Include: determining the corresponding outgoing interface of network packet in above-mentioned target by searching for routing table, and further determine that the outgoing interface whether be
VLXAN interface.It is specifically based on the repeating process of three layers of forwarding of routing table, refers to the forwarding explanation of existing three layers of VXLAN, this
In repeat no more.
In the present specification, further, it in preset VXLAN forwarding conversational list, saves and above-mentioned target Intranet report
The corresponding forwarding session entry of text；
Wherein, above-mentioned forwarding session entry includes at least the corresponding inbound port of network packet in above-mentioned target, in above-mentioned target
It is the corresponding outer envelope message IP five-tuple information of network packet in the corresponding IP five-tuple information of network packet, above-mentioned target, above-mentioned
The exit port of the corresponding VNI of outer envelope message, above-mentioned outer envelope message.
For example, above-mentioned VXLAN forwards conversational list, example shown in Figure 2:
Table 2
In above-mentioned target the corresponding forwarding session entry of network packet correspond to occurrence can be as shown in table 2.
It should be noted that after above-mentioned network equipment creation preset VXLAN forwarding conversational list as shown in Table 2, when
It is subsequent with above-mentioned target in network packet be same flow subsequent packet be re-introduced into the above-mentioned network equipment after, then the subsequent report
Text can be by forwarding matching forwarding-table item corresponding with network packet in above-mentioned target in conversational list in VXLAN, directly by upper
It states chip and carries out VXLAN encapsulation, to realize fast packing and fast-forwarding process.
In the present specification, after determining whether network packet needs to be implemented VXLAN encapsulation in above-mentioned target, if above-mentioned mesh
Network packet needs to be implemented VXLAN encapsulation in marking, then above-mentioned package identification is inserted into network packet in above-mentioned target, by above-mentioned CPU
Network packet in above-mentioned target is sent to above-mentioned forwarding chip；
Wherein, which is used to indicate network packet in above-mentioned target and needs to be implemented VXLAN encapsulation.
For example, the CPU of the above-mentioned network equipment heading of network packet or message can be carried in above-mentioned target when realizing
Preset package identification is inserted into lotus designated position；The specific location and content of the package identification, length etc. in the present specification, no
Do concrete restriction.
It in the present specification, will be in above-mentioned target by above-mentioned CPU after being inserted into package identification in network packet in above-mentioned target
Network packet is sent to above-mentioned forwarding chip.
In the present specification, it is received in above-mentioned target after network packet in above-mentioned forwarding chip, to network packet in above-mentioned target
It executes after VXLAN is encapsulated and forwards.
