Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for routing and publishing, and a network device.
Background
In a multi-campus scenario, a networking environment of a single campus is usually a three-tier networking, and the three-tier networking includes: a core layer, a convergence layer and an access layer; as shown in fig. 1, fig. 1 is a networking architecture of multiple parks, where a boundary device of each park is typically a Spine device of a core layer (in a single Leaf scenario, a boundary device is typically a Leaf device of a convergence layer). In fig. 1, VXLAN (eXtensible Virtual local area network) -DCI (Data Center Interconnection tunnel) is established between the various parks through a border device Spine, and the tunnel adopts a VXLAN encapsulation format. The border device Spine establishes a VXLAN tunnel with Leaf devices inside the campus. After receiving the message from the VXLAN tunnel or VXLAN-DCI tunnel, the border device Spine releases VXLAN encapsulation, re-performs VXLAN encapsulation on the message according to the destination IP address, and forwards the message to the VXLAN-DCI tunnel or VXLAN tunnel, thereby realizing the intercommunication between the cross-parks.
In the actual network service of the user, a micro-segmentation (micro-segmentation) scheme is introduced, and each micro-segmentation is a group which is divided into network termination points (such as one or a group of servers) according to a certain principle. Each micro-segment has a globally unique identification ID.
In an EVPN (Ethernet Virtual Private Network) Network, the authority control is based on a micro-segment flow control policy, and is implemented in the current campus by using policy routing configuration, so that a corresponding relationship between a micro-segment ID and a member IP address is required. Under the scene of multiple parks, the corresponding relation between the ID of the micro-segment of the park and the IP address of the member can be synchronously distributed to an opposite-end park through the expanded community attribute of the MAC/IP release route of the EVPN (Border Gateway Protocol), and after receiving the routing information, the opposite-end park synchronizes to other Leaf devices in the park through IBGP (Internal Border Gateway Protocol).
Due to the fact that the number of online users in a multi-park scene is huge, routing information is too much, routing table items in Leaf equipment cannot bear the routing information, and once the capacity of the routing table items of the Leaf equipment is insufficient, normal online of the users accessing the Leaf equipment is affected.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
Before describing the methods provided herein, a brief introduction will be made to some concepts designed in this application.
Micro-segmentation: (Microsegment), also called fine packet based security isolation, essentially performs flow control based on group identification after grouping packets. For example, servers in a data center network are grouped according to a certain principle, and then a flow control strategy is deployed based on the grouping, so that the purposes of simplifying operation and maintenance and managing security are achieved. An IP address and a VLAN (Virtual Local Area Network) identifier may be used as a micro-segment, and any method in the prior art may be used as the micro-segment specifically for which identifier is used, which is not described in detail in this embodiment.
Routing strategy: the routing strategy is a mechanism for carrying out routing forwarding according to a strategy formulated by a user. The policy routing may perform a specified operation, such as setting a next hop, an outgoing interface, a default next hop, a default outgoing interface, and the like of the packet, for a condition that a certain condition is satisfied, such as an Access Control List (ACL) rule, a packet length, and the like.
In view of the problems in the prior art, this embodiment provides a route publishing method, where when a network device of a core layer receives a route published by a network device of another autonomous system, routing information meeting conditions is no longer published to an access device in an autonomous domain where the network device of the core layer is located by matching a routing policy, so that route learning between two isolated autonomous systems can be suppressed, consumption of routing table entries of the access device is reduced, and the number of users who come online through the boundary device can be increased.
Fig. 2 is a schematic flow chart of the route distribution method provided in this embodiment, and as shown in fig. 2, the route distribution method may be applied to a network device in a core layer in an autonomous system. In order to better describe the method provided by the present embodiment, the method is described in the present embodiment by taking the network architecture shown in fig. 1 as an example, but it should be understood that the method provided by the present embodiment is not limited to be applied only to the network architecture shown in fig. 1. For example, the devices of the core layer in fig. 1 may or may not be stacked devices. The network device of the core layer may also be connected to an AC (Access Controller). The autonomous system in this embodiment may be a campus as an autonomous system, or may be a computer room as an autonomous system. This embodiment takes AS an example that network devices in one campus are assigned the same AS (Autonomous System) number in the network architecture shown in fig. 1. In fig. 1, a campus 1 is referred to AS a first autonomous system, an AS number is referred to AS200, a campus 2 is referred to AS a second autonomous system, and an AS number is referred to AS100, a network device in which a core layer exists in a stacked manner in the first autonomous system (campus 1) is referred to AS a first network device, and a core layer network device in any fabric (in this example, fabric 2) in the second autonomous system (campus 2) is referred to AS a second network device. Specifically, the route publishing method provided in this embodiment includes:
In step 203, the matching routing policy may perform matching according to the AS number, and instruct the network device to execute a corresponding action by using an action item (action), for example, the action item is dense, that is, instruct the access device to suppress learning of the AS number not belonging to the first autonomous system, and then the first network device does not synchronize the routing with the access device in the first autonomous system.
Of course, the matching routing policy may also determine a corresponding micro-segment according to the IP address, or according to the source IP address (and/or the destination IP address), determine a corresponding action item according to the micro-segment, and so on. The matching items of the specific routing strategies can be set according to actual needs.
In the prior art, if there are two isolated autonomous systems, if 1000 users are on-line respectively, and at this time, if the two autonomous systems are interconnected, the two autonomous systems will learn the routing mutually, and the access device will learn the routing information of all the users in the two autonomous systems, and generate 2000 routing table entries. At this time, if the number of the routing table entries of the access device reaches the upper limit, the access device can no longer learn the network segment routing and the host routing of the newly on-line user. At this time, all connected parks can be on-line by 2000 users at most.
After the suppression of the route learning is configured, when the network equipment of the core layer synchronizes the route information to the access equipment, the route information from other autonomous systems is not synchronized any more, so that the consumption of the route table entry of the access equipment is reduced. The number of online users of all connected parks can be much larger than 2000, and the number of online users depends on the total number of routing table entries of core layer network equipment.
In a first optional implementation manner, the routing information further includes an IP address, and if the IP address is a host route, correspondingly, the specific implementation manner of step 203 is as follows: and if the route strategy matched according to the IP address in the route information indicates that the learning of the IP address with the host route type is inhibited, the first network equipment of the core layer does not synchronize the route information with the access equipment in the first autonomous system.
In a second optional implementation manner, the routing information may further include a micro segment, and correspondingly, in step 203, if the routing policy matched according to the micro segment indicates that learning of the AS number of the second autonomous system is suppressed, the first network device in the core layer does not synchronize the routing information with the access device in the first autonomous system, including:
and matching the routing strategy according to the differential section, wherein if the AS100 of the second autonomous system is indicated to be inhibited according to the matched routing strategy, the first network equipment of the core layer does not synchronize routing information with the access equipment in the first autonomous system.
In a third optional implementation manner, in step 203, if the indication indicates, according to the matched routing policy, to suppress learning of the AS number of the second autonomous system, the step of not synchronizing the routing information with the access device in the first autonomous system by the first network device of the core layer specifically includes:
determining a differential section corresponding to the IP address according to the IP address in the routing information;
and matching the routing strategy according to the differential segment, wherein if the AS100 is indicated to inhibit the learning of the AS according to the matched routing strategy, the first network equipment of the core layer does not synchronize the routing information with the access equipment in the first autonomous system.
Certainly, when the routing policy is matched, the corresponding action item is executed only when the AS number, the IP address and the differential segment are all matched with the routing policy.
To summarize the above implementation manner, in this embodiment, the host routing and the AS number of the autonomous system (that is, not the first autonomous system) are suppressed, that is, the routing information is not synchronized with the access device in the first autonomous system, so that the number of routing table entries of the access device is reduced.
Fig. 3 shows that, on the basis that a BGP peer is established between core-layer network device spine1 and Leaf1 in campus 1, when a BGP route is published to Leaf1 on core-layer device spine1 in campus 1, a routing policy with certain conditions is matched, and routing information that meets the conditions will not be published to Leaf 1. The routing information meeting the condition can be host routing or AS numbers of other parks contained in the As-path attribute, so that the filtering of the host routing or the routing corresponding to the AS numbers of other parks can be realized.
As shown in fig. 3, Spine1 of campus 1 publishes the route of campus 1 to Spine2 of campus 2, the As-path in the route attribute is 200, Spine2 of campus 2 publishes the route of campus 2 to Spine1 of campus 1, and the As-path in the route attribute is 100.
Spine2 of campus 2 learns the route sent to campus 1 and issues the route to Leaf3 under the direction of the routing policy. Due to the restriction of the routing strategy, the Leaf3 only learns the host route with As-path of 100, but not the route with As-path of 200 issued by the campus 1.
As shown in fig. 3, IP addresses 1.1.1.1 and 1.1.1.2 are IP addresses of terminals on line in the campus 1, and IP addresses 1.1.1.3 and 1.1.1.4 are IP addresses of terminals newly on line in the campus 2, and Leaf3 in the campus 2 can learn host routing information whose IP addresses are IP addresses 1.1.1.3 and 1.1.1.4 of the same campus, but cannot learn host routing information whose IP addresses are IP addresses 1.1.1.1 and 1.1.1.2 of other campuses 1.
In an alternative implementation manner, in the scenario of differential segment, the AS number of the extended community attribute in the routing information may be filtered by using a routing policy, so AS to reduce consumption of routing resources on the access device leaf.
On the basis of the foregoing embodiments, as shown in fig. 4, this embodiment further provides a route distribution apparatus, which may be disposed on a first network device in a core layer of a first autonomous system, where the apparatus includes: a receiving module 401, a synchronization module 402, and a policy matching module 403;
the receiving module 401 is configured to receive routing information issued by a second network device in a second autonomous system, where the routing information includes an AS number of the second autonomous system;
the synchronization module 402 is configured to, when the policy matching module 403 indicates, according to the matched routing policy, that the access device in the first autonomous system is inhibited from learning the AS number of the second autonomous system, the synchronization module 402 does not synchronize the routing information with the access device in the first autonomous system.
Optionally, the synchronizing module 402 is further configured to, under the condition that the routing information further includes an IP address, if the routing policy matched by the IP address in the policy matching module 403 indicates that the learning of the IP address of which the IP address is the host routing type is suppressed, the synchronizing module 402 does not synchronize the routing information with the access device in the first autonomous system.
Optionally, the synchronizing module 402 is further configured to, in a case that the routing information further includes micro segments, match a routing policy by the policy matching module 403 according to the micro segments, and if the matching routing policy indicates that learning of the AS number of the second autonomous system by the access device is inhibited, the synchronizing module 403 does not synchronize the routing information with the access device in the first autonomous system.
