Abstract

This application provides a gateway access method and device in an Ethernet virtualized interconnection EVI networking. Wherein, all EDs in the EVI networking are used as gateway devices, and are configured with the same IP address and MAC address. Any ED determines the corresponding route according to the destination IP address of the data message received from the public network side. The outgoing port of the EVI LINK is used to encapsulate the data message through the IP over IP GRE tunnel and send it through the outgoing port; and the data message encapsulated by the IP over IP GRE tunnel is received through the EVI LINK, and the encapsulation of the data message is ejected Determining a route for forwarding the data message according to the destination IP address of the data message, and forwarding the data message encapsulated by the IP GRE tunnel through the egress port in the determined route. This not only realizes the normal access of services, but also realizes the seamless migration of hosts in the EVI networking.

Description

technical field

[0001] The present application relates to network communication technology, in particular to a gateway access method and device in an Ethernet Virtualization Interconnection (EVI: Ethernet Virtualization Interconnection) networking. Background technique

[0002] Ethernet Virtualization Interconnection (EVI: Ethernet Virtualization Interconnection) is an Ethernet interconnection technology that can deploy multiple data centers in different places to achieve load sharing and high reliability.

[0003] The technical terms involved in EVI networking are explained below:

[0004] Edge device (ED: Edge Device), which is used to forward packets from the private network to the public network, and from the public network to the private network.

[0005] An EVI instance (instance), also known as a virtual interworking instance, is uniquely identified by a network ID (Network ID). Packet forwarding in different EVI instances is isolated from each other.

[0006] Virtu...
