.
Optionally, the preset identifier may be an ORF type (ORFtype) field with a preset field value in the ORF route update packet. For example, in a normal ORF route update message, the value of the ORF type field is usually 3, and in this embodiment, in order to distinguish from a normal ORF route update message, the first routing device may generate an ORF route update message with a value of 4 of the ORF type field as a notification message for transferring the IRF policy.
Step S130, the notification message is sent to the target second routing device, so that the target second routing device filters the received routing information according to the IRF strategy.
In this embodiment, for different second routing devices, the first routing device may generate different notification messages through step S110 and step S120, and then send the notification messages to the corresponding second routing devices respectively.
Then, in the process of route advertisement, the first routing device may uniformly send the same route advertisement information to the second routing device, and the second routing device filters the route advertisement information according to the IRF policy recorded by the second routing device. In this way, the first routing device may not need to perform separate filtering for each different second routing device when sending the route advertisement, which reduces the data processing pressure of the first routing device.
Optionally, in this embodiment, the first routing device may record identity information of the second routing devices for the second routing devices that have sent the IRF policy, for example, record the second routing devices in a group, and in the process of advertising the routing information, perform uniform advertisement for the second routing devices in the group, and do not perform separate filtering processing in the outgoing direction.
Referring to fig. 5, the present embodiment further provides a method for processing a routing filtering policy applied to a second routing device, where the method at least includes step S210 and step S220, which are described in detail below.
Step S210, receiving a notification packet carrying an IRF policy sent by the first routing device.
Optionally, in this embodiment, the second routing device may receive an ORF route update packet sent by the first routing device. And then detecting whether the ORF routing update message carries a preset identifier.
For example, when the value of the ORF type field of the ORF route update packet is detected to be a preset value, it is determined that the ORF route update packet carries the preset identifier. Wherein the preset value may be 4.
And if the second routing equipment detects that the ORF route updating message carries the preset identifier, taking the ORF route updating message as a notification message carrying the IRF strategy.
Step S220, the IRF strategy is extracted, and the received routing information is filtered according to the IRF strategy.
In this embodiment, the second routing device may continuously obtain the IRF policy pushed by the first routing device from the notification message, and record the IRF policy. And then in the process of route advertisement, when the second routing equipment receives the route information advertised by the first routing equipment, filtering the route information according to the IRF strategy, thereby selectively receiving part of the route information advertised by the first routing equipment.
It is worth to be noted that, in this embodiment, one routing device 100 shown in fig. 1 may serve as a first routing device to push the IRF policy to other neighbors, and the routing device 100 may also serve as a second routing device to receive the IRF policy pushed by other neighbors.

For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The machine-readable storage medium 120 may store machine-executable instructions, for example, the machine-readable storage medium 120 stores instructions related to the routing filtering policy processing logic, and when executed by the processor 130, the machine-executable instructions cause the routing device 100 to implement the packet generation method provided by the embodiment.
