... ... ...
In conventional manner, VTEP equipment 101 is receiving route messages, and ED equipment is parsed from route messages After 102 gateway address 10.1.1.1/24, due to gateway address 10.1.1.1/24 and the VTEP equipment 101 of ED equipment 102 Gateway address 10.1.1.1/24 is identical, and therefore, VTEP equipment 101 will not generate gateway address in local routing table 10.1.1.1/24 network segment routing, terminates the processing to the route messages.
Unlike traditional approach, in the embodiment of the present application, VTEP equipment 101 is receiving route messages, and from road After gateway address 10.1.1.1/24 by parsing ED equipment 102 in message, although the gateway address of ED equipment 102 10.1.1.1/24 identical as the gateway address 10.1.1.1/24 of VTEP equipment 101, but VTEP equipment 101 is still in local routing The network segment generated in table for gateway address 10.1.1.1/24 routes, and ginseng is shown in Table 1, for for the gateway address 10.1.1.1/24 the example of network segment routing, it is without limitation.
In one example, compatible in order to be carried out with traditional approach, then it can also be distributed network in the embodiment of the present application Configuration ARP detecting function is closed, and enables ARP detecting function or removes enabled ARP detecting function.If VTEP equipment 101 enables ARP Detecting function, then VTEP equipment 101 is handled using the scheme of the embodiment of the present application, if VTEP equipment 101 is not enabled on ARP spy Brake, then VTEP equipment 101 is handled using traditional approach.
Based on this, in the embodiment of the present application, VTEP equipment 101 is receiving route messages, and solves from the route messages After the gateway address 10.1.1.1/24 of ED equipment 102 is precipitated, if the gateway address 10.1.1.1/24 and VTEP of ED equipment 102 is set Standby 101 gateway address 10.1.1.1/24 is identical, then VTEP equipment 101 can also judge the whether enabled ARP of VTEP equipment 101 Detecting function.If it is, VTEP equipment 101 can generate in local routing table is directed to gateway address 10.1.1.1/24 Network segment routing, ginseng is shown in Table 1.If it is not, then VTEP equipment 101 can forbid generating in local routing table for the net The network segment routing for closing address 10.1.1.1/24 does not generate the network segment routing for gateway address 10.1.1.1/24.
In the above-described embodiments, it describes VTEP equipment 101 and generates network segment routing, VTEP equipment similar with aforesaid way 101 can also send route messages to ED equipment 102, and ED equipment 103 can also send route messages to ED equipment 102, finally, ED equipment 102 can generate network segment routing in local routing table, and ginseng is shown in Table 2.Similarly, ED equipment 103 can be in local Network segment routing is generated in routing table, ginseng is shown in Table 3.VTEP equipment 104 can generate network segment routing, ginseng in local routing table It is shown in Table 4.

Step 202, host 105 sends datagram to VTEP equipment 101, subsequent to be known as data message 1.
Wherein, when host 105 needs to be implemented certain business, 1 can be sent datagram to host 106, and the data Message 1 is sent to VTEP equipment 101 by host 105.
Where it is assumed that host 106 is silent host, i.e., host 106 it is online after, do not send gratuitous ARP packet, that is, It says, VTEP equipment 101, ED equipment 102, ED equipment 103 and VTEP equipment 104, without learning the forwarding table to host 106 , data message 1 can not be sent to host 106.
Step 203, VTEP equipment 101 receives data message 1, wherein the purpose IP address of the data message 1 is host 106 IP address, it is assumed that purpose IP address 10.1.1.2/32.
Step 204, if local routing table is not present and the matched Host routes of purpose IP address 10.1.1.2/32 and deposits In the matched network segment routing of network segment belonged to purpose IP address 10112/32, then VTEP equipment 101 generates ARP request message, And ARP request message is sent according to the outgoing interface of network segment routing instruction, which may include purpose IP address 10.1.1.2/32, i.e., the purpose IP address of the ARP request message is 10.1.1.2/32, for the other of the ARP request message Content, details are not described herein.
Specifically, VTEP equipment 101 after receiving data message 1, judges to whether there is and the mesh in local routing table The matched Host routes of IP address 10.1.1.2/32 (routing of i.e. 32 IP address), if it is present directly pass through the master Machine routing sends datagram 1, repeats no more to this process.
If it does not exist, then VTEP equipment 101 judges whether this equipment is corresponding point of purpose IP address 10.1.1.2/32 Cloth gateway repeats no more this processing mode if it is not, then can be handled using traditional process.Due to destination IP The net that the network segment 10.1.1.0/24 of location 10.1.1.2/32 ownership and the gateway address 10.1.1.1/24 of VTEP equipment 101 belong to Duan Xiangtong, therefore, VTEP equipment 101 can determine that this equipment is the corresponding distributed network gate of purpose IP address 10.1.1.2/32, Further execute subsequent processing.
When VTEP equipment 101 is distributed network gate, ARP request message is can be generated in VTEP equipment 101, the ARP request The source IP address of message be VTEP equipment 101 IP address, purpose IP address 10.1.1.2/32, and double layer network (i.e. with The matched double layer network of gateway address 10.1.1.1/24) interior broadcast ARP request message, that is to say, that VTEP equipment 101 is by ARP Request message broadcasts to each host in double layer network, since the IP address of each host in double layer network is not 10.1.1.2/32, therefore each host will not return to arp response message, i.e. VTEP equipment 101 will not receive arp response message.
Unlike traditional approach, in the embodiment of the present application, in addition to the broadcast ARP request message in double layer network, VTEP equipment 101 can also be handled as follows: VTEP equipment 101 judges to whether there is in local routing table and purpose IP address The matched network segment routing of the network segment 10.1.1.2/32 belonged to (routing of i.e. non-32 IP address, such as routing of 24 IP address, The routing etc. of 16 IP address).If it does not exist, then terminating process.If it does, being presence and purpose IP address 10.1.1.2/32 the matched network segment routing of the network segment belonged to, then VTEP equipment 101 can also be sent using network segment routing and is somebody's turn to do ARP request message.For example, with reference to local routing table shown in table 1, belong to due to existing with purpose IP address 10.1.1.2/32 Network segment (such as network segment 10.1.1.0/24) matched network segment routing, i.e., the network segment that destination network segment is 10.1.1.1/24 routes, because This, can send the ARP request message, with no restrictions to this transmission process by the tunnel VXLAN A1.
Step 205, ED equipment 102 is after receiving ARP request message (including purpose IP address 10.1.1.2/32), if There is the matched network segment of the network segment belonged to purpose IP address 10.1.1.2/32 in local routing table to route, then ED equipment 102 The ARP request message is sent according to the outgoing interface of network segment routing instruction.
Specifically, after ED equipment 102 receives ARP request message, judge to whether there is in local routing table and destination IP The matched Host routes of address 10.1.1.2/32, if it is present being handled using traditional process.If it does not exist, then ED equipment 102 judge whether this equipment is the corresponding distributed network gate of purpose IP address 10.1.1.2/32, if it is not, then using conventional flow Journey processing.Due to the network segment 10.1.1.0/24 of purpose IP address 10.1.1.2/32 ownership and the gateway address of ED equipment 102 10.1.1.1/24 the network segment belonged to is identical, and therefore, ED equipment 102 can determine that this equipment is purpose IP address 10.1.1.2/32 Corresponding distributed network gate.
Therefore, ED equipment 102 can also be handled as follows: ED equipment 102 judge in local routing table with the presence or absence of with The matched network segment routing of the network segment of purpose IP address 10.1.1.2/32 ownership.If it does not exist, then terminating process.If it does, There is the matched network segment of the network segment belonged to purpose IP address 10.1.1.2/32 to route, then ED equipment 102 can also be utilized and is somebody's turn to do Network segment routing sends the ARP request message.For example, with reference to local routing table shown in table 2, due to presence and purpose IP address 10.1.1.2/32 the matched network segment routing of the network segment belonged to, i.e., the network segment that destination network segment is 10.1.1.1/24 route, therefore, ED Equipment 102 can send the ARP request message by the tunnel VXLAN B1, with no restrictions to this transmission process.
Step 206, ED equipment 103 is after receiving ARP request message (including purpose IP address 10.1.1.2/32), if There is the matched network segment of the network segment belonged to purpose IP address 10.1.1.2/32 in local routing table to route, then ED equipment 103 The ARP request message is sent according to the outgoing interface of network segment routing instruction.
Wherein, the processing of ED equipment 103 is similar with the processing of ED equipment 102, and details are not described herein.
Step 207, VTEP equipment 104 is after receiving ARP request message (including purpose IP address 10.1.1.2/32), If the gateway of the network segment 10.1.1.0/24 that the purpose IP address 10.1.1.2/32 of ARP request message belongs to and VTEP equipment 104 The network segment of address 10.1.1.1/24 ownership is identical, then in double layer network (i.e. matched two layers with gateway address 10.1.1.1/24 Network) interior broadcast ARP request message.
Specifically, after VTEP equipment 104 receives ARP request message, judge that local routing table whether there is and destination IP The matched Host routes of address 10.1.1.2/32, if it is present being handled using traditional process.If it does not exist, then VTEP is set Standby 104 judge whether this equipment is the corresponding distributed network gate of purpose IP address 10.1.1.2/32, if it is not, then using tradition Flow processing.Due to the purpose IP address 10.1.1.2/32 network segment 10.1.1.0/24 belonged to and the gateway of VTEP equipment 104 The network segment of location 10.1.1.1/24 ownership is identical, and therefore, VTEP equipment 104 determines that this equipment is purpose IP address 10.1.1.2/32 Corresponding distributed network gate.
When VTEP equipment 104 is distributed network gate, VTEP equipment 104 can double layer network (i.e. and gateway address 10.1.1.1/24 matched double layer network) interior broadcast ARP request message, that is to say, that VTEP equipment 104 is by ARP request message Each host in double layer network is broadcast to, since the IP address of the host 106 in double layer network is 10.1.1.2/32, because This, host 106 can return to arp response message.
In addition to the broadcast ARP request message in double layer network, VTEP equipment 104 can also be handled as follows: judgement is originally Ground routing table whether there is to be routed with the matched network segment of purpose IP address 10.1.1.2/32.If it does not exist, then terminating process. If it is present can use network segment routing sends the ARP request message.
Step 208, VTEP equipment 104 is receiving host 106 for the arp reply message of ARP request message return Afterwards, the Host routes of host 106 are generated according to the arp reply message.
Specifically, VTEP equipment 104 is in double layer network after broadcast ARP request message, due to the IP address of host 106 10.1.1.2/32 identical as the purpose IP address 10.1.1.2/32 of the ARP request message, therefore, host 106 can return to ARP Response message.VTEP equipment 104 is after receiving the arp reply message, so that it may the Host routes for generating host 106, referring to Shown in table 5, for the local routing table example after study.In local routing table, the corresponding route table items of 10.1.1.2/32 are exactly For the Host routes of 10.1.1.2/32.
