Problems solved by technology

When Server1 accesses the external network host1, the destination MAC of the message is the MAC address of ED1, and the destination IP address is the address of host1. When the message is sent from ED2 to ED1, it is a message in Ethernet over IP GRE encapsulation format. ED1 must first terminate the IP GRE tunnel, and then perform IP search to obtain the

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] In the embodiment of the present invention, a single gateway is used in the EVI network, and one ED in the EVI network is configured as a gateway. For ease of description, the ED configured as a gateway is called a gateway ED, and other EDs are called ordinary EDs. The exchange of packets between the site network and the core network is forwarded through the gateway ED.

[0023] see figure 2 , figure 2 It is a flowchart of a virtual machine smooth migration method in an EVI network according to an embodiment of the present invention, including the following steps:

[0024] Step 201, establishing a redundant tunnel between the common ED and the gateway ED for carrying IP packets, and configuring the MAC address of the gateway ...

Abstract

According to an example,virtual machine(VM)migration may include generating a redundant tunnel between a common edge device(ED)of a plurality of common EDs of a multi-site network(MSN)and a gateway ED of the MSN.A gateway media access control(MAC)address and a static route may be configured for forwarding an Internet protocol(IP)message between the common ED and the gateway ED using the redundant tunnel.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for smooth migration of a virtual machine in an Ethernet Virtual Interconnection (EVI) network. Background technique [0002] The EVI network consists of a core network (public network) and a site network (private network), where the site network is connected to the core network through its own edge network (ED). EVI implements the extension function of VLAN between different site networks. These expanded VLANs constitute independent EVI network instances, and the forwarding in VLANs of different EVI network instances on a device is isolated from each other. [0003] The smooth migration of virtual machines needs to be implemented in the EVI network. see figure 1 The schematic diagram of the EVI network shown in the figure, such as figure 1 As shown, site network 1 includes Sever1 (IP: 10.1.1.10, gateway: 10.1.1.1) and Sever2 (IP: 10....
