摘要

The method and system of the reliability processing Metro Ethernet to provide a multi-function network service group (registered trademark) networks, including the two service routers at least make up a virtual router redundancy protocol group. Using a virtual private LAN service, network connection relationship is created separately during the service router of the virtual router redundancy protocol group and user side provider edge router. And backup services router and the main service router is determined in accordance with the processing result of the virtual router redundancy protocol message, the connection is created between the service router, and the third layer and the second layer of the user side provider edge router, then, the main third layer services and service second layer of service router is processed. When the network is not working, it can be promptly switched to the backup service router service layer 2 and layer 3 of all, the present invention is less than 1 second switching time interval. Thus, the present invention may be able to ensure the reliability of the service layer 2 and layer 3 Metro in an Ethernet network, and to reduce the cost of the system.
