Method and device for implementing multirole host computer

Abstract

The invention discloses a method for implementing a multirole host computer. The method comprises the following steps that: source PE equipment receives a message from the multirole host computer in multirole examples; the source PE equipment learns an MAC address of the multirole host computer from the multirole examples according to the message; the source PE equipment synchronizes the MAC address of the multirole host computer to a target example and transmits the message to other PE equipment, and the target PE equipment returns a response message to the source PE equipment in the target example according to the message; and the source PE equipment acquires the MAC address of a target host computer from the response message in the target example, and synchronizes the MAC address of the target host computer to the multirole examples and the target example. In the method, the multirole host computer is implemented on two layers under VPLS network environment and PBB network environment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for realizing a multi-role host. Background technique [0002] MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) is a system for fast data packet switching and routing, which can provide destination, routing, forwarding and switching capabilities for network data traffic; due to the networking characteristics of MPLS, It is very suitable for setting up VPN (Virtual Private Network, virtual private network). In the MPLS VPN network, CE (Custom Edge, user edge) equipment, PE (Provider Edge, backbone network edge) equipment, P (Provider, backbone network) equipment, etc. are included. [0003] Specifically, in an MPLS VPN network, usually, the CE device is associated with the corresponding VRF (Virtual Routing Forwarding, VPN routing forwarding table) through a specific interface, that is, all the PE devices connected to the PE device t...

Problems solved by technology

[0017] Existing multi-role host implementation solutions are all aimed at the networking environment of MPLS L3VPN, and for Layer 2 network environments such as VPLS (Virtual Private LAN Service, virtual private local area network) and PBB (Providerbackbone bridge, operator backbone bridge), The multi-role host implementation scheme cannot be realized, and the multi-role host cannot access devices in other VSI (Virtual Switch Instance, virtual switch instance) instances

[0018] However, in the actual VPLS and PBB Layer 2 network environment, the requirements for multi-role hosts are still required in many cases. For example, in banking systems, financial systems of large companies, and public service systems of companies, multiple branches Hosts in different VSI instances need to access the same system resources, and the system resource server must also be able to access hosts in different branches; it can be seen that the hosts in this branch have the requirements of multi-role hosts, and now Some VPLS and PBB deployments fail to meet the requirements of multi-role hosts
