Such as, the first interface that interface index is N is connected with the second interface that interface index is N+1, by interface index is N+1 the
One interface is connected with the second interface that interface index is N+2.Wherein, the first interface being connected, second interface are configured
For the IP address of phase same network segment, the first interface being not connected with, second interface are configured to the IP address of different segment.
Step S220 is based on the preset path information, the first network equipment 20 and second network equipment 30
The test data packet is mutually forwarded in the test path.
In the present embodiment, first network equipment 20 and second network equipment 30 can surveyed according to preset path information
Try mutual transmitted test data packet in path.
For example, step 220 may include:
The first network equipment 20 determines in the multiple first interface current according to the preset path information
First output interface；
The test data packet is sent to described second by first output interface by the first network equipment 20
The network equipment 30；
Second network equipment 30 judges receive the test data packet when receiving the test data packet
Whether two interfaces are the last one interface in the test path；
When the second interface that second network equipment 30 receives the test data packet be not in the test path most
When the latter interface, second network equipment 30 according to the preset path information, work as by the determination in the multiple second interface
The second preceding output interface, and the test data packet is sent to by the first network equipment by second output interface
20, it is determined in the multiple first interface to repeat the first network equipment 20 according to the preset path information
The first current output interface, when receiving the test data packet, judges to receive the survey to second network equipment 30
The step of whether second interface for trying data packet is the last one interface in the test path, until second network is set
Standby 30 determine that the second interface for receiving the test data packet is the last one described interface.
It understandably, may include that data packet successively passes through the sequencing of each interface and corresponding in preset path information
Interface index.Such as, it is assumed that the forward-path of preset path information is identical as test path, as follows: first interface 1, second
Interface 1；Second interface 2, first interface 2；First interface 3, second interface 3, but assume second interface 3 be test path in most
The latter interface.Based on the sequence, it is the first current output interface that first network equipment 20, which can determine first interface 1 just,
Then first network equipment 20 is sent to second network equipment 30 by the first output interface, second interface 1.
Second network equipment 30 is when receiving test data packet, it can be determined that receive the test data packet second connects
Whether mouthful 1 be the last one interface in the test path.Because second interface 1 is not that the last one in test path connects
Mouthful, so, second network equipment 30 is based on preset path information, can determine that second interface 2 is that the second current output connects
Mouthful, and test data packet is sent to by the first network equipment 20 by the second output interface, first interface 2, then again by
First network equipment 20, second network equipment 30 repeat above-mentioned test data packet forwarding step.When second interface 3 receives survey
When trying data packet, second network equipment 30 may determine that the second interface for receiving test data packet is last in test path
One interface, at this point, can stop to 20 transmitted test data packet of first network equipment.
As an alternative embodiment, first network equipment 20 can be to packet encapsulation preset path information
When, based on the first interface for each jump that preset path information determines；Similarly, second network equipment 30 can be connects for the first time
When receiving the test data packet for being packaged with preset path information, based on the second interface for each jump that preset path information determines.
It, can first interface, second based on determined by first network equipment 20, second network equipment 30 in transmitted test data packet
Interfacing order carrys out mutual transmitted test data packet.Based on this, first network equipment 20, which may not need, is receiving test number every time
When according to packet, the first current output interface is just determined；Similarly, second network equipment 30, which may not need, is receiving test every time
When data packet, the second current output interface is just determined.
Before step S220, method may include: that the first network equipment 20 controls at the multiple first interface
In connection (UP) state；Second network equipment 30 controls the multiple second interface and is in connection (UP) state.
In the present embodiment, first network equipment 20 can control itself all first interface and be in connected state,
It can be control multiple first interfaces in need of test and be in connected state.Similarly, second network equipment 30 can be controlled
It makes itself all second interface and is in connected state, be also possible to control multiple second interfaces in need of test and be in connect
Logical state.The particular number of the first interface, second interface that need to control connection can be configured according to the actual situation, here
It is not especially limited.
In the present embodiment, before testing preset path information, it usually needs ensure more in first network equipment 20
A first interface can be normally connected to, and multiple second interfaces in second network equipment 30 can be normally connected to, to avoid because of
There is the interface that cannot be normally connected in one interface, second interface, and data packet can not be forwarded, to can not achieve pre-
If the problem of test of routing information.
Step S230 determines that the second interface for receiving the test data packet is the survey in second network equipment 30
When trying the last one interface in path, second network equipment 30 is based on the test data packet output data packet to test
Equipment 40 wraps the testing result for determining the preset path information for the test equipment 40 based on the data.
In the present embodiment, second network equipment 30 can export the result data packet after forwarding to test equipment 40, should
Result data packet may include the data packet that test equipment 40 is sent to first network equipment 20.Test equipment 40 can be by right
Result data packet is parsed, and the testing result of preset path information is obtained.Testing result can be expression preset path information
Normal first as a result, the second result to indicate preset path Information abnormity.Wherein, preset path information can normally manage
Solution is that the actual depth of forward-path in preset path information is identical as the depth that test obtains, and can pass through forward-path reality
The forwarding of existing test data packet, that is, forward-path are complete and correct.If forward-path is imperfect or incorrect, will
Obtain indicating the testing result of preset path Information abnormity.
For example, step S230 may include: when the data packet of second network equipment 30 output includes the survey
When the quantity of the examination data packet first interface passed through in repeating process and/or second interface, the test equipment 40 is according to institute
The quantity for stating first interface or second interface determines the depth of forward-path corresponding to the preset path information.
It may include: test data packet in the data packet that second network equipment 30 is exported to test equipment 40 in repeating process
The quantity of the quantity of the first interface of the middle process first interface that perhaps test data packet passes through in repeating process is surveyed
The quantity for the first interface that examination data packet is passed through in repeating process and the quantity of second interface.
Test equipment 40 can be according to the quantity for the first interface that test data packet is passed through, or according to the number of second interface
Amount, or according to the quantity of first interface and the quantity of second interface, determine the depth of forward-path.The depth of forward-path is just
The quantity of first interface or second interface.For example, if the quantity for the first interface that test data packet is passed through is 255, then in advance
If the depth of forward-path corresponding to routing information is 255.
When in the quantity and the preset path information for the first interface that the test data packet passes through in repeating process
First interface quantity it is not identical when, alternatively, the number for the second interface passed through in repeating process when the test data packet
When amount is not identical as the quantity of the second interface in the preset path information, alternatively, when the test data packet is forwarded over
The quantity of the first interface passed through in journey is not identical as the quantity of the first interface in the preset path information, and the test
The quantity of second interface in the quantity for the second interface that data packet is passed through in repeating process and the preset path information is not
When identical, it is abnormal to determine that the preset path information exists.
In the present embodiment, for test data packet in one first interface of every process, second network equipment 30 can be in number
According to the interface message for recording the first interface successfully passed through in packet；Or test data packet it is every by a second interface when,
First network equipment 20 records the interface message of the first interface successfully passed through in the packet；Alternatively, test data packet is every
