Methods and devices for implementing Link Pass Through in a point-to-multipoint network in respect of the network reliability field are provided. Embodiments of the present invention are applicable to a network having an access gate, an access device, an aggregation device and a router. When a failure occurs in an active link between the access device and the aggregation device or between the aggregation device and the router, the access device breaks the connection between the access device and the access gate enables a standby link to conduct communication. Advantageously, when a failure occurs in the active link between the access device and the aggregation device or between the aggregation device and the router, the access device may break the connection between the access device and the access gate and the access gate may enable a standby link to conduct communication. Therefore, no matter what type of failure occurs, the embodiments of the present invention may enable a standby link to conduct communication, ensuring thereby communication reliability. |
