Description

BGP routing information acquisition method, BGP routing information acquisition device, computer equipment and storage medium
Technical Field
The present invention relates to network management, and more particularly, to a BGP routing information collection method, apparatus, computer device, and storage medium.
Background
The existing network management systems are implemented by training devices in a network in turn based on SNMP, i.e., a simple network management Protocol, and cannot acquire real-time running conditions of any BGP (Border Gateway Protocol) route and historical data of route running.
SNMP is a traditional network management technique that does not have the ability to obtain BGP dynamic routes in real-time, which is of interest to network managers. BGP is a routing Protocol for autonomous systems operating over TCP (Transmission Control Protocol) and is used to exchange routing information between different autonomous systems. When two autonomous systems need to exchange routing information, each autonomous system must designate a node that operates BGP to exchange routing information with other autonomous systems on behalf of the autonomous system. The SNMP-based network management system is a device-level monitoring and management system based on periodic polling. Events occurring in the network between polling intervals may be missed and increasing the density of polling may increase the load on the network. Unfortunately, the SNMP protocol itself is unaware of problems internal to the BGP routing protocol. For example, some user feedback cannot access some networks, but from the view of the network management system, the states of all routers and links are normal, so it is difficult to determine where the problem is and how to troubleshoot the problem. In fact, as part of BGP routes are repeatedly declared and withdrawn, the routes are suppressed from being pulled into a blacklist and are no longer transmitted outward, so that some networks cannot be accessed, but current network management tools do not have the capability of collecting BGP real-time routing states, and fault location is not performed from the beginning.
Therefore, it is necessary to design a new method to realize real-time BGP routing information acquisition and solve the problem that SNMP cannot acquire BGP routes in real time.

Fig. 2 is a schematic flowchart of a BGP routing information collection method according to an embodiment of the present invention. The BGP routing information acquisition method is applied to an acquisition server. The collection server performs data interaction with a BGP route reflector in an autonomous system in a collection network route, and the collection server performs data interaction with the terminal.
Fig. 2 is a schematic flowchart of a BGP routing information collection method according to an embodiment of the present invention. As shown in fig. 2, the method includes the following steps S110 to S150.
S110, constructing a neighbor relation with a BGP route reflector in a certain autonomous system in the collection network route to obtain an IBGP neighbor.
In this embodiment, the IBGP neighbor refers to a connection relationship of an internal BGP protocol, and the IBGP neighbor provides more information to an internal router, and routers corresponding to the IBGP neighbor are connected in a full mesh structure.
The IBGP neighbors are established by using a BGP route reflector and an acquisition server in a certain autonomous system in the acquisition network route, the BGP route reflector can completely inform the route to the IBGP neighbors, the IBGP has the synchronization requirement, and BGP attributes or route changes in the whole autonomous system can be informed to the related IBGP neighbors through the BGP route reflector.
In this embodiment, each autonomous system has a BGP route, and the BGP route reflector is connected to a number of BGP routes through a BGP network. The BGP route reflector is connected with the acquisition router to acquire BGP route information in real time.
In an embodiment, referring to fig. 3, the step S110 may include steps S111 to S114.
S111, establishing TCP connection with a BGP route reflector in a certain autonomous system in the collection network route, and monitoring corresponding TCP initialization conditions.

S112, acquiring the opening message from the BGP route reflector, and driving the BGP route reflector to enter a state that the opening message is sent.
Specifically, after the TCP connection is established, the BGP route reflector sends an open message to the acquisition server, enters a state in which the open message has been sent, and waits until the acquisition server responds.
In this embodiment, the establishing of the neighbor relation includes six states, the first state is an idle state, and the state does not allow the connection of the BGP route reflector, that is, the connection of the BGP route, and does not allocate network resources; the second is a connection state, which indicates that the acquisition server and the BGP routing transmitter complete three-way handshake connection; the third is an active state, which is a state that the handshake fails or the opening message is sent without response and then enters; and the fourth state is a state that the opening message is sent after three-way handshake, which is equivalent to synchronizing the autonomous system, the version number and the keep-alive time, if the sending is successful, the idle state is entered, in the state, the TCP connection is already established, the BGP route also sends the first opening message, and the rest work is carried out, and the BGP route waits for the peer of the BGP route to send the opening message. And checking the correctness of the received opening message, if an error exists, the system sends an error notification message and returns to an idle state, and if no error exists, the BGP route starts to send the keep-alive message, resets a keep-alive message timer, starts to time and simultaneously shifts to an opening message confirmation state. And the fifth mode is an open message confirmation state, in which the BGP route sends a keep-alive message and resets a keep-alive timer, if a keep-alive message is received, the connection is established, the BGP neighbor relation is established, if the TCP connection is interrupted, the BGP route returns to an idle state, and the open message is confirmed after the open message is sent to the other side. The sixth is that the connection is established, sending keep alive message, if the connection is successfully received and enters the established state, failing to return to the idle state, and after the connection is established, sending keep alive message, updating message and error message, in this state, the BGP neighbor relation is established, at this time, BGP exchanges the updating message with its neighbors, and at the same time, the keeping timer is reset.
S113, sending an opening message to the BGP route reflector for the BGP route reflector to check and sending a keep-alive message by the BGP route reflector;
s114 responds to the keep-alive message and drives the BGP route reflector to transition to the state that the connection is established.
Specifically, after the TCP connection is established, the BGP route reflector sends an open message to the acquisition server and enters an open message sent state, and waits until the acquisition server responds; the acquisition server sends an opening message to the routing equipment; the BGP route reflector checks the opening message, and sends a keep-alive message after the check is successful; the collection server responds to the keep-alive message of the BGP route reflector, the state of the BGP route reflector is transited to the connection established state, and the neighbor establishment is completed;
and S120, setting the state of establishing the neighbor as the state of establishing the connection.
S130, obtaining the update information message and the keep-alive message from the BGP route reflector through the IBGP neighbors.
And when a routing event changes, the IBGP neighbors are notified through the update information message.
In this embodiment, the open message is sent at the beginning of establishing the connection, and it is used to invoke a call with the other side, including the version number of the BGP route, the number of the home-end autonomous system, the time of the keep-alive message of six times, and the ID number of the BGP router.
The update information includes an unreachable route length, an unreachable route, a path attribute length, a path attribute, and network layer reachability information. Specifically, the update information carries reachable routes and unreachable routes, and then carries attributes of all routes, and the message includes all valuable information; real-time information of the route can be obtained from the update information.
The keep-alive message comprises a message header for confirming whether the connection between the two neighbor parties is normal or not, and is a message with low overhead.
The error message is sent only when there is a problem in the connection, for example, when the negotiated parameters at the beginning of establishing the connection by the BGP are not matched, or some illegal messages are received, or for other reasons, the BGP sends the error message, and the BGP connection is interrupted while sending the error message. The contents are error code + error subcode + unmatched parameter information.
And S140, acquiring the attribute of the BGP route according to the updating information to obtain BGP route information.
In this embodiment, the BGP routing information refers to an attribute of the BGP route, and is a reachable route or an unreachable route, a corresponding path attribute length, a path attribute, and network layer reachability information.
And S150, feeding back the BGP routing information to a terminal for displaying at the terminal.
The acquisition server establishes an IBGP neighbor with the BGP reflector, and the neighbor establishing state is a connection established state, namely the acquisition server and the BGP reflector can exchange three messages of keep-alive messages, update messages and error messages. And completing the real-time collection of the BGP route by collecting the route information and the attribute in the update message.
The method comprises the steps that a TCP connection is established between an acquisition server and a BGP route reflector, and a BGP neighbor is established between the acquisition server and the BGP reflector through the interaction of message packets and the interaction of keep-alive message packets; after the BGP neighborhood is established between the collection server and the BGP route reflector, collecting the route information and the path attribute information of the update message; the acquisition server and the BGP route reflector continuously carry out neighbor keep-alive and collect BGP data change in real time; the collection server passively receives BGP routing data, and is different from a traditional polling device data collection mode.
The BGP routing information acquisition method realizes the exchange of the keep-alive message, the update message and the error report message with the BGP routing reflector by establishing the neighbor with the BGP routing reflector, finishes the real-time acquisition of the BGP routing by acquiring the routing information and the attribute in the update message, passively collects the BGP routing information, can acquire the BGP routing information and the change condition in real time, does not increase any network load, does not generate any influence on the network operation, realizes the real-time acquisition of the BGP routing information, and solves the problem that the SNMP cannot acquire the BGP routing in real time.
