The hierarchy of branch, wherein, as the nucleus equipment of VTEP1 and VTEP2, VTEP1 and VTEP2 is as RR1 for RR1 and RR2
With the branch equipment of RR2.
In general, under normal operating conditions, RR1 and RR2 respectively with itself branch equipment (i.e. VTEP1 and
VTEP2) setting up has Border Gateway Protocol (BGP) neighborhood.Assuming that RR1 there occurs restart, at this moment, RR1 and VTEP1 and VTEP2
Between bgp neighbor relation can successively experience and release and the process that re-establishes.After bgp neighbor relation is re-established, VTEP1
The all routes that respectively can have been stored itself with VTEP2 are sent to RR1, with these routes for RR1 storages is received, and
The forwarding of the data message for instructing itself to receive using these routes.Because RR1 obtains all from VTEP1 and VTEP2
Route needs certain duration, it is possible that situations below in a period of time after RR1 is restarted：Route is obtained in RR1
During, RR1 have received the data message from one of VTEP1 and VTEP2, but, RR1 also not from VTEP1 and
The other of VTEP2 places obtain the route needed for being forwarded to the data message, and so, RR1 will be unable to the datagram
Text is forwarded, therefore the data message can be dropped.
In order to avoid there is above mentioned problem, a setting duration and can be provided with advance in the prior art, in RR1 and set
Determine cost values, setting cost values are than larger.In setting duration after RR1 is restarted, the corresponding cost values of RR1 are the setting
Cost values, also, setting cost values are more than the corresponding cost values of RR2, therefore, after VTEP1 obtains data message, VTEP1
The preferred next-hop of meeting is forwarded for the route of RR2 to the data message.Although it can easily be seen that this mode can realize it is right
The successful forwarding of data message, but, operating personnel need to be pre-configured with RR1, operate and more bother, also,
The specific value of setting duration and setting cost values is difficult to hold.
In order to solve the problems, such as prior art, a kind of route sending method and device are the embodiment of the invention provides.

Referring to Fig. 2, a kind of flow chart of route sending method that the embodiment of the present invention is provided is shown in figure.Such as Fig. 2
Shown, the method may include steps of：
S201, after Router Reflector is restarted, obtains the bright of the first virtual expansible LAN endpoint of a tunnel VTEP transmissions
Thin route, wherein, a VTEP is any VTEP for having correspondence with route transmitter.
Wherein, the VTEP for having correspondence with Router Reflector includes：Using the Router Reflector as nucleus equipment institute
There is VTEP.
For Router Reflector, after it is restarted, its can again with using itself as nucleus equipment all VTEP
Set up bgp neighbor relation.After the bgp neighbor relation is successfully established, using the Router Reflector as nucleus equipment each
The detailed route that VTEP will currently have therein is sent to the Router Reflector, and the Router Reflector can then store institute
The detailed route for receiving.
Whether S202, judges itself to obtain all detailed route in a VTEP；If it is, S203 is performed, if
It is no, perform S204.
S203, sends to the 2nd VTEP and route, wherein, the 2nd VTEP is the VTEP for having correspondence with Router Reflector
In, remaining VTEP in addition to a VTEP；
S204, does not send to the 2nd VTEP and route.
It should be noted that Router Reflector judges whether itself obtains all detailed routing iinformation in a VTEP
Implement various informative, citing introduction is carried out below.
In a kind of specific embodiment of the embodiment of the present invention, the first virtual expansible LAN endpoint of a tunnel is obtained
Before the detailed route that VTEP sends, the method can also include：
After itself restarts, the notice message that a VTEP sends is obtained, wherein, carried in a VTEP in notice message
The bar number of the detailed route having；
Correspondingly, judge itself whether to obtain all detailed route in a VTEP, can include：
Judge whether article number of itself detailed route acquired, from a VTEP carries not less than in notice message
Bar number；
If it is, showing itself to have obtained all detailed route in a VTEP；
If it has not, showing itself not obtaining all detailed route in a VTEP.
Restart in Router Reflector, and and after setting up bgp neighbor relation with each VTEP itself with correspondence, with the road
Each VTEP for having correspondence from reflector can send notice message to the Router Reflector.So, according to the notice message, should
Router Reflector can be informed in when setting up bgp neighbor relation with each VTEP, the bar number of the detailed route having in the VTEP,
Bar number in the notice message that the Router Reflector can send each VTEP is stored.
Afterwards, each VTEP with the Router Reflector with correspondence can send detailed route to the Router Reflector.
During receiving the detailed route from each VTEP, the Router Reflector can respectively to the detailed route from each VTEP
Bar number is counted, and bar number in the notice message that the bar number of the detailed route from each VTEP is sent with the VTEP is carried out
Compare.Once the Router Reflector detects the bar number of the detailed route from a certain VTEP not less than the notice that the VTEP sends
Bar number in message, the Router Reflector it is determined that itself obtain all detailed route in the VTEP, next, the road
Follow-up S203 is carried out by reflector.If conversely, the Router Reflector detects the detailed route from a certain VTEP
Bar number less than the VTEP send notice message in bar number, then, the Router Reflector carries out follow-up S204.
It can easily be seen that through the above way, whether Router Reflector can easily judge itself obtain
All detailed routing iinformation in one VTEP.Certainly, whether Router Reflector judges itself to obtain all in a VTEP
The form that implements of detailed routing iinformation is not limited thereto, and can specifically be determined according to actual conditions, the present embodiment pair
This does not do any restriction.
With reference to Fig. 1, the specific implementation process of the present embodiment is illustrated with a specific example.

VTEP includes VTEP1 and VTEP2, and the VTEP for having correspondence with RR2 also includes VTEP1 and VTEP2.
Assuming that RR1 there occurs restart, next, RR1 can set up bgp neighbor relation with VTEP1 and VTEP2 again.
After RR1 and VTEP1 have re-established bgp neighbor relation, VTEP1 can send notice message, the notice report to RR1
The bar number of the current detailed route having in VTEP1 is carried in text, it is assumed that this number is 180.The notice report is sent in VTEP1
Wen Hou, VTEP1 start to send detailed route to RR1.
Similarly, after RR1 and VTEP2 have re-established bgp neighbor relation, VTEP2 can also send to RR1 and notify report
Text, carries the bar number of the current detailed route having in VTEP2, it is assumed that this number is 200 in the notice message.In VTEP2 hairs
After going out the notice message, VTEP2 starts to send detailed route to RR1.
For RR1, during the detailed route from VTEP1 and VTEP2 is obtained, RR1 can respectively to coming
Counted from the bar number of the detailed route of VTEP1 and VTEP2.Once the bar number of the detailed route from VTEP1 reaches 180
Bar, this explanation RR1 just obtains all detailed route in VTEP1, and now, RR1 starts to send route to VTEP2.
It is easily understood that before RR1 sends route to VTEP2, be there is no from RR1's due to VTEP2 at all
Route, therefore, the data message that VTEP2 will never be obtained is forwarded to RR1, but the data message is forwarded to RR2, it
Afterwards, can be successfully forwarded to the data message at VTEP1 by RR2.After RR1 sends route to VTEP2, because VTEP2 is obtained
Route from RR1, therefore, RR1 can normally obtain the data message from VTEP2, because RR1 has now successfully been obtained
The all detailed route from VTEP1 was obtained, therefore, the road of the forwarding that can instruct the data message is certainly existed in RR1
By the data message finally can be forwarded successfully.
In this programme, after Router Reflector is restarted, it can set up bgp neighbor relation with a VTEP, and obtain first
The detailed route that VTEP sends.During detailed route is obtained, whether the Router Reflector can judge itself to obtain the
All detailed route in one VTEP.If it is judged that being yes, the Router Reflector will send to the 2nd VTEP and route；Such as
Fruit judged result is no, and the Router Reflector will not send to the 2nd VTEP and route.
It can easily be seen that before Router Reflector sends route to the 2nd VTEP, because the 2nd VTEP there is no at all
Route from the Router Reflector, therefore, the data message that the 2nd VTEP will never be obtained turns to the Router Reflector
Hair, but the data message is forwarded to remaining Router Reflector, to realize the data by remaining Router Reflector
The successful forwarding of message.After Router Reflector sends route to the 2nd VTEP, because the 2nd VTEP is obtained from the road
By the route of reflector, therefore, the Router Reflector can normally obtain the data message from the 2nd VTEP, due to the route
Reflector now have successfully been obtained all detailed route from a VTEP, therefore, necessarily deposited in the Router Reflector
In the route of the forwarding that can instruct the data message, the data message finally can be forwarded successfully.
It can be seen that, in this programme, operating personnel set duration and setting cost values without being pre-configured with Router Reflector,
After Router Reflector is restarted, sent by the delay routeing, this programme easily realizes Router Reflector to data
The successful forwarding of message, and then efficiently avoid the loss of data message.
