Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
With the rapid development of networks, the exchange amount of routing information is increasing, and when BGP devices send all the routing information of their own peers to BGP neighbor devices, it takes a while to complete the sending of the routing information, which results in low efficiency of sending the routing information. In addition, the transmission of a large number of update messages also increases the burden on the network link.
One of the core ideas of the application is that a current routing sending attribute corresponding to current routing information of target neighbor information is obtained, and whether the current mapping relation among the current routing information, the target neighbor information and the current routing sending attribute is matched with a pre-stored mapping relation is judged by inquiring the pre-stored mapping relation; if not, it may be determined that the route transmission attribute of the current route information has changed, or the current route information has not been transmitted to the target neighbor device, and the current route information may be transmitted to the target neighbor device. Therefore, the embodiment of the application can filter the current routing information which needs to be sent to the target neighbor device, so that the BGP device only sends the routing information which has the changed routing sending attribute or has not been sent to the target neighbor device, but not sends all the routing information, thereby improving the efficiency of sending the routing information and reducing the network link burden of transmitting the routing information.
Referring to fig. 2, a flowchart illustrating steps of a method for processing routing information according to an embodiment of the present application is shown, where the method is applied to a BGP device, and the method may specifically include the following steps:
the embodiment of the application can be applied to BGP route switching equipment (such AS BGP routers, hereinafter referred to AS BGP equipment for short), and the BGP equipment can be positioned among different ASs or in the same AS. It should be noted that, in the embodiments of the present application, BGP devices in the same AS are used AS an example for description, and routing information processing processes of BGP devices between different ASs are similar and refer to each other.
The target neighbor information may specifically be identification information such as a device name or a Media Access Control (MAC) address of the target neighbor device. In a specific application, an outbound routing policy for BGP devices to send routing information to corresponding target neighbor devices may be configured, where the routing policy may be used to configure a routing attribute corresponding to the routing information. When the outbound routing policy changes, the corresponding routing attributes may also change. In addition, when an ACL (Access Control List), a route itself, or the like changes, a route transmission attribute also changes. The routing transmission attribute in the embodiment of the present application refers to a routing attribute that is required to be transmitted to the outside after the routing information of the BGP device is filtered by the current outgoing direction routing policy.
According to the embodiment of the application, when the BGP equipment needs to send the routing information to the target neighbor equipment, the current routing information can be filtered, so that the BGP equipment only sends the routing information with the changed routing sending attribute or which is not sent yet to the target neighbor equipment, and the problem that all routing information needs to be sent to the target neighbor equipment again when an outgoing routing strategy or an ACL and the like of the BGP equipment sending the routing information to the target neighbor equipment are changed is solved.
Optionally, the outbound routing policy includes, but is not limited to, any one or any combination of the following:
ORIGIN policy, AS _ PATH policy, NEXT _ HOP policy, MULTI _ EXIT _ DISC policy, LOCAL _ PREF policy, Community policy, Extcomunity policy.
Wherein, the ORIGIN of the route is indicated by the ORIGIN of the ORIGIN policy, which can be obtained from the inside of the autonomous domain, from the outside of the autonomous domain, or through other ways; AS _ PATH policy, i.e. a list of autonomous domains that the route passes through; NEXT _ HOP policy, i.e. NEXT HOP address of the route; the MULTI _ EXIT _ DISC strategy is that the routing with lower MED value is preferentially selected when routing selection is carried out, namely the weight of the routing from outside the autonomous domain; LOCAL _ PREF strategy, the preferred grade of the route in the autonomous domain, when selecting the route, the route with higher value is preferentially selected; community policies, i.e., Community properties; extcommunity policy, i.e., extending community attributes.
In an application example of the present application, the BGP networking shown in fig. 1 is taken as an example. Assume that the following 100 pieces of static routing information are configured in the RTA: 1.1.1.1/32, 1.1.1.2/32 up to 1.1.1.100/32. The static routing information is introduced into a BGP protocol on the RTA, the static routing information can be sent to BGP neighbor equipment RTB through the BGP protocol, and meanwhile, the RTB can configure a directional routing strategy on the RTA for controlling routing sending attributes when the static routing information is sent to the RTB. Assuming that the outbound routing policy configured by the static routing information includes a LOCAL _ PREF policy, and the current routing transmission attribute corresponding to the current routing information (1.1.1.1/32) is modified to be LOCAL-reference equal to 100 according to the configured LOCAL _ PREF routing policy, it can be known that the current routing transmission attribute corresponding to the current routing information (1.1.1.1/32) is: local-prediction is 100.
In the embodiment of the present application, after configuring the corresponding outgoing direction routing policy for the routing information, the mapping relationship between the routing information, the target neighbor information, and the preset routing sending attribute may be stored. The preset routing transmission attribute may represent a routing attribute when the routing information set when the direction routing policy is configured is transmitted to the target neighbor. When the current mapping relationship is not matched with the pre-stored mapping relationship, it may be determined that a route transmission attribute of the current routing information has changed, or the current routing information has not been transmitted to the target neighbor device, and the current routing information may be transmitted to the target neighbor device.
In an optional embodiment of the present application, it may be determined that the current mapping relationship and the pre-stored mapping relationship do not match through the following steps:
and when the mapping relation aiming at the target neighbor information does not exist in the pre-stored mapping relation, judging that the current mapping relation is not matched with the pre-stored mapping relation.
In a specific application, if the mapping relationship for the target neighbor information does not exist in the pre-stored mapping relationships, which indicates that the BGP device has not sent the current routing information to the target neighbor device, the current routing information may be sent to the target neighbor device.
In the first application example of the present application, the BGP networking shown in fig. 1 is still taken as an example. Assume that 100 pieces of static routing information are configured in the RTA, including: 1.1.1.1/32, 1.1.1.2/32 up to 1.1.1.100/32. After configuring the LOCAL _ PREF routing policy for the 100 pieces of static routing information, the mapping relationship between the routing information, the target neighbor information, and the preset routing sending attribute may be stored. Referring to table 1, a specific illustration of a mapping relationship between routing information, target neighbor information, and a preset routing attribute according to the present application is shown.
TABLE 1
| Routing information | Target neighbor information | Preset routing delivery attributes |
| 1.1.1.1/32 | Neighbor RTB | local-preference＝100 |
| 1.1.1.2/32 | Neighbor RTB | local-preference＝100 |
| …… | …… | …… |
| 1.1.1.100/32 | Neighbor RTB | local-preference＝100 |
Assuming that the current routing information is 1.1.1.101/32, the target neighbor information is a neighbor RTB, and the current routing transmission attribute is local-reference equal to 100, by looking up the mapping relationship shown in table 1, where there is no mapping relationship matching the current routing information 1.1.1.101/32 and the target neighbor information neighbor RTB, it indicates that the BGP device has not transmitted the routing information to the neighbor RTB, and may transmit the routing information 1.1.1.101/32 to the RTB.
Optionally, after sending the current routing information to the target neighbor device, the BGP device may further newly create, in the pre-stored mapping relationship, a mapping relationship corresponding to the current routing information, the target neighbor information, and the current routing transmission attribute. Therefore, when the BGP device receives the current routing information the next time, the corresponding mapping relationship may be matched, and if the policy of the current routing information is not changed, the current routing information may not be sent to the target neighbor device any more, so as to reduce the network link load.
In the first application example, after the BGP device sends the routing information 1.1.1.101/32 to the target neighbor device (neighbor RTB), a corresponding mapping relationship may be newly established in table 1, and a specific illustration after a mapping relationship is newly added to table 1 is shown with reference to table 2.
TABLE 2
In another optional embodiment of the present application, it may be further determined that the current mapping relationship and the pre-stored mapping relationship do not match through the following steps:
when a mapping relation aiming at the target neighbor information exists in a pre-stored mapping relation, acquiring preset routing sending attributes corresponding to the current routing information and the target neighbor information from the pre-stored mapping relation;
and when the current routing sending attribute is inconsistent with the preset routing sending attribute, judging that the current mapping relation is not matched with the pre-stored mapping relation.
In a specific application, after the outbound routing policy is changed, a current routing sending attribute corresponding to current routing information obtained according to the changed outbound routing policy is also changed, and at this time, the current routing sending attribute is inconsistent with a pre-stored preset routing sending attribute, and it is determined that the current mapping relationship is not matched with the pre-stored mapping relationship. At this point, the current routing information may be sent to the target neighbor device.
In application example two of the present application, the BGP networking shown in fig. 1 is still taken as an example. As shown in table 1, it is assumed that the preset routing transmission attribute of the above 100 pieces of static routing information defaults to: the local-prediction is 100, the user modifies the outgoing direction routing strategy corresponding to the neighbor RTB, the routing sending attribute corresponding to the routing information 1.1.1.1/32 is modified into 200, and the outgoing direction routing strategy of other routing information keeps the default value unchanged.
When the RTA needs to send routing information to the neighbor RTB, taking routing information 1.1.1/32 as the current routing information as an example, according to the outgoing direction routing policy corresponding to the current routing information, the current routing sending attribute corresponding to the current routing information (1.1.1.1/32) can be obtained as follows: local-prediction is 200. And by looking up the mapping relationship shown in table 1 by the current routing information (1.1.1.1/32) and the target neighbor information (neighbor RTB), it can obtain that the corresponding preset routing transmission attribute is local-reference which is 100. Since the current routing transmission attribute is not consistent with the preset routing transmission attribute, it can be determined that the routing transmission attribute of the current routing information (1.1.1.1/32) is changed, and thus, the current routing information (1.1.1.1/32) can be transmitted to the target neighbor device (neighbor RTB). Because the route sending attribute of the other 99 pieces of route information is not changed, the 99 pieces of route information are not needed to be sent, so that the quantity of route information sent by BGP equipment to neighbor equipment can be greatly reduced, the route information sending efficiency can be improved, and the network link burden of transmitting the route information can be reduced.
In yet another optional embodiment of the present application, the method may further comprise:
and updating preset routing sending attributes corresponding to the current routing information and the target neighbor information according to the current routing sending attributes.
In the second application example, after the BGP device sends the current routing information (1.1.1.1/32) to the target neighbor device (neighbor RTB), since the routing attribute of the routing information has changed, the mapping relationship shown in table 1 may be updated, and the preset routing attribute corresponding to the routing information (1.1.1.1/32) is updated to local-prediction ═ 200. Referring to table 3, a detailed illustration of the updated table 1 is shown.
TABLE 3
| Routing information | Target neighbor information | Preset routing delivery attributes |
| 1.1.1.1/32 | Neighbor RTB | local-preference＝200 |
| 1.1.1.2/32 | Neighbor RTB | local-preference＝100 |
| …… | …… | …… |
| 1.1.1.100/32 | Neighbor RTB | local-preference＝100 |
In this embodiment, the mapping relationship may specifically be a triple. In a specific application, a triple (referred to as a sending triple in this embodiment) may be established and maintained in the BGP device, where the triple may be used to filter current routing information that the BGP device needs to send to a target neighbor device, and record routing information that the BGP device has sent. The composition of the triplet may specifically be as follows: < routing information, target neighbor information, preset routing transmission attribute >.
In an application example three of the present application, as shown in fig. 1, assuming that the preset routing transmission attribute of all routing information configured on the RTA and sent to the RTB is attribute a, the following 100 sending triples may be stored on the RTA: <1.1.1.1/32, neighbor RTB, Attribute A >, <1.1.1.2/32, neighbor RTB, Attribute A > up to <1.1.1.100/32, neighbor RTB, Attribute A >. And the outbound routing policy of the RTA sending the routing information to the RTB changes, for example, the routing sending attribute corresponding to the routing information 1.1.1.1/32 is modified to attribute B.
Taking the current routing information as 1.1.1.1/32 as an example, the current routing sending attribute corresponding to the current routing information (1.1.1.1/32) obtained according to the modified outgoing direction routing policy is attribute B. And inquiring in the sending triple according to the current routing information (1.1.1.1/32) and the target neighbor information (neighbor RTB) to obtain that the corresponding preset routing sending attribute is attribute A, if the current routing sending attribute of the current routing information (1.1.1.1/32) is not consistent with the preset routing sending attribute, the current routing information (1.1.1.1/32) can be sent to the neighbor RTB. Next, the next piece of routing information (e.g., 1.1.1.2/32) is used as the current routing information to perform the above operation.
After acquiring a current routing sending attribute corresponding to current routing information according to an outgoing direction routing strategy corresponding to the current routing information, taking the current routing information and target neighbor information as query keywords to query in an existing sending triple. If there is no matching sending triple, which indicates that the BGP device has not sent the current routing information to the target neighbor device, the BGP device may send the current routing information to the target neighbor device. After sending, a corresponding sending triplet may be newly created according to the current routing information, the target neighbor information, and the current routing sending attribute, for example, the following sending triplets are newly created: <1.1.1.1/32, neighbor RTB, Attribute B >, which indicates that the BGP device has sent routing information including Attribute B1.1.1/32 to neighbor RTB. And if the BGP equipment sends the routing information to the neighbor RTB again, if the routing sending attribute of the routing information 1.1.1.1/32 still keeps the attribute B unchanged, the BGP equipment does not need to send the routing information to the neighbor RTB again.
It is to be understood that the above description of representing the mapping relationship by using the triplet is only an application example of the present application, and the present application does not limit the specific form of the mapping relationship.
To sum up, according to the outbound routing policy corresponding to the current routing information of the target neighbor information, the embodiment of the present application obtains the current routing sending attribute corresponding to the current routing information, and by querying the mapping relationship stored in advance, when the current routing information, the target neighbor information, and the current mapping relationship between the current routing sending attributes are not matched with the mapping relationship stored in advance, it may be determined that the routing sending attribute of the current routing information has changed, or the current routing information has not been sent to the target neighbor device, and then the current routing information may be sent to the target neighbor device. Therefore, the embodiment of the application can filter the current routing information which needs to be sent to the target neighbor device, so that the BGP device only sends the routing information with the changed routing sending attribute to the target neighbor device instead of sending all the routing information, thereby improving the efficiency of sending the routing information and reducing the network link burden of transmitting the routing information.
In another embodiment of the present application, when the current mapping relationship is not matched with the pre-stored mapping relationship, the current routing information may be added to a to-be-sent list and then packaged and sent, so as to improve the efficiency of sending the routing information, referring to fig. 3, a flowchart of steps of a routing information processing method according to another embodiment of the present application is shown, and specifically, the method may include the following steps:
301, obtaining a current routing sending attribute corresponding to current routing information according to an outgoing direction routing strategy corresponding to the current routing information of target neighbor information;
and step 304, sending the current routing information in the list to be sent to the BGP neighbor device corresponding to the target neighbor information.
In this embodiment of the present application, when the BGP device needs to send routing information to a target neighbor device, the routing information to be sent may be added to a list to be sent corresponding to the target neighbor device. The list to be sent may be a linked list or a queue, and the specific form of the list to be sent is not limited in the embodiment of the present application. Taking a linked List as an example, assuming that the BGP device RTA needs to send routing information to the target neighbor device RTB and the RTC, a linked List1 may be established in the RTA, where the List1 may include routing information to be sent to the RTB, and a linked List2 may be established, and the List2 may include routing information to be sent to the RTC.
Therefore, after the BGP device filters the current routing information that needs to be sent to the target neighbor device, the filtered current routing information to be sent is added to the list to be sent, and then the current routing information in the list to be sent can be packed and sent to the target neighbor device. Specifically, when the current mapping relationship is not matched with the pre-stored mapping relationship, the current routing information may be added to a to-be-sent list, and the current routing information in the to-be-sent list is packed into an update message, and the BGP device sends the packed update message to the target neighbor device without sending each piece of routing information one by one, so as to improve the efficiency of sending the routing information.
