Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
It should be noted that：Similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.Meanwhile the application's
In description, term " first ", " second " etc. are only used for distinguishing description, are not understood to indicate or imply relative importance.
Current VXLAN gateway technique is divided into two kinds：Centralized gateway and distributed network gate, centralized gateway refer to all
Gateway concentration is deployed in a VTEP equipment, this VTEP equipment is usually located at the convergence layer of network topology, if but three layers
Flow all concentrates on carrying out routing forwarding in gateway, is easy to appear forwarding bottleneck；Distributed network gate is to solve to collect
The forwarding performance problem of Chinese style gateway, currently it is more widely used that distributed network gate technology, distributed network gate are by gateway portion
Administration is on access VTEP, and all access VTEP dispose identical gateway.
Fig. 1 is please referred to, Fig. 1 is a kind of structural block diagram of VXLAN network system provided by the embodiments of the present application, shown in Fig. 1
It is deployed in the structural schematic diagram in VXLAN network for distributed network gate, which includes aggregation gateway, access net
Close and the network equipment, for example, as shown in fig. 1, aggregation gateway includes P1 and P2, access gateway include VTEP-1, VTEP-2,
VTEP-3......VTEP-n, the network equipment include equipment 11, equipment 12, equipment 21, equipment 22...... equipment n, all
Access gateway is both connected on aggregation gateway P1 and P2, and multiple network equipments are connected under each access gateway, and the network equipment can
With server or user terminal, the network equipment connected under each access gateway may belong to different network segments, may belong to phase
Same network segment, for example, equipment 11 and equipment 12 are all connected on access gateway VTEP-1, then equipment 11 and equipment 12 can belong to same
A network segment, or belong to different network segments, equipment 21 and equipment 22 are all connected with access gateway VTEP-2, and equipment 11 and equipment 21
It may belong to the same network segment, equipment 12 and equipment 22 may belong to the same network segment.
In the prior art, access gateway conciliates encapsulation process for realizing the encapsulation of VXLAN message, and aggregation gateway is only used for
IP forwards transparent transmission, is not involved in VXLAN forwarding logic.
And it is as described in Figure 1, if three laminar flows are supported between the network equipment of different segment there are two the network equipment of network segment
Measure intercommunication, wherein the network equipment 11 and the network equipment 21 can be identical network segment equipment, and the network equipment 12 and the network equipment 22 can
Think phase same network segment equipment, the network equipment 11 and the network equipment 12 can be different segment equipment, can dispose in VXLAN network
Multiple network segments are not limited only to two, are only example here.
Each access gateway disposes the gateway there are two network segment respectively, and gateway IP, mask-length, gateway interface MAC
Location is all identical, i.e., all access gatewaies are distributed network gate.
Access gateway can obtain this according to address resolution protocol (Address Resolution Protocol, abbreviation ARP)
The Host routes for the network equipment that ground is directly accessed, and respectively obtained by BGP-EVPN agreement to the notice of other access gatewaies
The Host routes of the network equipment acquired from other access gateway are locally generated corresponding host by content, access gateway
The routing outlet of routing, Host routes is other access gateway.
For example, the Host routes of four network equipments can be acquired on VTEP-1：By straight under local direct-connected gateway interface
It obtains to obtain the Host routes of the network equipment 11；By the host for directly obtaining the network equipment 12 under local direct-connected gateway interface
Routing；By acquiring the Host routes of the network equipment 21 from VTEP-2, locally needs to generate corresponding Host routes, route out
Mouth is VTEP-2；By acquiring the Host routes of the network equipment 22 from VTEP-2, locally need to generate corresponding Host routes,
Routing outlet is VTEP-2.
Wherein, BGP-EVPN agreement is the control protocol of the VXLAN based on IETF RFC 7342, and BGP-EVPN agreement is
End host after long-range VTEP provides control plane and obtains function, can be handed over by BGP-EVPN agreement between gateway
It changes and obtains respective IP address.
When three laminar flow amounts forward, three-layer routing is directly searched in access gateway, inquires corresponding Host routes, thus
The forwarding of message is carried out, if access gateway is searched less than Host routes, ARP acquisition can be triggered, i.e. the access gateway is actively sent out
ARP request message is sent, the Target IP of ARP request message is the destination IP of message, is corresponded to so that triggering acquires the destination IP
Host routes, such as access gateway VTEP-1 receives the message that equipment 11 is sent to equipment 21, then searches local routing
In whether have the Host routes of equipment 21, if so, then forward the packet to access gateway VTEP-2, then access gateway VTEP-2
It is forwarded to equipment 21 again, if not finding the Host routes of equipment 21, access gateway VTEP-1 active transmission ARP request report
Text, each aggregation gateway and each access gateway can receive the ARP request message, as access gateway VTEP-2 receives this
Equipment 21 and equipment 22 are sent to after ARP request message, equipment 21 obtains the ground that destination address is oneself from ARP request message
Location then sends an arp reply message, then access gateway VTEP-2 learns the host to equipment 21 by the arp reply message
Routing, and notify Host routes by BGP-EVPN agreement to give access gateway VTEP-1, so that access gateway VTEP-1 is obtained
To the Host routes of equipment 21, to carry out subsequent message forwarding.
According to the technical principle of distributed network gate, accesses VETP and needs to acquire the all-network equipment in whole network,
I.e. other than the network equipment that local user to be acquired flanks, also to acquire the network accessed under other access gatewaies and set
It is standby, and the network equipment enormous amount in entire VXLAN network, and since access layer equipment is large number of, typically portion
Administration's box-shaped device of low and middle-end, the capacity of software and hardware list item is limited, is easy to appear list item off-capacity, and then cause to lose
Packet, while access gateway needs to complete actively to obtain the movement of ARP, has aggravated to equipment CPU's after the failure of route querying table
Burden.
Compared with access gateway, aggregation gateway generally has bigger chip routing list capacity, more powerful CPU processing energy
Power, but these resources advantages are not applied in the VXLAN distributed network Central Shanxi Plain.
So to solve the above-mentioned problems, the embodiment of the present application provides a kind of message forwarding method.
Defect present in the above scheme in the prior art, is that inventor is obtaining after practicing and carefully studying
As a result, therefore, the solution that the discovery procedure of the above problem and hereinafter the embodiment of the present application are proposed regarding to the issue above
Scheme all should be the contribution that inventor makes the application during the application.
Referring to figure 2., Fig. 2 is a kind of flow chart of message forwarding method provided by the embodiments of the present application, this method application
In VXLAN network system shown in FIG. 1, described method includes following steps：
Step S110：Aggregation gateway receives the data message that the first access gateway is sent.
Step S120：The aggregation gateway sends out the data message according to the Host routes of second equipment of acquisition
It send to second equipment.
In combination with Fig. 1, the embodiment of the present application is illustrated so that the quantity of aggregation gateway is one as an example, and aggregation gateway can be with
It is convergence layer gateway for P1, P1 and the P2 in Fig. 1, can be described as aggregation gateway, VTEP-1, VTEP-2...VTEP-n is access
Layer gateway, can be described as access gateway.
Aggregation gateway can externally notice itself by protocol interaction and be used as " aggregation gateway ", for example, can pass through BGP-
EVPN agreement sends notification packet, and aggregation gateway tells other when sending BGP-EVPN protocol massages to other access gatewaies
Access gateway increases a default route, and the next-hop of the routing is aggregation gateway itself.
Aggregation gateway configures the gateway interface of all network segments, installs gateway interface in forwarding table as distributed network gate
Direct-connected routing.
It is also configured with BGP-EVPN agreement in each aggregation gateway, host can be acquired from all access gatewaies automatically
Routing.
Access gateway undertakes the role of common distributed network gate, as distributed network gate, need to configure all network segments
Gateway interface, but not in route forwarding table install gateway interface direct-connected routing.Because message carries out meeting when three layers of forwarding
According to the destination IP of message search route forwarding table, when table look-up hit direct-connected routing when, message will not forward, but trigger
Access gateway sends the ARP request destination IP, so the purpose for not installing direct-connected routing in access gateway is in order to avoid connecing
Function Access Gateway sends ARP message and goes to obtain Host routes, to mitigate the CPU pressure of access gateway.
In the embodiment of the present application, the data message is the first equipment for connecting with first access gateway to second
The message that second equipment of access gateway connection is sent, i.e. the first equipment are connect with the first access gateway, the second equipment and second
Access gateway connection, the first access gateway are connect with the aggregation gateway with the second access gateway.First equipment is set with second
Standby to may belong to different network segments, for example, as shown in fig. 1, the first access gateway is VTEP-1, the first equipment is equipment 11,
Second access gateway is VTEP-2, and the second equipment is equipment 22, aggregation gateway P1, if the first equipment 11 is sent out to the second equipment 22
Data message is sent, then data message is first sent to the first access gateway VTEP-1, the first access gateway VTEP- by the first equipment 11
1 after receiving data message, search routing table, if in routing table not with the matched host road of the IP address of the second equipment 22
By that can not trigger ARP message and send to obtain the second equipment 22 since the first access gateway VTEP-1 is fitted without direct-connected routing
Host routes, so data message is sent to aggregation gateway according to above-mentioned default route by the first access gateway VTEP-1
P1。
Wherein, aggregation gateway P1 is when it oneself is aggregation gateway identity that other gateways into VXLAN network system, which are noticed,
BGP-EVPN protocol massages can be sent to other gateways to be noticed, for example, aggregation gateway PI can be to the first access gateway
VTEP-1 and the second access gateway VTEP-2 sends notification packet, the IP of aggregation gateway P1 is carried in the notification packet
Location, then the first access gateway VTEP-1 and the second access gateway VTEP-2 are after receiving the notification packet, from notification packet
The IP address of the aggregation gateway P1 is obtained, then the first access gateway VTEP-1 and the second access gateway VTEP-2 is by the convergence
The IP address of gateway P1 is added in respective routing table as the destination address in above-mentioned default route.
So the first access gateway VTEP-1 is to aggregation gateway P1 when sending datagram, it can be according to default road
By sending datagram to aggregation gateway P1.
Referring to figure 3., Fig. 3 is the sub-step flow chart of step S120 provided by the embodiments of the present application, and step S120 includes：
Step S121：The aggregation gateway obtains the IP address of second equipment from the data message.
Step S122：In the routing table of the aggregation gateway not with the matched host of IP address of second equipment
When routing, the aggregation gateway sends ARP request message to second access gateway.
Step S123：The aggregation gateway receives second access gateway and obtains according to the IP address of second equipment
Obtain the notice message sent after the Host routes of second equipment.
Step S124：The Host routes of second equipment are added in the routing table by the aggregation gateway, described
The data message is sent to second equipment according to the Host routes of second equipment by aggregation gateway.
The IP of second equipment 22 is carried in the data message sent due to the first equipment 11 to the second equipment 22
Location, so, the aggregation gateway P1 is after receiving data message, the IP of the second equipment 22 is obtained from the data message
Location the matched Host routes of IP address whether having in the routing table of aggregation gateway P1 with second equipment 22 is searched, in institute
When stating in routing table not Host routes matched with the IP address of second equipment 22, the aggregation gateway P1 is to described
Two access gateway VTEP-2 send ARP request message, and the ARP request message carries the IP address of second equipment 22.
It should be noted that the data message that the first equipment 11 is sent to the first access gateway VTEP-1 is also needed by first
Access gateway VTEP-1 is carrying out being sent to aggregation gateway P1 after being packaged into VXLAN data message, and aggregation gateway P1 is received
It is decapsulated to obtain original data message after to VXLAN data message.
Aggregation gateway P1 also needs ARP request message being packaged into VXLAN data before sending ARP request message
It is sent after message, the second access gateway VTEP-2 carries out decapsulation acquisition after receiving the VXLAN data message as a result,
ARP request message.
Since ARP request message can be broadcasting packet, so, the first access gateway VTEP-1 and the second access gateway
VTEP-2 can receive the ARP request message, because in ARP request message including the IP address of the second equipment 22, then
One access gateway VTEP-1 is sent to the network equipment being attached thereto receiving the ARP request message, in each network equipment
The IP address of the second equipment 22 is obtained from ARP request message, discovery is not the address of oneself, then abandons the ARP request report
Text.
The ARP request message is sent to by the second access gateway VTEP-2 after receiving the ARP request message to be connected therewith
The each network equipment connect, if the second equipment 22 obtains target from ARP request message after receiving the ARP request message
Address is the address of oneself, then the second equipment 22 sends arp reply message, the second access gateway to the second access gateway VTEP-2
VTEP-2 receives the arp reply message to acquire the Host routes of the second equipment 22, then the second access gateway VTEP-
2 send notice message to aggregation gateway P1, and the Host routes of second equipment are carried in the notice message, and notice obtains
The Host routes of the second equipment 22 arrived, so that aggregation networks P1 obtains the Host routes of the second equipment from the notice message.
Second access gateway VTEP-2 can be sent to aggregation gateway P1 by BGP-EVPN agreement and be notified, specific implementation is exactly
In BGP-EVPN protocol massages, increase the Host routes of second equipment 22, routing outlet is the second access gateway VTEP-
2, then other gateways can add the Host routes of the second equipment 22 when receiving the message in the routing table of oneself.
Aggregation gateway P1 receives the notice message that the second access gateway VTEP-2 uses BGP-EVPN agreement to send, and obtains
