<p>A linkage method of links and a communication device are provided which, according to the determination whether the route table entry indicating forwarding is invalid, can trigger the closing of the downlink associated with the route. By using the utility models which are provided, the downlink is associated with the more mutable route table entry, and the defect that the closing of the downlink can not be triggered when the physics uplink is still in good condition can be avoided. By monitoring one or more route table entries, when the focused route table entry is invalid, the link bound with it beforehand is closed in order to inform the downstream device of rechosing the forward link to implement the fast converging of the whole network.</p> |
