Specific embodiment
For making the objects, technical solutions and advantages of the present invention become more apparent, develop simultaneously embodiment referring to the drawings, right
The present invention further describes.
The embodiment of the present invention still taking EVI network as a example.
In the traditional routing learning style of EVI network, ED realizes the MAC ground of control plane by virtual Gigabit EtherChannel
Location information announcement, therefore, every virtual Gigabit EtherChannel is in addition to undertaking the data message forwarding of corresponding VLAN in addition it is also necessary to undertake
The mac address information notice of corresponding VLAN, i.e. data traffic transmitting and control flow simultaneously in data channel；And, in order to
Realize the mac address information notice of corresponding VLAN in virtual Gigabit EtherChannel, ED also needs to all enable in every virtual Gigabit EtherChannel
Routing Protocol.Thus, with regard to producing following problem：
1) resource that, each ED issue mac address information is consumed and the quantity of the virtual Gigabit EtherChannel of this ED foundation are in
Linear relationship, and the increasing number with virtual Gigabit EtherChannel and linear increase.
For example, it is assumed that all there is same 10 VLAN in two adjacent website networkings, the ED of this two station networks it
Between will set up corresponding 10 virtual Gigabit EtherChannels, and the ED of wherein each station network needs in 10 virtual Gigabit EtherChannels
All enable Routing Protocol；If the VLAN quantity in this two station networks increases to 20 even more many, virtual Gigabit EtherChannels
Quantity also can accordingly increase to 20 even more many and be required to enable Routing Protocol.
2), when, each ED occurs VLAN change in this station network, not only need newly to set up correspondence for newly-increased VLAN
Virtual forwarding channel in addition it is also necessary to enable, in virtual forwarding channel, the mac address information that Routing Protocol issues newly-increased VLAN again
And carry out route learning.
For example, it is assumed that two adjacent station networks increased a new VLAN, the ED of this two station networks simultaneously
Between can be for the newly-increased newly-built virtual forwarding channel of VLAN, the mac address information due to newly-increased VLAN does not exist before this
Mutually issue between two station networks, thus for newly-increased VLAN, the ED of this two station networks needs by newly-built
Virtual forwarding channel enables the route learning that Routing Protocol carries out the issue of a mac address information and carries out this newly-increased VLAN.
3), when the data message flow forwarding in virtual Gigabit EtherChannel is excessive, multiplexing is issued in virtual Gigabit EtherChannel
Mac address information is easily lost.
But in embodiments of the present invention, the edge device of each station network can be realized each other using neighbor discovery process
The disposable batch of all mac address informations in station network is issued and to be realized the route learning of batch with this.Such one
Come, the neighbor discovery process when between each station network completes and thus completes when setting up of virtual Gigabit EtherChannel, control plane
The issue of mac address information and route learning also complete.Correspondingly, after the completion of neighbor discovery process, it is no need for leading to respectively
Cross the virtual Gigabit EtherChannel of each bar in foundation and enable Routing Protocol, and all MAC Address letters in difference distribution site network
Breath.Wherein, all mac address informations in station network as herein described, contain complete in all VLAN in station network
Portion's mac address information rather than refer in particular to all mac address informations in some VLAN.
Below, first the neighbor discovery process between station network is illustrated.
The ED of each station network, before noticing the mac address information of this station network, needs first and other website nets
The ED of network mutually finds and forms EVI neighborhood.Wherein, above-mentioned neighbor uni-cast can pass through EVI Neighbor Discovery Protocol
(EVI Neighbor Discovery Protocol, ENDP) is realizing.
Specifically, ENDP defines two kinds of entities, i.e. EVI neighbor uni-cast server (EVI Neighbor Discovery
Sever, ENDS) and EVI neighbor uni-cast client (EVI Neighbor Discovery Client, ENDC)；Wherein, ENDS
For safeguarding in same EVI network the END information of all ENDC and ENDS itself is also ENDC simultaneously.
Correspondingly, in an EVI network, the ED of an at least station network is configured to ENDS, remaining website net
The ED of network is then both configured to ENDC；And, the ED as ENDS only need to be enabled certainly as ENDS by configuring, and as ENDC
ED equipment then need the address by configuring specified ENDS.Wherein, the configuration to ED as herein described can be manual configuration,
Can also be automatically configuring of each ED realization by election.
When the new addition of station network has had the EVI network of ENDS, its ED is only used as ENDC and is noted by transmission
Volume request message and initiate registration request to specified ENDS, and carry the END information of itself in registration request message, should
The END information of ENDC includes the IP address of the ED as this ENDC and the station of the ED place station network as this ENDC
Point identification, sets up virtual Gigabit EtherChannel for other ED (ENDS and other ENDC) with it.
When ENDS receives the registration request of ENDC, the END information of this ENDC can be preserved and pass through registration reply message
Registration reply is carried out to this ENDC, wherein, because ENDS is also ENDC simultaneously, thus meeting in the registration reply message that sends of ENDS
Carry the END information of ENDS, the END information of this ENDS includes the IP address of the ED as this ENDS and conduct should
The site identity of the ED place station network of ENDS, sets up virtual Gigabit EtherChannel for other ED (ENDC) with it；
Meanwhile, if ENDS saves the END information of other ENDC before this also by the registration of other ENDC,
The END information of other ENDC also can be carried on registration reply message simultaneously and send to current initiation registration request by ENDS in the lump
ENDC.
Hereafter, initiate the ENDC of registration request after receiving ENDS and representing the registration reply succeeded in registration, foundation
The END letter of other ENDC that the END information of the ENDS that ENDS carries in registration reply message or be possible to carries simultaneously
Breath, this ENDC can be by interacting Intermediate System-to-Intermediate System (Intermediate with ENDS and other ENDC
System-to-Intermediate System, IS-IS) greeting (Hello) message of agreement realizes mutual neighbours and sends out
Show and set up virtual Gigabit EtherChannel to each other.Certainly, although it cannot be from ENDS for the ENDC first completing to register
Know the END information of the ENDC of post-registration, but the ENDC of post-registration accurately can find according to the END information that it obtains from ENDS
The ENDC that first registers and send first hello packet come to trigger the ENDC first registering and its neighbor uni-cast and set up virtual with
Too passage.
Neighbor discovery process described above understands, ENDC has the energy issuing self information to ENDS in registration request
Power and the ability accurately finding neighbours before virtual Gigabit EtherChannel is set up according to END information, ENDS has in registration reply
Oriented ENDC issues the ability of the information of self information and other ENDC.
Therefore, the embodiment of the present invention, by such ability, realizes mac address information once in neighbor discovery process
Property batch issue, specifically：
When ENDC initiates registration request to ENDS, the END information carrying this ENDC in registration request message is permissible
Include all mac address informations in this ENDC place station network simultaneously；
When the registration reply that ENDS succeeds in registration to ENDC feedback representation, carry ENDS's in registration reply message
END information can include all mac address informations in the station network of ENDS place simultaneously；Wherein, if now having other
In ENDS successful registration, then ENDS also can carry the END information of other ENDC in re-registration response message to ENDC, due to other this
The ENDC that a little ENDC report ENDS when initiating registration request necessarily also can include all MAC ground in its place station network
Location information, therefore, also includes other ENDC institutes in the END information of other ENDC that ENDS carries in registration reply message certainly
All mac address informations in station network；
When ENDC receives ENDS and represents the registration reply succeeded in registration, at least can obtain from the END information of ENDS
All mac address informations in the station network of ENDS place, if also carry in registration reply message to complete before this to register
Other ENDC END information, then ENDC can also obtain its of successful registration before it from the END information of other ENDC
All mac address informations in his ENDC place station network；
In addition, for first complete register ENDC for, its cannot from ENDS know post-registration ENDC END information
(including the mac address information of the ENDC place website of post-registration), therefore, when post-registration ENDC can according to its from
After the END information that ENDS obtains accurately finds the ENDC first registering, the ENDC of post-registration is except needing to send Hello report first
Outside literary composition is to trigger the ENDC first registering and its neighbor uni-cast and to set up virtual Gigabit EtherChannel, can also further virtual with
Send IS-IS Link State Protocol Data Unit (Link State PDUs, LSP) message too during the foundation of passage to lead to
Accuse all mac address informations in its place station network.
Refer to Fig. 2 it is assumed that having three ED, i.e. ED0～ED2, wherein, ED0 is ENDC for ENDS, ED1 and ED2, and
And, ED1 and ED2 and ED0 wishes to realize two layers of interconnection to each other：

S203, ED0 carry out registration reply to ED1 and carry the END information of ED0, wherein, ED0 in registration reply message
END information in addition to including the site identity of the IP address of ED0 and place station network, also include ED0 place website
Currently all mac address informations in network, issued to the mac address information batch of ED1 with realizing ED0；But due to now only
There is this ENDC of ED1 to initiate to register to ED0, thus ED0 will not issue the END information of other ED to ED1；
S204, ED1, when receiving registration reply message (expression is succeeded in registration) of ED0, can obtain ED0 place website
All mac address informations in network are simultaneously preserved；
S205, ED1 interact hello packet, to set up virtual Gigabit EtherChannel according to the END information of ED0 with ED0；
According in the station network of other side place after the completion of S206, ED0 and ED1 virtual Gigabit EtherChannel foundation among each other
All mac address informations set up corresponding MAC Address and forward item；
S207, ED2 initiate to register and carry in registration request message the END information of ED2 in the rear of ED1 to ED0, its
In, in the END information of ED2 in addition to including the IP address of ED2 and the site identity of place station network, also include ED2 institute
All mac address informations in station network, issued to the mac address information batch of ED0 with realizing ED2；
S208, ED0, when receiving the registration request message of ED2, can obtain all in the station network of ED2 place
Mac address information is simultaneously preserved；
S209, ED0 carry out registration reply to ED2 and carry the END information of ED0, wherein, ED0 in registration reply message
END information in addition to including the site identity of the IP address of ED0 and place station network, also include ED0 place website net
Currently all mac address informations in network, issued to the mac address information batch of ED1 with realizing ED0；And, due to now
There is the ED1 as ENDC to complete registration in ED2 in ED0, thus ED0 also can issue the END information of ED1, wherein, ED1 to ED2
END information identical with S201；
S210, ED2 when receiving registration reply message (expression is succeeded in registration) of ED0, can obtain simultaneously ED0 and
All mac address informations in the station network of ED1 place are simultaneously preserved；
S211, ED2 interact hello packet, to set up virtual Gigabit EtherChannel according to the END information of ED0 with ED0；
According in the station network of other side place after the completion of S212, ED0 and ED2 virtual Gigabit EtherChannel foundation among each other
All mac address informations set up corresponding MAC Address and forward item；
S213, ED2 also according to ED1 END information interact hello packet with ED1, to set up virtual Gigabit EtherChannel, and,
During setting up virtual Gigabit EtherChannel, ED2 also sends the LSP message of the END information carrying ED2 to ED1, with to ED1
Issue all mac address informations in the station network of ED2 place；
According in the station network of other side place after the completion of S214, ED1 and ED2 virtual Gigabit EtherChannel foundation among each other
All mac address informations set up corresponding MAC Address and forward item.
As above visible, the ENDC (ED2) initiating afterwards to register can obtain ENDS (ED0) by the registration reply of ENDS (ED0)
And all mac address informations in other ENDC (ED1) the place station network registered before it；The ENDC first registering
(ED1) can by the registration reply of ENDS (ED0) obtain all mac address informations in the station network of ENDS (ED0) place and
The process of setting up of the virtual Gigabit EtherChannel initiated by the ENDC (ED2) of post-registration obtains the ENDC (ED2) registering after which
All mac address informations in the station network of place；And ENDS (ED0) then can obtain initiating note to it by registration request process
All mac address informations in all ENDC (ED1 and ED2) the place station network of volume.
Thus, issued by the asynchronous batch of above-mentioned mac address information in neighbor discovery process, in EVI network
Each ED can complete the MAC obtaining virtual Gigabit EtherChannel opposite end ED place station network when setting up of virtual Gigabit EtherChannel
Address information simultaneously completes corresponding route learning, thus, it is no need for after virtual Gigabit EtherChannel completes to set up in order to local terminal exists
The mac address information of control plane is issued the route learning with opposite end ED and is enabled Routing Protocol in virtual Gigabit EtherChannel.
It should be noted that：
The embodiment of the present invention using all mac address informations in the place station network that ED issues as END information expansion
Exhibition, is so intended merely to reduce change to ENDP old process, but in actual applications it is also possible to by the institute in station network
There is mac address information to give batch as the information type outside a kind of information independent of END to issue；
The embodiment of the present invention END information issued to ENDS from ENDC is carried in registration request message and will be by
ENDS is carried in registration reply message to the END information that ENDC issues, and is so intended merely to reduce to ENDP old process
Change, but in actual applications, it would however also be possible to employ independent of other messages outside registration request message and registration reply message
To carry the mac address information that batch is issued；
And, the END information issued between ENDC is carried in LSP message the embodiment of the present invention, is simply so
Using the characteristic of LSP message portability mac address information, but in actual applications, used due to LSP message has transmission opportunity
