When switching LAV, it can be interacted with purpose ED and distal end ED, realize the switching of LAV, specifically, as shown in figure 5, the present embodiment LAV
Switching method may include following steps：
Step 301, source ED judges whether to need LAV switching to purpose ED, when judging result is to be, executes step
302, otherwise terminate flow.
Preferably, source ED can judge whether to need LAV switching to purpose ED according to following strategy：
（1）When source ED is detected in LAV without active two layers of port of downlink, ED judgements in source need LAV switching to purpose
ED；Or
（2）Source ED determines LAV re-optimization, and when being assigned to purpose ED, and judgement needs LAV being switched to purpose ED.
In practical application, the priority of LAV is provided in EVI systems, on ED so that ED can judge certainly according to priority
Whether body as the specified of LAV turns originator, by taking system structure shown in Fig. 2 as an example, if ED1 is height for the priority of LAV1,
Priority for LAV2 is low, and ED2 is low for the priority of LAV1, and the priority for LAV2 is height, then ED1 is LAV1
It is specified turn originator, ED2 is that the specified of LAV2 turns originator, and certain priority can also be indicated by concrete numerical value, herein no longer
It repeats.

（Transfer Request, migration request）Field is the migration flag of 1bit；TA（Transfer Accept, migration are true
Recognize）For the migration acknowledgement bit of 1bit；F（First）For the start of message (SOM) packet labeling position of 1bit；L（Last）For the message of 1bit
End message marker bit.The detailed flag bit of Transfer VLAN id fields is as shown in figure 11, and wherein Reserved is 0-3
Reserved bit, remaining 12bit are VLAN-ID.
The TLV that the type is 254, is the new TLV extended on the basis of existing hello packet, relevant for carrying
The information such as mac list items, so that source ED and purpose ED, i.e. can complete moving for LAV between ED1 and ED2 by hello packet
Move past journey.
In the present embodiment, ED1 can carry Local MAC address entries and the first ageing time in the hello packet of transmission,
Specifically, ED1 can be by the positions TR 1 of TLV in hello packet, mark migration request, the positions TA 0, when not being related to hello fragments,
F sets 1 with L, fills Sequence Number identification message sequences（Initial value is 1）, filling own system ID is
Transfer Neighbor ID, mark initiate the system identifier of migration request, fill Transfer Timer values, give tacit consent to 30s（I.e.
First ageing time）, Transfer VLAN ID values are filled, the LAV ID of migration are identified, fill Transfer MAC, mark is moved
Move the Local MAC address entries of LAV1.
In this step, if the Local MAC table item sizes of LAV1 are more than a hello packet be carried by it is big
It is small, fragment processing can be carried out with L by the positions F in Flags fields at this time, specifically, can be by the positions F in first message
1, L position 0, by the positions F 0 in intermediate fragment, the positions L 0, Sequence Number are filled with preceding 1 slicing sequence+1, last position point

End equipment MAC address entries still can be used for forwarding after carrying out specific identifier, and be deleted after local timer reaches ageing time, protect
Card remains to carry out forwarded upstream to the flow that does not immediately switch in transit time, but for Local MAC address entries, then must be to
ED3 notices are deleted, so that downlink traffic is changed to be forwarded to ED2 by ED3 by being forwarded to ED1.
Step 602, ED2 receives ED1 and sends hello packet, handles hello packet.
After ED2 receives hello packet, you can whether determination needs the LAV migrated effective in local, only exists in LAV
When locally significant, hello packet can just be handled, to the hello packet of ED1 returning responses.
Step 603, ED2 returns to hello packet to ED1.
Specifically, after ED2 receives the migration request of ED1, determine migrated LAV after locally significant, you can to this
Hello packet is handled, and is responded, and the hello packet for carrying TYPE254 classes TLV defined in the present invention is returned, wherein：
TR set 0, response message not set；
The positions TA 1, mark receive migration request；
Sequence Number：Mark confirms request message, adds 1 to the sequence number of request message；
Transfer Neighbor ID：Fill migration person（That is ED1）System identifier, it is consistent with request message；
Transfer Timer：Receive neighbours（That is ED1）Value after with value be locally configured be compared, take both ends minimum value
Filling, while the ends ED2 start Helper Timer timers.
ED1 starts Transfer Timer timers after receiving the response message, according to last negotiation value.
Wherein, the time value in Transfer Timer is exactly the minimum of pre-set ageing time in ED1 and ED2
Value, in this way, ED1 and ED2 will according in the response hello packet Transfer Timer carry time as aging when
Between, and start corresponding timer.
Step 604, ED1 receives the hello packet that ED2 is returned.
ED1 can according to the time that the Transfer Timer in the TLV in the hello packet are carried as ageing time,
And start corresponding timer
