Embodiment 1

[0051] The first embodiment of the present invention proposes a method for publishing routing information, such as figure 1 As shown, the specific process of this method is as follows:

[0052] Step 101: The VPN server of the virtual private network receives routing information released from the edge device PE of the first service provider, where the routing information includes VPN topology connection information corresponding to the first PE, and the VPN topology connection information Only the VPN identifier of the source end is included, and the VPN identifier of the source end is the first VPN identifier in the first PE;

[0053] Step 102: The VPN server selects the second PE as the destination;

[0054] Step 103: The VPN server selects a second VPN identifier matching the first VPN identifier from the VPN identifiers of the second PE according to the first VPN identifier, and adds to the VPN topology connection information The second VPN identifier, which is the VPN identifier...

Embodiment 2

[0128] Based on the same technical concept as the above method, the second embodiment of the present invention proposes a method for transmitting messages, such as Figure 5 As shown, the specific process of this method is as follows:

[0129] Step 501: The first PE receives the message sent from the source CE, and determines that the destination PE of the message transmission is the second PE according to the message sent by the source CE;

[0130] Step 502: The first PE selects the route publication information corresponding to the destination CE from the received route publication information of the second PE according to the IP address of the destination CE in the message, and receives The VXLAN tunnel encapsulation information corresponding to the destination CE is selected from the VXLAN tunnel encapsulation information of the second PE, where the route publishing information and VXLAN tunnel encapsulation information of the second PE are sent to the VPN server The first PE

Embodiment 3

[0150] Based on the same technical idea as the above method, the third embodiment of the present invention proposes an apparatus for publishing routing information, see Image 6 , The device includes:

[0151] The receiving unit 601 is configured to receive route announcement information from the first PE, where the route announcement information includes VPN topology connection information corresponding to the first PE, and the VPN topology connection information includes the VPN identifier of the source end. The VPN identifier at the source end is the first VPN identifier in the first PE;

[0152] The selection unit 602 is configured to select the second PE as the destination;

[0153] The route modification unit 603 is configured to receive the route publishing information sent by the receiving unit 601 and the second PE sent by the receiving selection unit 602, and select from the VPN identifiers of the second PE according to the first VPN identifier A second VPN identifier that...

Abstract

The invention discloses a method for issuing route information, a method and a device for transmitting a message. The method for issuing the route information comprises the steps of receiving route issuing information issued by a first PE (Provider Edge) by a VPN (Virtual Private Network) server, and selecting a second PE which is used as the VPN mark of a destination end by the VPN; selecting a second VPN mark which is matched with a first VPN mark from VPN marks of the second PE by the VPN server according to the first VPN mark, adding the second VPN mark which is used as the VPN mark of the destination end in VPN topological connection information, and obtaining modified route issuing information; determining VXLAN (Virtual Extension Local Area Network) tunnel encapsulation information that the message is transmitted to the first PE by the second PE by the VPN server according to the first VPN mark and the second VPN mark; sending the VXLAN tunnel encapsulation information and the modified route issuing information to the second PE by the VPN server.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for issuing routing information and a method and device for message transmission. Background technique [0002] The existing Virtual Private Network (VPN for short) usually requires the use of Multi Protocol Label Switch (MPLS) technology, while VPN is a remote access technology that uses public network links to set up a private network, usually through Different autonomous systems (Autonomous System, referred to as AS), because VPN essentially uses encryption technology to encapsulate a data communication tunnel on the public network, so that the security performance of the message transmission through the VPN can be improved. [0003] However, when the existing VPN is performing route publishing, the publishing end transmits the routing information of the publishing end to the router connected to the publishing end, and the router forwards the routing inf...
