The present embodiment also provides a kind of message subscribing control method applied to network system 10 shown in Fig. 1, in this implementation
In example, it regard one of network equipment 100 shown in FIG. 1 as first network equipment, and will communicate with the first network equipment
And other network equipments 100 that message can be sent to first network equipment are used as second network equipment, referring to figure 2., below
Each step of method provided in this embodiment is explained in detail.
Step S110, controller are retrieved as the message subscribing strategy of first network device configuration and are sent to first network setting
Standby, which includes the message that first network equipment needs to obtain from second network equipment.
Step S120, first network equipment receive message subscribing strategy from controller, and tactful to the second net according to subscribing to
Network equipment sends message subscribing notice, and message subscribing notice includes that the first network equipment needs to obtain from second network equipment
Message.
In the present embodiment, message subscribing strategy can be packaged in BGP (Border Gateway by controller
Protocol, Border Gateway Protocol) message or ISIS (Intermediate System to Intermediate
System, Intermediate System-to-Intermediate System) protocol message specific fields in be sent to first network equipment.
Step S130, second network equipment notify to send corresponding message to first network equipment according to message subscribing.
In the present embodiment, administrator can carry out configuration operation according to the planning of network system on the controller, in advance
Corresponding role or function are specified for each network equipment.

The data forwarding of other related network devices impacts.
For example, it may include on second network equipment before some IP that first network equipment, which needs the communications status event subscribed to,
Whether effectively to sew route next jump state (IP Prefix NextHop Status).If first network equipment is set from the second network
The standby communications status subscribed to knows in the routing that second network equipment saves that the next-hop of some routing is at second equipment
Can not participate in forwarding (such as the next-hop the corresponding ARP entry in address be deleted or next-hop exit port caching gather around
Plug), then first network equipment does not allow message relevant to the next-hop being forwarded to second network equipment.
For another example first network equipment can subscribe to the state of some three layer interface of network of second network equipment (such as
Whether whether available or VXLAN interface can be used vsi-interface), to know respective subnet on second network equipment
Gateway status, to judge whether the message for destination host under the subnet needs to be implemented IP forwarding, if subnet gateway state is
Unavailable (it is down that such as vsi-interface state, which is down or VXLAN Interface status), then will not needle in first network equipment
Carrying out IP forwarding to the host IP address in the subnet also can not be normal because even message is forwarded to second network equipment
Forwarding results even in the CPU that message impacts second network equipment, causes unnecessary resource cost.
Correspondingly, in order to subscribe to some specific communications status events, first network equipment is sent in message subscribing notice
It may include event subscription content field, event subscription content field is used to record the communication for needing to obtain from second network equipment

Message so that second network equipment sends corresponding message according to unsubscribing notice and cancel to first network equipment.
Based on above-mentioned design, also a kind of possible message subscribing notice of the present embodiment or the format for unsubscribing notice are asked
Referring to Fig. 3, in the present embodiment, subscription operation field can be used for distinguishing message subscribing notice and unsubscribe notice.Address
It subscribes to quantity or event subscription amount field is used to identify the quantity for needing the content item subscribed to or unsubscribed.It subscribes to address
Content field and event subscription content field are used to record the content that actual requirement is subscribed to or to be unsubscribed.For example, address is ordered
Readding content 1 can be that MAC/IP Advertisement Route message is specified to require received AS (Autonomous
System, autonomous system) number, address style etc., it can also only include MAC Address or host IP address.For another example event
Subscribed content 1, which can be in certain communications status, such as event on second network equipment, can recorde certain in subscribed content 1
A VNI, to indicate to need to pay close attention to the subnet state of the VNI on second network equipment；Again for example in event in subscribed content 1
It can recorde some RD (Route Distinguisher, Route Distinguisher), need to pay close attention on second network equipment with instruction
Some EVPN or some subnet.
In the present embodiment, first network equipment can by BGP Notification (BGP notice) message or
Link State Packet (link state packet) message of ISIS agreement is issued above-mentioned message subscribing notice or is unsubscribed logical
Know.
In step S140, second network equipment receives the message subscribing notice of first network equipment transmission or cancels and orders
After readding notice, it can recorde first network equipment and need to subscribe to or unsubscribe rear remaining subscribed content.For example, if first
In the message subscribing notice that the network equipment is sent, simply requests and subscribe to host ip routing, the then BGP that second network equipment is sent
It only can include host in NLRI (Network Layer Reachability Information, Network Layer Reachable Information) message
IP routing, and MAC Address will not be then included in MAC/IP Advertisement Route message.
Wherein, in the present embodiment, for address message, the effect of all message is not subscribed to and subscribed to first network equipment
It is identical.For example, if first network equipment is not supported to subscribe to function message subscribing notice will not be sent to second network equipment, then
The subscribed content of the first network device requirement will not be recorded in second network equipment, and second network equipment can be according to existing procedure
All NLRI information is sent to the first network equipment.If second network equipment is not supported to subscribe to function, it will not handle and come from
The message subscribing message of first network equipment, second network equipment still can be sent out according to existing procedure to first network equipment
All NLRI message are sent, but not send any communications status event.
And for communications status event, it is necessary to it is that first network equipment has advertised and needs to subscribe to, the just meeting of second network equipment
Corresponding communications status event is sent, otherwise second network equipment will not send any communications status event.
