The step of, improve the efficiency and flexibility for establishing connection tunnel.
It should be noted that the first business network edge device obtain connection set label after, can be according to the connection
Set label establishes the connection tunnel between the first business network edge device and the second business network edge device.Wherein, by
Different parameters for tunnel values can be corresponded in different business network edge devices, before establishing connection tunnel, it can be determined that
First parameters for tunnel value of the first business network edge device whether the second parameters for tunnel with the second business network edge device
Value matches, to establish connection tunnel according to judging result.
If the first parameters for tunnel value is matched with the second parameters for tunnel value, according to connection set label, the first business is established
Connection tunnel between network edge device and the second business network edge device.
For example, the first business network edge device may determine that the local in the first parameters for tunnel value marks whether and second
Distal marker in parameters for tunnel value is consistent, obtains the first judging result, and judges the distal marker in the first parameters for tunnel value
It is whether consistent with the local label in the second parameters for tunnel value, obtain the second judging result.
When the first judging result indicates consistent with the second judging result, then illustrate the first parameters for tunnel value and the second tunnel
Parameter value matching in road can establish the first business network edge device according to connection set label and set with the second business network edge

Edge device is the business network edge device that connection tunnel is currently established with the first business network edge device.
Moreover, access parameter is that the second business network edge device determines that user network boundary device meets transition condition
When, it carries out being added what update obtained by pre-set accumu-late parameter value, wherein accumu-late parameter value is positive integer.
Specifically, the available pre-recorded preset access parameter of the first business network edge device, and this is preset
Access parameter is compared with the access parameter in routing iinformation, judges whether the parameter value of access parameter is greater than preset access ginseng
Several parameter values.If the parameter value of access parameter is greater than the parameter value of preset access parameter, illustrate that user network boundary device is sent out
Migration has been given birth to, has needed to re-establish connection tunnel, then can establish the first business network edge device and the second business network side
Connection tunnel between edge equipment.
For example, when user network boundary device is when accessing third business network edge device, the first business network edge
The routing iinformation that equipment can be sent according to third business network edge device, establishes the first business network edge device and third
Connection tunnel between business network edge device, then can will third business network edge device send routing iinformation in
Access parameter is as preset access parameter, and using third business network edge device as first business network edge device.

Access parameter is set, then can interrupt the connection tunnel between the first business network edge device and third business network edge device
Road, and establish the connection tunnel between the first business network edge device and the second business network edge device.
It should be noted that if record does not have pre-set preset access ginseng in the first business network edge device
Number, then can be determined as 0 for the parameter value of preset access parameter, without between more preset access parameter and access parameter
Size relation, but establish the connection tunnel between the first business network edge device and the second business network edge device.
In addition, the connection tunnel established between the first business network edge device and the second business network edge device it
Afterwards, the preset access parameter of record can be updated, is that is to say, delete pre-recorded preset access parameter, and by
The access parameter in routing iinformation that two business network edge devices are sent is as new preset access parameter, so as to the second business
Network edge device can generate group attribute information according to updated preset access parameter, alternatively, establishing connection tunnel.
Therefore, the parameter value of preset access parameter can be replaced with the ginseng of access parameter by the first business network edge device
Numerical value.
For example, the pre-recorded preset access parameter of the first business network edge device is " 2 ", the second business network edge
The access parameter in routing iinformation that equipment is sent is " 3 ", then preset access parameter can be updated to " 3 ".
Fig. 3 is the flow diagram of the method for building up in the connection tunnel that another embodiment of the disclosure provides, and is applied to such as Fig. 1
