摘要： A reliability processing method and system in networking of Metro Ethernet Network providing multi-service are provided. The method includes: establishing a Virtual Router Redundancy Protocol (VRRP) group with at least two service control gateways, establishing network connections between an access device (UPE) and the service control gateways in the Virtual Router Redundancy Protocol group by a Virtual Private LAN Service (VPLS); establishing Layer 2 service and Layer 3 service connections between an active service control gateway and the Access device after active and standby service control gateways in the Virtual Router Redundancy Protocol group are determined according to a processing result of a Virtual Router Redundancy Protocol message, and performing Layer 2 service and Layer 3 service processing. With the present invention, when the MAN service is in fault, all the Layer 2 and Layer 3 services may be switched to the standby service control gateway quickly, and the switching may be on the order of milliseconds. Therefore, the reliability of the Layer 2 and Layer 3 services of the MAN may be sufficiently guaranteed, and the overhead of the system may be reduced significantly.
