VSI, the first VSI configure the first tunnel VXLAN of relevant first VXLAN and the 2nd tunnel VXLAN for being associated with the first VXLAN.
Fig. 2 shows the flow charts of message forwarding method according to an embodiment of the invention.As shown in Fig. 2, the method comprising the steps of S21 is extremely
Step S24.
In the step s 21, tunnel switching command is received, tunnel switching command includes the mark and the first VXLAN of the first VSI
The mark in tunnel.
Wherein, tunnel switching command refers to the order switched over for the tunnel interface state to tunnel.Pass through tunnel
Switching command, which can be realized, switch the standby tunnel VXLAN as the main tunnel VXLAN, is thus configured in VSI and multiple is associated with VXLAN's
The tunnel VXLAN can be realized VTEP and neatly select the tunnel VXLAN for being used to be forwarded service message in VSI.
In one implementation, tunnel switching command is vxlan-tunnel switchover vsi vsi-name
tunnel tunnel-id.Wherein, vsi-name indicates the mark of VSI, and tunnel-id indicates the mark in the tunnel VXLAN.Pass through
The mark of VSI and the mark in the tunnel VXLAN can uniquely determine the tunnel VXLAN.Pass through the vsi- in tunnel switching command
Name and tunnel-id can uniquely determine the tunnel VXLAN.
In one implementation, if the tunnel interface for passing through the tunnel VXLAN determined vsi-name and tunnel-id
State is effective status, and the tunnel interface state in the corresponding standby tunnel VXLAN in the tunnel VXLAN is blocked state, then switches
Use the corresponding standby tunnel VXLAN in the tunnel VXLAN.
In step S22, according to the mark of the first VSI and the mark in the first tunnel VXLAN, obtain first in the first VSI

| Up (available mode) | It is | It is |
| Block (blocked state) | It is no | It is no |
| Down (invalid state) | It is no | It is no |
Wherein, if the tunnel interface state in the tunnel VXLAN is effective status in VSI, VSI can pass through the VXLAN
The interface in tunnel sends and receives service message.If the tunnel interface state in the tunnel VXLAN is blocked state, VSI in VSI
Service message can not be sent and received by the interface in the tunnel VXLAN.If the tunnel interface in the tunnel VXLAN in VSI
State is invalid state, then VSI can not send and receive service message by the interface in the tunnel VXLAN.
In step S23, if the tunnel interface state in the first tunnel VXLAN is effective status in the first VSI, and second
The tunnel interface state in the tunnel VXLAN is blocked state, then cuts the tunnel interface state in the first tunnel VXLAN in the first VSI
It is changed to blocked state, and the tunnel interface state in the 2nd tunnel VXLAN is switched to effective status.
As an example, as shown in Figure 1, configuring VSI1 on VTEP1, VSI1 configure Tunnel1 and Tunnel2 with
VXLAN10 association.VM1 accesses VSI1 by AC.If the tunnel interface state of Tunnel1 is effective status in VSI1,
Tunnel1 is the main tunnel VXLAN, and Tunnel2 is the standby tunnel VXLAN.The tunnel interface state of Tunnel2 is blocked state.Such as
It is Tunnel1 with the VM2 exit port for carrying out communication interaction in VTEP1 in the forwarding table of stored VSI1 shown in table 2.
As shown in Figure 1, the process that VM1 sends service message to VM2 is as follows: VTEP1 receives the business report of VM1 transmission
Text judges that the service message belongs to VSI1 (VXLAN10), searches the forwarding table of VSI1, obtains carrying out going out for communication interaction with VM2
Port is Tunnel1.Then VTEP1 encapsulates to obtain VXLAN message 1 to service message progress VXLAN, and VXLAN message 1 is led to
The interface for crossing Tunnel1 issues.
Table 2
VTEP1 receives tunnel switching command vxlan-tunnel switchover vsi1 tunnel1.Such as Fig. 1 institute
Show, the tunnel interface state that VTEP1 obtains Tunnel1 in VSI1 is effective status, and the tunnel for obtaining Tunnel2 in VSI1 connects
Mouth state is blocked state.The tunnel interface state of Tunnel1 and the tunnel interface state of Tunnel2 meet tunnel and cut in VSI1
Condition is changed, then the tunnel interface state of Tunnel1 in VSI1 is switched to blocked state from effective status by VTEP1, and by VSI1
The tunnel interface state of middle Tunnel2 is switched to effective status from blocked state.At this point, Tunnel2 is the main tunnel VXLAN,
Tunnel1 is the available standby tunnel VXLAN.
In step s 24, by the corresponding exit port of the first VSI in forwarding table stored in VTEP by the first VXLAN
The mark in tunnel is changed to the mark in the 2nd tunnel VXLAN.
The example of step S23 is accepted, as shown in table 3, after VTEP1 receives tunnel switching command, in VTEP1
In the forwarding table of stored VSI1, Tunnel2 is changed to by Tunnel1 with the VM2 exit port for carrying out communication interaction.
As shown in Figure 1, the process that VM1 sends service message to VM2 is as follows: VTEP1 receives the business report of VM1 transmission
Text judges that the service message belongs to VSI1 (VXLAN10), searches the forwarding table of VSI1, obtains carrying out going out for communication interaction with VM2
Port is Tunnel2.Then VTEP1 encapsulates to obtain VXLAN message 2 to service message progress VXLAN, and VXLAN message 2 is led to
The interface for crossing Tunnel1 issues.
Table 3
The message forwarding method of the embodiment of the present invention passes through tunnel in the tunnel VXLAN that VSI configures multiple association VXLAN
Switching command can be realized VTEP and neatly select the tunnel VXLAN for being used to be forwarded service message in VSI, to realize
To the reasonable employment in the tunnel VXLAN.For example, switching uses the biggish VXLAN tunnel of bandwidth when the quantity of service message increases
Road.
In one implementation, this method further include: if in the first VSI the first tunnel VXLAN tunnel interface shape
State is effective status, and the tunnel interface state in the 2nd tunnel VXLAN is invalid state, then keeps the first VXLAN in the first VSI
The tunnel interface state in tunnel and the tunnel interface state in the 2nd tunnel VXLAN are constant.
In one implementation, tunnel switching command is vxlan-tunnel switchover vsi vsi-name
tunnel tunnel-id.Wherein, vsi-name indicates the mark of VSI, and tunnel-id indicates the mark in the tunnel VXLAN.Pass through
Vsi-name and tunnel-id can uniquely determine the tunnel VXLAN.
In one implementation, if the tunnel interface for passing through the tunnel VXLAN determined vsi-name and tunnel-id
State is effective status, but the tunnel interface state in the corresponding standby tunnel VXLAN in the tunnel VXLAN is invalid state, then does not cut
It changes and uses the corresponding standby tunnel VXLAN in the tunnel VXLAN.
As an example, as shown in Figure 1, configuring VSI1 on VTEP1, VSI1 configure Tunnel1 and Tunnel2 with
VXLAN10 association.VM1 accesses VSI1 by AC.If the tunnel interface state of Tunnel1 is effective status in VSI1,
Tunnel1 is the main tunnel VXLAN, and Tunnel2 is the standby tunnel VXLAN.The tunnel interface state of Tunnel2 is invalid state.
VTEP1 receives tunnel switching command vxlan-tunnel switchover vsi1tunnel1.As shown in Figure 1,
The tunnel interface state that VTEP1 obtains Tunnel1 in VSI1 is effective status, and obtains the tunnel interface of Tunnel2 in VSI1
State is invalid state.The tunnel interface state of Tunnel1 and the tunnel interface state of Tunnel2 are unsatisfactory for tunnel and cut in VSI1
Condition is changed, then it is effective status that VTEP1, which keeps the tunnel interface state of Tunnel1 in VSI1,.At this point, Tunnel1 is main VXLAN
