Embodiment Construction

[0042] In the current EVI No Flooding mode, unknown unicast packets are only broadcast on the local PE device, and members in the Extended VLAN of the local user can receive the broadcast packets, but for members in the Extended VLAN on the remote PE device Then the message cannot be received.

[0043] In order to solve the above problems, in the embodiment of the present invention, in the EVI No Flooding mode, the PE device is selected as the Extranet PE device (referred to as the Internet PE device) among the PE devices with the GRE tunnel established. Select a PE device among the PE devices of the GRE tunnel as the extranet PE device, and usually select the PE device with a large-capacity MAC address table as the extranet PE device. Preferably, the Extranet PE device maintains all MAC address information in the entire EVI instance; other PE devices (for the convenience of description, the embodiment of the present invention refers to PE devices other than the Extranet PE de...

Abstract

A network access apparatus comprising a tunneling interface to collect device access information of network devices of a first computer network having a first network gateway device and device access information of network devices of a second computer network having a second network gateway device, wherein the apparatus is to send device access information of network devices of said first computer network to said second computer network upon receipt of an inquiry for request of device access information from said second computer network, and vice versa.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message transmission method and equipment, which are applied to EVI networking. Background technique [0002] EVI (Ethernet Virtual Interconnection, Ethernet connection virtualization) is an Ethernet interconnection technology that can deploy multiple data centers in different places to achieve load sharing and high reliability, and freely migrate between data centers through virtual machines . [0003] The overall EVI network consists of a core network (public network) and a site network (private network). The site network is a Layer 2 network with independent business functions connected to the core network through one or more edge devices, including the edge network (aggregation The network between the device and the edge device) and the access network (the network between the access device and the aggregation device), mainly composed of hosts and switching devices; ...
