Problems solved by technology

[0004] However, in some scenarios, the network card of tenant server 1 does not support multiple VLANs. For example, the network card of tenant server 1 can only send packets carrying VLAN1, but not packets carrying VLAN2.
In this way, when tenant server 1 sends a management packet through the network card, it carries VLAN1. After receiving the manageme

example 2

[0158] Wherein, the edge node 113 determines the VPN instance 2 corresponding to the management message 2, which may include:

[0159] The edge node 113 determines the VPN instance associated with the incoming interface according to the incoming interface of the management packet 2, and determines the VPN instance corresponding to the incoming interface as the VPN instance corresponding to the management packet 2, that is, VPN instance 2.

[0160] For example, referring to the above embodiment, since the logical interface S2 of the edge node 113 corresponds to the logical interface S1 of the management gateway 121, when the management gateway 121 sends the management message 2 through the logical interface S1, the edge node 113 receives the management message 2 through the logical interface S2. The management message 2, that is, the edge node 113 determines that the incoming interface of the management message 2 is the logical interface S2. Since the VPN instance corresponding...

Abstract

The invention provides a message transmission method and device, and the method comprises the steps: receiving a first management message transmitted by a tenant server, and determining a first VPN instance corresponding to the first management message; querying a routing table corresponding to the first VPN instance through a destination IP address of a first management message to obtain a secondVPN instance; modifying a source IP address of the first management message into a management IP address of the tenant server to obtain a second management message, and querying a routing table corresponding to the second VPN instance through a destination IP address of the second management message to obtain a first output interface; and sending the second management message to a management server through the first output interface. Through the technical scheme of the invention, the management message can be correctly transmitted.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a message transmission method and device. Background technique [0002] In the Overlay network (that is, the virtual network), the tenant's server (subsequently referred to as the tenant server) can send business packets and management packets, and each type of packet corresponds to a VPN (Virtual Private Network, virtual private network) instance . For example, tenant server 1 is connected to edge node 1, and VPN instance 1 and VPN instance 2 are configured on edge node 1. VPN instance 1 is related to service packets. For example, the routing table of VPN instance 1 is used to record routes related to service packets. entry. VPN instance 2 is related to management packets, for example, the routing table of VPN instance 2 is used to record routing entries related to management packets. [0003] In order to save resources and reduce network deployment comp...
