application example 1

[0140] 1. First, the mutual access between PC2 and PC1 is explained:

[0141] Step 1. After VTEP2 receives the message from PC2 to access PC1, it searches for the route and resets the MAC address of the message: the source MAC is set to MAC2 (the MAC address of the VXLAN interface of VTEP2), and the destination MAC address is set to MAC1 (VTEP1 the MAC address of the VXLAN interface);

[0142] Step 2. After setting the MAC address, perform VXLAN encapsulation and send it to VTEP1;

[0143] Among them, the content of the message format (excluding Data) is shown in Table 4:

[0144]

[0145] Table 4

[0146] Step 3. After VTEP1 receives the VXLAN message sent by VTEP2, it removes the outer MAC header, outer IP header and UDP header, and matches the entries in the forwarding table in VTEP1 according to the VNI and PC1 IP in the message, and matches to Table 3 The first item in the list (as shown in Table 5)

application example 2

[0184] 1. First, the mutual access between PC2 and PC1 is explained:

[0185] This access process is exactly the same as the mutual access between PC2 and PC1 shown in Application Example 1, and will not be repeated here.

[0186] 2. Explain the mutual access between PC2 and PC3:

[0187] Step 1. After VTEP2 receives the message from PC2 to access PC3, it searches for a route and resets the MAC address of the message: the source MAC is set to MAC2 (the MAC address of the VXALN interface of VTEP2), and the destination MAC address is set to MAC1 ( MAC address of the VXALN interface of VTEP1);

[0188] Step 2: After setting the MAC address, perform VXALN encapsulation and send it to VTEP1; the packet format is shown in Table 15:

[0192] Step 3. After VTEP1 receives the VXLAN message sent by VTEP2, it removes the outer MAC header, IP header and UDP header, and matches the entry in the forwarding table in VTEP1 according to the VNI and ...

Abstract

A message sending method, device, storage medium and terminal in a VXLAN axis networking mode, the method includes: receiving a message, querying an established forwarding table; the forwarding table includes one or more entries, and the The table item content includes virtual network identification VNI, destination IP address information, and next-hop parameter information, and the next-hop parameter information includes: next-hop message outer layer source IP address and User Datagram Protocol UDP port number; When the VNI carried in the message and the inner layer destination IP address match the VNI and the destination IP address information recorded in an entry in the forwarding table, the message will be forwarded according to the next hop parameter information recorded in the table entry to retweet. This application can realize the transmission of messages between terminals located in different network segments in the hub-spoke networking scenario.

Description

technical field [0001] This paper relates to the VXLAN message sending technology of virtual extensible local area network, especially a message sending method, device, storage medium and terminal under the VXLAN axis networking mode. Background technique [0002] Virtual eXtensible LAN (VXLAN) is a technology that uses the encapsulation form of "MAC in UDP" to encapsulate Layer 2 packets into a Layer 3 network, which provides a Layer 2 interconnection for scattered users. method and can provide business isolation for different tenants. With the rapid development of virtualization technology, VXLAN technology has been widely used. The VXLAN Tunnel End Point (VTEP) serves as the termination point of the VXLAN tunnel and is used to perform VXLAN encapsulation and decapsulation operations on data. [0003] However, for the networking architecture of the hub-spoke mode, the existing technology cannot realize the intercommunication between terminals on different network segment...
