Problems solved by technology

Apparently, the disadvantage of the prior art is that a large amount of unused virtual private network routing information is transmitted between PE1 and PE6, which consumes a large amount of backbone network bandwidth resources, resulting in a waste of network bandwidth resources; in addition, between PE1 and PE6 Every time a session passes between them, the data must be sent to the transport layer for processing, which will also increase the processing burden of the intermediate devices (PE2, PE4)

Embodiment 1

[0034] Such as image 3 As shown, this figure is a flow chart of the PE communication method in Embodiment 1 of the present invention, and its specific steps are as follows:

[0035] S101: Initially configure a BGP instance on PEs in the network.

[0036] Such as Figure 4 As shown, a BGP instance is configured for PE1, PE2, PE3, PE4, PE5, and PE6 respectively. For PE1, PE2, and PE3 in AS1, the two BGP instances are configured as IBGP peer relationships; similarly, for For PE4, PE5, and PE6 in AS2, an IBGP peer relationship is configured between the two BGP instances; for PE2 and PE4, an EBGP peer relationship is configured between the two BGP instances.

[0037] As mentioned above, the backbone network consists of two domains AS1 and AS2, which provide VPN services for users. The same VPN1 is configured on PE1 and PE6, and VPN1 is connected to CE1 and CE3 respectively; VPN2 is also configured on PE1 to provide VPN services for CE5; VPN3 is also configured on PE6 to provide...

Embodiment 2

[0062] The concrete steps of embodiment 2 of the present invention are as follows:

[0063] S201: Initially configure a BGP instance on PEs in the network.

[0064] S202: The PE diffuses the pre-configured information of at least one VPN-ID according to the initial configuration BGP instance.

[0065] S203: After receiving the VPN-ID information, the PE judges whether it is configured with the same VPN-ID according to the information, and determines PEs with the same VPN-ID.

[0066] S204: PEs with the same VPN-ID automatically establish a corresponding BGP instance.

[0067] S205: After the PE finishes establishing the BGP instance, select one of the BGP instances as a HUB-BGP instance, and establish an IBGP peer relationship or an EBGP peer relationship between the HUB-BGP instance and other BGP instances.

[0068] After the PEs with the same VPN-ID complete the establishment of BGP instances, select one of the BGP instances as the HUB-BGP instance, such as Figure 4As sh...

Embodiment 3

[0072] The concrete steps of embodiment 3 of the present invention are as follows:

[0073] S301: Initially configure a BGP instance on PEs in the network.

[0074] S302: The PE diffuses the pre-configured information of at least one VPN-ID according to the initial configuration BGP instance.

[0075] S303: After receiving the VPN-ID information, the PE judges whether it is configured with the same VPN-ID according to the information, and determines PEs with the same VPN-ID.

[0076] S304: PEs with the same VPN-ID automatically establish a corresponding BGP instance.

[0077] S305: After the PE completes the establishment of the BGP instance, select one of the network devices in the network to establish a new BGP instance, and use the new BGP instance as the HUB-BGP instance. The HUB-BGP instance and the established BGP instance are established. IBGP peer relationship or EBGP peer relationship.

[0078] After the PEs with the same VPN-ID complete the establishment of the BG...

Abstract

The invention relates to the field of network communication technology, in particular discloses a communication method for service supplier network edge equipment. The method comprises the steps as follows: at least one virtual private network identifier VPN-ID information which is severally preset is scattered among service supplier network edge equipment PE; the PE with the same VPN-ID in the network is confirmed according to the scattered information; the PE with the same VPN-ID automatically establishes a corresponding border gateway protocol BGP example; the BGP example is used for alternating virtual private network router information which is corresponding to the VPN-ID among the PE with the same VPN-ID. The invention also provides a PE which is used for transmitting the virtual private network router information. So the invention is capable of effectively saving network bandwidth resource.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a communication method of a service provider network edge device in the field of transport network technology, and a service provider network edge device for transmitting virtual private network routing information. Background technique [0002] With the rapid development of network interconnection technology and communication requirements, VPN (Virtual Private Network, virtual private network) came into being according to the needs of network customizers to manage network resources. The rapid development of Internet technology and the continuous promotion of its application fields have made many departments (such as the government, the military, multinational companies, and between companies) increasingly consider using cheap public infrastructure communication facilities to build their own private wide area networks. To carry out the safe transmission of data in t...
