After configuration on having introduced VTEP31 and VTEP33, below from forbid broadcast forwarding label setting, ARP request
The message forwarding method of the application proposition is discussed in detail in terms of the forwarding two of message.
1) forbid broadcast forwarding label setting
Step 301：VTEP33 can obtain the status information of the DR mouths on VTEP31.
It should be noted that VTEP33 obtains the DR mouth status informations on VTEP31, can be one DR mouthfuls of DR mouth shapes
State information can also be multiple DR mouthfuls of DR mouths status informations, here without specifically defined.
Here it is illustrated so that VTEP33 obtains the status information of the DR mouths 1 on VTEP31 as an example.Certainly, in practical application
In, there is also other DR mouthfuls on VTEP31 and VTEP33, for example, there are there are DR mouths 4, DR on DR mouths 3, VTEP33 on VTEP31
3 and DR of mouth mouths 4 belong to DR groups 2, then VTEP33 obtains the status information of DR mouths 3, forbid broadcasting to the AC mouths setting under DR mouths 4
The method of forwarding is also similar with the method by taking DR mouths 1 as an example, and which is not described herein again.
Mode one：VTEP31 can be notified by the status information of DR mouths 1 by forwarding-table item synchronization message to VTEP33.
Specifically, VTEP31 can periodically check physical port port_11, port_12, port_13 of the binding of DR mouths 1
Whether normal, any physical port of port_11, port_12, port_13 is in UP states, and DR mouths 1 are at UP states.
In general, VTEP31 inhibits the forwarding tables such as list item in MAC address entries, the ARP of study to the subscriber's main station VM messages sent
Xiang Hou, VTEP31 can send forwarding-table item synchronization message to VTEP33, to synchronize the forwarding-table item that VTEP31 learns.At this point,
DR groups belonging to the state of DR mouths 1, DR mouths 1 can be identified (DR groups 1) and carried in the forwarding-table item synchronization message by VTEP31, so
The forwarding-table item synchronization message is sent to VTEP33 by the tunnels IPL VXLAN afterwards.
VTEP33 can obtain the DR mouths of forwarding-table item synchronization message carrying after receiving the forwarding-table item synchronization message
DR groups mark (i.e. DR groups 1) belonging to 1 state and DR mouth 1.
Mode two：VTEP31 and VTEP33 can periodically notice mutually the DR mouth states of itself.
Specifically, VTEP31 can periodically check physical port port_11, port_12, port_13 of the binding of DR mouths 1
Whether normal, any physical port of port_11, port_12, port_13 is in UP states, and DR mouths 1 are at UP states.
Then, VTEP31 can send the DR mouth state advertisement messages for DR mouths 1 to VTEP33.The DR mouthfuls of state advertisement disappears
Carried in breath DR mouths 1 state and DR mouths 1 belonging to DR groups mark (i.e. DR groups 1).
VTEP33 can obtain the DR mouths of the DR mouthfuls of state advertisement message carrying after receiving the DR mouthfuls of state advertisement message
DR groups mark (i.e. DR groups 1) belonging to 1 state and DR mouth 1.
Similarly, VTEP33 also can periodically send the DR mouth state advertisement messages for DR mouths 2 to VTEP31.
Step 302：VTEP33 can be searched and the DR mouths 1 in the state according to DR mouths 1 after determining that DR mouths 1 are in UP states
Corresponding DR mouthfuls of local, and all AC lockjaws configured on the local DR mouths found are set and only broadcast forwarding.
Specifically, VTEP33 can identify the correspondence with DR mouthfuls according to preset DR groups, search the above-mentioned DR got
1 corresponding DR mouthfuls of local (i.e. DR mouths 2) of group.
Then, VTEP33 can be that all AC mouthfuls (the i.e. AC mouths 2 and AC mouths 4) addition configured on DR mouths 2 forbids broadcast to forward
Label.
It should be noted that when VTEP33 gets multiple opposite end DR mouthfuls of states, and determine multiple opposite end DR mouthfuls and locate
In UP states, VTEP33 can search with multiple opposite end DR mouthfuls local DR mouthfuls be respectively associated, and be multiple locals for finding
All AC mouthfuls configured on each DR mouths in DR mouthfuls, which add, forbids broadcast forwarding label.
For example, there are there are DR mouths 4, DR mouths 3 and DR mouths 4 to belong to DR groups 2 (in Fig. 3 on DR mouths 3, VTEP33 on VTEP31
It is not shown).VTEP31 is also required to forbid broadcast forwarding label for all AC mouthfuls of additions configured on DR mouths 3.
2) forwarding of ARP request message
VM31 sends ARP request message by AGG1 to above-mentioned DR systems.Assuming that the VLAN that the ARP request message carries
TAG is tag 10.
During transmission, VM31 can be in the link that local is connected with VTEP31 and VTEP32, one link of Hash
Carry out the forwarding of ARP request message.It is assumed that link of the link that goes out of Hash between local and VTEP31, VM31 pass through the Kazakhstan
ARP request message is sent to VTEP31 by the link wished out.
Step 401:VTEP31 is after receiving the ARP request message, it may be determined that the VSI belonging to the ARP request message.
Specifically, it is assumed that VTEP31 receives the ARP request message of VM31 transmissions by physical port port_11.
VTEP31 can determine the physics inbound port port_ of the ARP request message according to preset DR mouthfuls and the binding relationship of physical port
DR mouths (i.e. DR mouths 1) bound in 11.
Then, VTEP31 can be configured on DR mouths 1 in AC mouths 1 and AC mouths 2, be searched and ARP request message carrying
It is AC mouthfuls corresponding (i.e. AC mouths 1) that VLAN identifies (i.e. tag 10).Then, VTEP31 can determine the AC mouthfuls based on the configuration of AC mouths 1
1 associated VSI, i.e. VSI vpnb.
Step 402：VTEP31 can in the ARP of local record inhibits list item, the VSIvpnb that search and determine and this
The matched ARP of IP address of ARP request message request inhibits list item.
ARP inhibits list item can be as shown in table 1：
| The IP address of request | MAC Address | VSI | AC mouthfuls |
Table 1
Step 403：If the IP address of the VSI vpnb and the ARP request message request that find and determine are matched
ARP inhibits list item, VTEP31 the MAC Address in list item can be inhibited to return to VM31 the ARP.
Step 404：If the IP address of the VSI vpnb and the ARP request message request that do not find and determine are matched
ARP inhibits list item, VTEP31 that can broadcast the ARP request message.
In broadcast, VTEP31 by the tunnel faces VXLAN that are recorded in broadcast lists, the tunnel faces IPL VXLAN, except should
Other AC mouthfuls except ARP request message is AC mouthfuls corresponding forwards the ARP request message.Wherein, which is above-mentioned true
The associated broadcast lists of VSI made.
Wherein, the corresponding AC of the ARP request message is to be configured on the DR mouths (i.e. DR mouths 1) for be received as the ARP request message
And with the VLAN of the ARP request message mark (VLAN 10) it is AC mouthfuls corresponding (i.e. AC mouths 1).
For example, in the present example it is assumed that the associated broadcast lists of VSI vpnb are denoted as broadcast lists 1, recorded in broadcast lists 1
Port have the AC mouths 1 configured on the tunnel faces VXLAN, the tunnel faces IPL VXLAN and DR mouths 1 of VTEP31 connections VTEP32
With AC mouths 3.
1) VTEP31 does not forward ARP request message, VTEP31 to pass through by AC mouths 1 (ARP request message is AC mouthfuls corresponding)
The AC mouths 3 configured on DR mouths 1 forward the ARP request message.
It should be noted that above-mentioned other AC mouthfuls further includes the AC mouths configured on other DR mouths on VTEP31, and singly hang over
AC mouths of VM connections on VTEP31 etc..
For example, there are there are DR mouths 4, DR mouths 3 and DR mouths 4 to belong to DR groups 2 (in Fig. 3 on DR mouths 3, VTEP33 on VTEP31
It is not shown).VTEP31 is also required to all AC mouthfuls configured on DR mouths 3 and forwards the ARP request message.
For another example, VM32 is mono- hangs on VTEP31, on the upper interfaces being connect with VM32 of VTEP31 configured with AC mouths 5 (in Fig. 3
It is not shown), then VTEP31 forwards the ARP request message by AC mouths 5.
2) the ARP request message is transmitted to VTEP32 by VTEP31 by the tunnel faces VXLAN.
Specifically, which can be carried out VXLAN encapsulation by VTEP31, VXLAN messages be generated, in this example, due to this
The corresponding VSI of ARP messages is VSI vpnb, and VSI vpn are corresponding with VXLAN 100, so the VXLAN of the VXLAN messages
It is identified as VXLAN100.
Then, the VXLAN messages for encapsulating ARP messages can be sent to VTEP32 by VTEP31 by the tunnel faces VXLAN.
3) the ARP request message is transmitted to VTEP33 by VTEP31 by the tunnel faces IPL VXLAN.
Specifically, which can be carried out VXLAN encapsulation by VTEP31, generate VXLAN messages.In this example, due to this
The corresponding VSI of ARP messages is VSI vpnb, and VSI vpn are corresponding with VXLAN 100, so the VXLAN of the VXLAN messages
It is identified as VXLAN100.
Then, the VXLAN messages for encapsulating ARP messages can be sent to by VTEP31 by the tunnel faces IPL VXLAN
VTEP33。
Step 405：VTEP33 is after receiving VXLAN messages, it may be determined that whether the VXLAN messages are in same DR systems
Opposite end VTEP (i.e. VTEP31) send.
Mode one：VTEP33, which can determine, receives whether the tunnel face of the VXLAN messages is the tunnel faces IPL VXLAN, if
It is that VTEP33 can determine that the VXLAN messages are what VTEP31 was sent.If it is not, then determining that the VXLAN messages are not VTEP31
It sends.
Mode two：VTEP33 can be based on the source IP address of the VXLAN messages, if the source IP address is the IP of VTEP31
Location, it is determined that the VXLAN messages are that VTEP31 is sent.If the source IP address is not the IP address of VTEP31, it is determined that should
VXLAN messages are not that VTEP31 is sent.
Step 406：It is sent if the VXLAN messages are VTEP31, and the ether network packet after VXLAN messages decapsulation
It is ARP request message, VTEP33 can search whether to deposit inhibits list item with the matched ARP of the ARP request message.
When realizing, VTEP33 can search whether the VXLAN for having with the VXLAN messages in local ARP inhibits table
It identifies (i.e. VXLAN 100) corresponding VSI (i.e. VSI vpnb) and the requested IP address of ARP request message is matched
ARP inhibits list item.
In this example, since VTEP31 and VTEP33 belong to same DR systems, the forwarding that is configured on VTEP31 and VTEP33
List item is identical.Matched ARP is not found on VTEP31 and inhibits list item, so matched ARP is also not present on VTEP33
Inhibit list item.
Step 407：If there is no matched ARP to inhibit list item, which is broadcasted.
When realizing, VTEP33 can obtain the broadcast lists for broadcasting the ARP request message.
Specifically, the VXLAN marks (i.e. VXLAN100) of the VXLAN messages can be read in VTEP33, then by VXLAN 100
Corresponding broadcast lists are denoted as broadcast lists 2 here as the broadcast lists for broadcasting the ARP request message.
Then, VTEP33 can be by recording in addition to provided with the AC mouths for forbidding broadcast forwarding label in broadcast lists 2
Other AC mouthfuls forwarding the ARP request message.
For example, the port of the broadcast lists 2 record includes the tunnel faces VXLAN that VTEP33 is connected with VTEP32, IPL
The tunnel faces VXLAN, AC mouths 2, AC mouths 4 on DR mouths 2, and singly hang over the AC mouths of local VM for connecting and (do not show in Fig. 3
Go out).
Since AC mouths 2 and AC mouths 4 are added to forbid broadcast forwarding label, so VTEP33 does not pass through the AC mouths 2 and AC
Mouth 4 forwards the ARP request message.
VTEP33 can be recorded by broadcast lists 2 with for connecting the AC mouths for singly hanging over local VM.
It should be noted that in existing EVPN networkings, there are horizontal segmentations in the tunnels VXLAN, i.e., from a VXLAN tunnel
The message that road receives will not be forwarded by another tunnel VXLAN, so in this example, since VTEP33 is from IPL
The tunnels VXLAN receive the VXLAN messages for being packaged with ARP request message, so what VTEP33 will not be recorded into broadcast lists 2
The tunnel faces VXLAN that VTEP33 is connected with VTEP32 forward the ARP request message.It will not be to receiving the ARP request message
Source port, the i.e. tunnel faces IPL VXLAN forward the ARP request message.
In the embodiment of the present application, since VTEP33 is after determining that DR mouths 1 are in UP states, by 1 associated DR mouths 2 of DR mouths
All AC of upper configuration are disposed as that broadcast is forbidden to forward so that the ARP request report for coming from VM31 that VTEP31 will be received
Text is transmitted to VTEP33, and VTEP33 is when broadcasting the ARP request message, due to not being forwarded by AC mouths 2 so that
The ARP request message is not sent further on back VM31, so not will produce loop.
