It is RB equipment 1,2 He of RB equipment to connect the primary RB equipment that the dummy node corresponding to the LAG1 of CE equipment 1 selects shown in figure
RB equipment 3 is spare RB equipment, and all there are neighborhoods with dummy node for RB equipment 1, RB equipment 2 and RB equipment 3.
In the embodiment of the present invention, the same TRILL distribution trees, and the first RB is all added in all RB equipment in TRILL network
Equipment is primary RB equipment, and therefore, each 2nd RB equipment receives CE by the link in LAG at least one 2nd RB equipment
After the third data message that equipment is sent, unicast encapsulation is carried out to the third data message, to obtain the first data message, then
First data message is sent to the first RB equipment, to realize spare RB equipment utilizations TRILL mode of unicast by the number of CE equipment
Primary RB equipment is sent to according to message；Wherein, the alias and two comprising the alias of destination node, ingress in the first data message
The mark of layer virtual network, wherein the alias of destination node is the alias of the first RB equipment, and the alias of ingress is set as virtual
The alias of node；The mark of two-layer virtual network can be virtual LAN（Virtual Local Area Network,
VLAN）ID or fine granulation label（Fine Gained Label）；First RB equipment receives at least one 2nd RB equipment and sends
The first data message.Wherein, the above-mentioned TRILL distribution trees in TRILL network further include except the first RB equipment, at least one the
At least one 3rd RB equipment outside two RB equipment, the first RB equipment, at least one 2nd RB equipment and at least one 3rd RB
Equipment is all the node of above-mentioned TRILL distribution trees, can be as the root node or child node of above-mentioned TRILL distribution trees.
It should be noted that in practical application, the mark of two-layer virtual network can be included in the first data message, also may be used
With the mark not comprising two-layer virtual network；If the mark for the two-layer virtual network for including in the first data message, then first
RB equipment can not change the mark of the two-layer virtual network, can also change the mark of the two-layer virtual network according to configuration.
In the embodiment of the present invention, the data message that the first RB equipment or the 2nd RB equipment are sent to CE equipment includes two-layer virtual network
Mark, and the first RB equipment or the 2nd RB equipment do not change the mark of the two-layer virtual network for illustrate.If CE
In the data message that equipment is sent out, do not include two-layer virtual network mark, then receive data message the first RB equipment or
2nd RB equipment can increase the mark of corresponding two-layer virtual network according to local policy in data message.If datagram
Include the mark of two-layer virtual network in text, and the mark of the two-layer virtual network needs to change, then needs to two-layer virtual net
The mark of network is modified.Similarly, the data message for being received from TRILL network, it is also desirable to corresponding carry out inversely processing,
For example, the mark of two-layer virtual network is deleted, alternatively, carrying out the inversely processing of above-mentioned modification.
For example, as shown in figure 3, RB equipment 2 and RB equipment 3 need to carry out the third data message received from CE equipment 1
Unicast encapsulates, and the first data message obtained after then encapsulating unicast is sent to RB equipment 1.
Step 202, the first RB equipment obtains the second data message according to first data message.
Specifically, the first RB equipment carries out unicast solution to the first data message that at least one 2nd RB equipment is sent
Encapsulation, to obtain third data message, the third data message can be broadcast, unknown unicast, multicast（Broadcast、
Unknown Unicast, Multicast, BUM）Message.
The first RB equipment carries out TRILL multicast encapsulation to the third data message, to obtain the second data message,
Second data message is made of heading and third data message, wherein the heading include TRILL multicasts mark and
The mark of the root node of TRILL distribution trees in TRILL network；The TRILL multicasts mark is used to indicate second data message
For multicast message；Second data message is for being sent to TRILL network, TRILL points in TRILL network belonging to the first RB equipment
The root node of hair tree will receive second data message.
Step 203, the first RB equipment is by TRILL distribution trees, at least one 3rd RB into the TRILL network
Equipment sends second data message.
Specifically, as shown in figure 3, the first RB equipment is after obtaining the second data message, into TRILL network, TRILL divides
The root node of hair tree sends the second data message, so that the root node is at least one third under the TRILL distribution trees
RB equipment sends second data message.
Wherein, root node sends second data message at least one 3rd RB equipment under the TRILL distribution trees
May include：The root node of above-mentioned TRILL distribution trees is after obtaining the second data message, according to including in the second data message
Multicast identifies, and knows that the second data message is multicast message, therefore, root node forwards second data to the child node of root node
Message；Similar, child node, according to the multicast mark for including in the second data message, is known after receiving the second data message
Second data message is multicast message, then forwards second data message to the child node of child node, and so on so that
At least one 3rd RB equipment can receive the second data message under TRILL distribution trees.
It should be noted that due in the above-mentioned technical proposal of the embodiment of the present invention, the data message that CE equipment is sent out is complete
Portion is sent to TRILL network by the first RB equipment, and the 3rd RB equipment that data message is received in TRILL network is not in
The problem of rpf check fails.
It should be noted that if the alias for the ingress for including in the first data message is the alias of dummy node, indicate
First RB equipment need not send the to the local member device in the corresponding two-layer virtual network of mark of two-layer virtual network
Three data messages receive the third data message itself sent out to avoid local member device.
Optionally, the above method is further comprising the steps of：
The first RB equipment carries out horizontal segmentation inspection to the alias of the ingress；If the first RB equipment inspections
It is identical to go out the alias alias of dummy node corresponding with the LAG of the ingress, the first RB equipment is according to described two
The mark of layer virtual network, the local member device into the two-layer virtual network in addition to the CE send the third number
According to message.
Specifically, the first RB equipment and at least one 2nd RB equipment all with the local member device in two-layer virtual network
Connection, local member device can also include at least one other CE equipment, such as in Fig. 3 in addition to including above-mentioned CE equipment
CE equipment 2.
First RB equipment needs to be sent in local member device except above-mentioned CE is set the third data message of acquisition simultaneously
Standby other outer CE equipment, i.e. the first RB equipment replicates above-mentioned third data message, to obtain at least one third number
According to message；The first RB equipment carries out horizontal segmentation inspection to the alias of the ingress, if the first RB equipment inspections
It is identical to go out the alias alias of dummy node corresponding with the LAG of the ingress, then judge that third data message is on
It states CE equipment and is sent to the 2nd RB equipment, then the first RB equipment does not send the third datagram to the CE equipment
Text receives the third data message itself sent out to avoid the CE equipment, i.e., the described first RB equipment is according to institute
The mark for stating two-layer virtual network, it is each local in the local member device into the two-layer virtual network in addition to the CE
Member device all sends a third data message.
For example, as shown in figure 3, RB equipment 1 receive RB equipment 2 transmission the first data message after, to the first datagram
Text carries out unicast decapsulation and is then replicated to third data message with obtaining third data message, will replicate the obtained
Three data messages are sent to CE equipment 2, but RB equipment 1 cannot send third data message to CE equipment 1, to avoid to sending out
The CE equipment 1 of third data message sends third data message, leads to loop occur, i.e., CE equipment 1 receives what itself sent out again
Third data message.If the first RB equipment also with other CE equipment（Such as the CE equipment 2 in Fig. 3）It is connected, and the CE equipment is also led to
It crosses LAG more to return and be linked into multiple RB equipment, these RB equipment do not include the first RB equipment that CE equipment 2 corresponds to LAG, then the first RB
Equipment does not also send third data message to other CE equipment.
Referring to FIG. 5, the flow of the embodiment two of the cut-in method of its TRILL network provided by the embodiment of the present invention
Schematic diagram is concrete methods of realizing of the first RB equipment by the data message forwarding received from TRILL network to CE equipment, is such as schemed

Step 501, the first RB equipment receives what at least one 3rd RB equipment described in the TRILL network was sent
4th data message.
Step 502, the first RB equipment carries out TRILL multicast decapsulations to the 4th data message, to obtain the
Five data messages.
Specifically, since the 4th data message received from TRILL network is multicast message, the first RB equipment
TRILL multicast decapsulations are carried out to the 4th data message, to obtain the 5th data message.
Step 503, the first RB equipment detects the link state between the first RB equipment and the CE equipment, if
The first RB equipment detects that the link is normal, executes step 504, if the first RB equipment detects the link event
Barrier executes step 505.
Specifically, the first RB equipment detects the link state between the first RB equipment and the CE equipment, if first
RB equipment detects that the state of link is normal, thens follow the steps 504；If the first RB equipment detects that the state of link is different
Often, it indicates that link breaks down, thens follow the steps 505.
Step 504, the first RB equipment sends the 5th data message by CE equipment described in the chain road direction.
Specifically, the first RB equipment directly sends the 5th data message by the normal link of state to CE equipment.
Step 505, the described first primary RB equipment sends TRILL protocol message at least one 2nd RB equipment,
In order to which at least one 2nd RB equipment is according to preset selection algorithm, second is selected at least one 2nd RB equipment
Primary RB equipment, the second primary RB equipment carry out TRILL multicast decapsulations to the 4th data message, to obtain the 5th
Data message, and send the 5th data message to the CE equipment.
Specifically, in above-mentioned method shown in fig. 5, since TRILL identical with the first RB equipment is added in the 2nd RB equipment
Distribution tree, if the 2nd RB equipment also receives the 4th data message, the 4th data message of the 2nd RB equipment pair carries out TRILL
Multicast decapsulates, to obtain the 5th data message.
Due to the link failure between the first RB equipment and CE equipment, then the first RB equipment cannot send the to CE equipment
Five data messages；First RB equipment sends TRILL protocol message at least one 2nd RB equipment, in order to it is described at least
One the 2nd RB equipment selects the second primary RB equipment according to preset selection algorithm at least one 2nd RB equipment, choosing
The 4th data message that the second primary RB equipment interconnections gone out receive carries out TRILL multicast decapsulations, to obtain the 5th datagram
Then text sends the 5th data message to the CE equipment.
Referring to FIG. 6, its physical topology figure for the access failure of TRILL network in the embodiment of the present invention, as shown,
CE equipment 4 sends the 4th data message to RB equipment 5, and RB equipment 5 is counted using the TRILL distribution trees in TRILL network by the 4th
Be sent to RB 1~RB of equipment equipment 4 according to message, due between RB equipment 1 and CE equipment 1 link break down, RB equipment 1 to
RB equipment 2 and RB equipment 3 send TRILL protocol message, and RB equipment 2 and RB equipment 3 are selected RB and set according to preset selection algorithm
Standby 2 be the second primary RB equipment, therefore RB equipment 2 carries out TRILL multicast decapsulations to the 4th data message, to obtain the 5th number
According to message, then the 5th data message is sent to CE equipment 1.
Referring to FIG. 7, the logic of the embodiment three of the cut-in method of its TRILL network provided by the embodiment of the present invention
Topological diagram, as shown, when the first RB equipment failure as the first primary RB equipment, at least one 2nd RB equipment
Each 2nd RB equipment can select the second primary RB equipment according to preset selection algorithm, new to re-elect out one
Primary RB equipment, i.e., the second primary RB equipment.Wherein, each 2nd RB is set in the first RB equipment or at least one 2nd RB equipment
The standby mark and the system banner of itself that can correspond to LAG to other RB device broadcasts itself in advance（System ID）, in this way,
After the first RB equipment breaks down, at least one 2nd RB equipment receives TRILL protocol message, knows that the first RB equipment occurs
Failure, the then alias of the dummy node sent according to the first RB equipment, it is same to judge whether itself corresponds to the first RB equipment
A dummy node, if the corresponding same dummy node, the 2nd RB equipment is according to the system banner of itself and other the 2nd RB
The system banner of equipment selects a 2nd RB equipment as new primary RB equipment, for example, wherein system banner can be selected
Maximum 2nd RB equipment is as new primary RB equipment.
For example, RB equipment 2 is the second primary RB equipment in Fig. 7, it is responsible for the work of RB equipment 1 by RB equipment 2, is counted to the 4th
TRILL multicast decapsulations are carried out according to message, to obtain the 5th data message, then send the 5th data message to CE equipment 1, i.e.,
RB equipment 2 is equivalent to above-mentioned first RB equipment, executes and is operated accordingly in the above method.
If CE equipment accesses TRILL network by a first RB equipment and the 2nd RB equipment, as being primary
After first RB equipment of RB equipment breaks down, by the 2nd RB equipment as primary RB equipment, CE equipment will become singly to return access
TRILL network.
As shown in fig. 7, RB equipment 2 is after becoming primary RB equipment, to two layers of void belonging to TRILL network and RB equipment 1
Quasi- Web Publishing TRILL LSP messages indicate that RB equipment 2 is current to indicate the neighborhood of RB equipment 2 and dummy node
Primary RB equipment.
