Go out in the Multi Topology aware Port Capability TLV after extension excellent for carrying site apparatus
The sub-TLV form of first level attribute, this sub-TLV can be described as Site-priority sub-TLV(website-priority
Sub-TLV), being described as follows of the most each field:
The type of Type:TLV is PRIORITY-TLV(priority TLV), value can be 223；
The length of Length:TLV, can be 51 bytes；
PRIORITY: priority attribute value；
The bridge MAC Address of Bridge MAC: equipment, form is XXXX-XXXX-XXXX.
The embodiment of the present invention carries out home site equipment competition in website neighbor discovery process.
The definition of ID attribute based on above-mentioned site apparatus, and the extension to EVI-ISIS hello packet,
Neighbor discovery process in the embodiment of the present invention comprises the steps that
Each ENDC sends logon message (the EVI-ISIS hello report carrying own priority to ENDS
Literary composition, the extended mode of this EVI-ISIS hello packet is ditto described)；ENDS receives what ENDC sent
After carrying the logon message of priority, (EVI-ISIS hello reports to return registration reply message to ENDC
Literary composition, the extended mode of this EVI-ISIS hello packet is ditto described), this registration reply message carry same
The information of all ENDC in one EVI network example, including the ID of site apparatus, priority etc.
Information；After ENDC receives response message, set up with each ENDC in same EVI network example
EVI Link.By above flow process, each EVI site apparatus can obtain the priority of its neighbor site equipment,
So, each EVI site apparatus just can according to the priority of oneself and the priority of neighbor site equipment,
Campaign for out home site equipment, and by election or/and the priority of neighbor site equipment is saved in this locality.
As it was previously stated, the EVI site apparatus in same EVI network example, pass through neighbor discovery process
In local maintenance ENDP neighbor table, wherein have recorded the relevant information of the ENDP neighbours of this site apparatus.
The ENDP that the priority of election or neighbor site equipment can be recorded correspondence by the embodiment of the present invention is adjacent
Occupy in list item.Such as, the content of ENDP neighbor entry comprises the steps that the ID(device number of neighbor site equipment
+ network ID), the IP address of neighbor site equipment, EVI between this site apparatus and neighbor site equipment
The mark of Link, the priority etc. of neighbor site equipment；Or, the content of ENDP neighbor entry comprises the steps that
ID(device number+the network ID of neighbor site equipment), the IP address of neighbor site equipment, this site apparatus
And the mark of the EVI Link between neighbor site equipment, for representing that whether neighbours are the marks of home site equipment
Knowledge information.ENDP neighbor table will be used for Subsequent MAC addresses information announcement process.
By above-mentioned neighbor uni-cast flow process it can be seen that due to the EVI-ISIS mutual in neighbor discovery process
Carrying site apparatus precedence information in hello packet, the most each site apparatus can know same EVI
The priority of each site apparatus in network example, such that it is able to elect according to the priority of each site apparatus
Home site equipment.Further, EVI-ISIS hello packet also carries bridge mac address information, because of
This each site apparatus it can also be seen that the bridge MAC Address of each site apparatus in same EVI network example,
Thus when the priority of two site apparatus is equal, the bridge MAC Address of these two site apparatus comparable
Size, thus compete home site equipment.Such as, the site apparatus that bridge MAC Address is little is competed successfully.
After EVI Link between EVI site apparatus sets up, each site apparatus is initiated mac address information and is led to
Announcement process, the most each site apparatus execution flow process as shown in Figure 4:
Step 401, inquires about the ENDP neighbor table that this site apparatus is safeguarded.
Step 402, judges with the ENDP neighbor table of this site apparatus for foundation: if according to ENDP
Neighbor table judges that this site apparatus is non-master site apparatus, has home site equipment in its neighbor site equipment,
Then perform step 403；If judging that this site apparatus is home site equipment, then according to ENDP neighbor table
Perform step 404.
Step 403, the mac address information safeguarded by this site apparatus is carried on LSP message and is sent to this
Home site equipment, this flow process terminates.
Step 404, the mac address information safeguarded by this site apparatus is carried on LSP message and is sent to it
All of neighbor site equipment, this flow process terminates.
After home site equipment receives the LSP message that the transmission of non-master site apparatus comes, according to wherein carry
Mac address information safeguards the mac address table of this site apparatus, and safeguards LSDB(Link State
Data Base, LSD), this home site equipment is according to the ENDP neighbor table of this site apparatus
Judge that its neighbor site equipment is non-master site apparatus, therefore be transmitted to remove by the LSP message received
Other each neighbor site equipment beyond the sender of this LSP message.Non-master site apparatus receives home site
After equipment sends the LSP message come, the mac address information according to wherein carrying safeguards this site apparatus
Mac address table, and safeguard LSDB.
It is similar to, when EVI site apparatus learns to mac address information from local site network, this station
Point device inquires about the ENDP neighbours that this site apparatus is safeguarded, with the ENDP neighbor table of this site apparatus for depending on
According to judging: if judging that this site apparatus is non-master site apparatus according to ENDP neighbor table, it is adjacent
Occupy and site apparatus has home site equipment, then the mac address information that this site apparatus learns is carried on
LSP message is sent to this home site equipment；If judging that this site apparatus is main according to ENDP neighbor table
Site apparatus, then be carried on LSP message by the mac address information that this site apparatus learns and be sent to it
All of neighbor site equipment.After home site equipment receives the LSP message that the transmission of non-master site apparatus comes, root
Safeguard the mac address table of this site apparatus according to the mac address information wherein carried, and safeguard LSDB,
And the LSP message received is transmitted to other each neighbor station in addition to the sender of this LSP message
Point device.
It is similar to, when the LSP message of configuration sends time arrival on EVI site apparatus, also can trigger
Carried out the announcement process of mac address information by LSP message, this process is noticed with above-mentioned MAC Address
Process is similar to, and does not repeats them here.
Optionally, in above-mentioned mac address information announcement process, the ENDP neighbor table of institute's foundation also can be by it
Its record has home site equipment election or neighbor site priority facility (further to may also include neighbours
The bridge MAC Address of site apparatus) data structure replace.
In LSP message mutual in above-mentioned flow process in addition to carrying the mac address information needing to notice,
Also portability sends the ID attribute information of site apparatus of this LSP message.Fig. 5 shows a kind of EVI-ISIS
The form of LSP message.Wherein, being described as follows of each field:
Type(type): MAC-RI, value is 147；
Length(length): 5+6*N, N represent the quantity of local mac address；
Topology-Id/Nickname(topology ID/ is called): depend on actual application environment to identify transmission
Person.In EVI, this field is invalid, is arranged to 0, represents that MAC Address below can by source ED(i.e.
Edge device) arrive, need not distinguish mono-equipment of topological sum Nickname(may have multiple Nickname)；
Confidence(credibility): for the preferred of MAC Address of conflicting.If you are using, need
Increase related command row；
RESV: reserved bit, this field inserts the ID of the site apparatus of equipment, to ensure and current

Practical application request that should be the most stable in view of core net, in a preferred embodiment of the present invention
In, the priority that definable each EVI site apparatus is configured by manual mode is 0-15(or other numerical value
Interval, describes as a example by 0-15 at this), and be gradually lowered according to the order priority from 0 to 15.One
Denier elects home site equipment, and on home site equipment, the priority of all neighbor site equipment all can be arranged to
16, then in any case by the priority of manual mode amendment home site equipment, the priority of this home site
The most still will can exist as home site equipment less than 16, priority update will not be triggered, and then will not touch
Send out home site election process, restart unless there are site apparatus or new site equipment adds competition.Concrete, should
Home site equipment election contest process in preferred embodiment comprises the steps that
Each ENDC sends to ENDS and carries own priority and the logon message of bridge MAC Address
(EVI-ISIS hello packet).After ENDS receives the logon message that ENDC sends, according to this website
Equipment and the priority of distance station point device and bridge MAC Address compete home site equipment, if this website sets
For competing successfully, then the priority of this site apparatus He other ENDC is carried on registration reply message
(EVI-ISIS hello packet) returns to this ENDC；If this site apparatus is competed unsuccessfully, then abandon competing
Strive home site equipment, the priority of this site apparatus is set to 16, and by this site apparatus and other ENDC
Priority and bridge MAC Address be carried on registration reply message (EVI-ISIS hello packet) and return to this
ENDC, wherein the priority of this site apparatus is 16.
After ENDC receives the registration reply message (EVI-ISIS hello packet) that ENDS returns, root
Home site equipment is competed according to this site apparatus and the priority of each neighbor site equipment and bridge MAC Address, as
Really this site apparatus is competed unsuccessfully, then abandon competing home site equipment, the priority of this site apparatus be set to
16, and upper once to ENDS send logon message time, by priority (this priority of this site apparatus
Value is 16) it is carried on logon message and is sent to ENDS.
Realize process for the clearer explanation embodiment of the present invention, enter as a example by a concrete scene below
Row explanation.
As shown in Figure 6, EVI network exist 5 equipment, be designated as respectively equipment 1, equipment 2, equipment 3,
Equipment 4, equipment 5, these 5 equipment are respectively as EVI site apparatus, and they have same extension
VLAN, sets up fully-connected network each other.The span of website priority is [0,15], according to 0-15
Order, decreasing priority.On equipment 1-5, the attribute information of configuration is as shown in table 1:
The attribute of configuration on table 1, equipment 1-5
| Equipment | Network ID | Device numbering | Priority |
| Equipment 1 | 100 | 1 | 2 |
| Equipment 2 | 100 | 2 | 1 |
| Equipment 3 | 100 | 3 | 1 |
| Equipment 4 | 100 | 4 | 3 |
| Equipment 5 | 200 | 5 | 1 |
Specify according to ENDP agreement, between the EVI network of same Network ID, neighbours can be set up,
The EVI Link consulting to set up after EVI Link, ENDP consult can be as shown in Figure 7.Wherein, equipment 2
With the EVI Link between equipment 1 is designated as Elink0, the EVI Link between equipment 2 and equipment 3 is designated as
Elink1, the EVI Link between equipment 2 and equipment 4 is designated as Elink2, between equipment 1 and equipment 3
EVI Link is designated as Elink3, and the EVI Link between equipment 1 and equipment 4 is designated as Elink4, equipment 3
With the EVI Link between equipment 4 is designated as Elink5.
Equipment 2 launches the competition of home site equipment together with other neighbor device, is reported by EVI-ISIS hello
Literary composition interaction priority level, by priority ratio relatively, equipment 1, equipment 4 abandon home site equipment contention automatically,
And be 16 by the priority modification of oneself in upper once hello packet is mutual.Equipment 2 and equipment 3 excellent
First level is equal, it is therefore desirable to carry out bridge MAC Address comparison, by comparison, the bridge MAC ground of equipment 2
Location is less, and equipment 3 abandons home site equipment contention, by the priority of oneself in upper once hello packet
It is revised as 16.
Through above-mentioned hello packet interaction, the ENDP neighbor table on equipment 1 can be as shown in table 2,
ENDP neighbor table on equipment 2 can be as shown in table 3, and the ENDP neighbor table on equipment 3 can be such as table 4
Shown in, the ENDP neighbor table on equipment 4 can be as shown in table 5.
ENDP neighbor table on table 2, equipment 1
ENDP neighbor table on table 3, equipment 2
ENDP neighbor table on table 4, equipment 3
ENDP neighbor table on table 4, equipment 4
It should be noted that the IP address table in above-mentioned table 2, table 3, table 4 be shown as A.A.A.A, B.B.B.B,
C.C.C.C or D.D.D.D, is different only for representing the IP address of distinct device, and concrete numerical value needs
Determining according to network design, the representation of this IP address does not here have other implication.
After equipment receives LSP message, with ENDP neighbor table for according to judging: work as ENDP
Neighbor table there is priority be less than the list item of 16, then LSP message EVI Link in this list item is sent；
When ENDP neighbor table not having priority be less than the list item of 16, then get rid of the source port of this LSP message,
EVI Link from the list item that other priority is 16 sends.
According to above principle, when equipment 1 needs to notice mac address information, this mac address information
Announcement process be:
When equipment 1 has mac address information to need to notice, (such as study is to MAC Address or notice
The cycle of mac address information arrives), inquire about the ENDP neighbor table (as shown in table 2) that this equipment is safeguarded,
Find that in its neighbor device, the numerical priority value of equipment 2 is less than 16, it is thus determined that equipment 2 is home site equipment；
Equipment 1 constructs LSP message, wherein carry need to notice mac address information (as MAC1,
MAC2, MAC3), the reserved field of this message is filled in Site ID (wherein, the Network of this equipment
ID=100, device number=1), by the Elink0 between equipment 2, this LSP message is sent to equipment
2。
After equipment 2 receives this LSP message, safeguard the mac address table of this equipment according to this LSP message,
Inquire about the ENDP neighbor table (as shown in table 3) of this plant maintenance, find the priority number of its neighbor device
Value is 16, it is thus determined that these neighbor devices equal non-master site apparatus, this equipment is home site equipment；If
According to the Site ID of the message sender carried in this LSP message, standby 2 determine that the sender of this message is for setting
Standby 1, thus be excluded that the Elink0 of equipment 1 correspondence in ENDP neighbor table, by remaining numerical priority value be
EVI Link(Elink1, Elink2 that the neighbor device (equipment 3, equipment 4) of 16 is corresponding), by this LSP
Message is transmitted to equipment 3 and equipment 4.
After equipment 3 receives this LSP message, safeguard the mac address table of this equipment according to this LSP message,
Inquire about the ENDP neighbor table (as shown in table 4) of this plant maintenance, find equipment 2 in its neighbor device
Numerical priority value is less than 16, it is thus determined that equipment 2 is home site equipment, this equipment is non-master site apparatus；
But this LSP message will not be transmitted to the equipment 2 of the sender as this LSP message by equipment 3 again.In like manner,
Equipment 4 also will not forward the LSP message received.
In like manner, when equipment 3 or equipment 4 need to notice mac address information, its handling process and above-mentioned stream
Journey is similar to.
By above flow process it can be seen that when non-master site apparatus have mac address information need notice time,
It is sent to home site equipment, by home site by carrying the LSP message needing the mac address information passed through
This LSP is transmitted to other non-master site apparatus by equipment, non-master site apparatus after receiving LSP message not
This LSP message can be forwarded.
When equipment 2 needs to notice mac address information (such as study to MAC Address or notice MAC
The cycle of address information arrives), inquire about the ENDP neighbor table (as shown in table 3) that this equipment is safeguarded, send out

After, the mac address information of oneself this locality is again sent to this home site equipment.The machine of delaying of home site equipment,
Do not affect mac address information that miscellaneous equipment acquired and converting flow (relevant with home site itself
Except mac address information).
When new site apparatus adds the EVI network being complete the competition of home site equipment, it needs as adding
The EVI network entering to be not fully complete competition sends the priority of oneself like that to each site apparatus.Each non-main website
Point device responds priority 16 to this site apparatus, and home site equipment responds the preferential of oneself to this site apparatus
Level, if the site apparatus priority ratio current master station point device priority being newly added is low, it is non-just as other
The same message sending priority 16 to all neighbours of home site equipment；If its priority ratio home site
Equipment is high, oneself is home site equipment, issues the priority of oneself, current master station point device to all neighbours
Compete unsuccessfully, send the hello packet of priority 16 to the site apparatus that is newly added and oneself is received
LSP is transmitted to the site apparatus being newly added；After other non-master site apparatus receives new priority, by original master station
Point device priority puts 16, and sends LSP message to the site apparatus being newly added.
The embodiment of the present invention can effectively reduce the LSP message amount under EVI multi-site equipment complexity networking,
With according to the embodiment of the present invention, all site apparatus can obtain only one home site after election contest and set
Standby, the mac address information of oneself is synchronized to home site equipment by each site apparatus, home site equipment enter
