Disclosed are a method, device and system for preventing network node ageing. The method comprises: it is analysed whether a control plane of a first node has exited a hello detection function due to malfunction; in the case that the control plane of the first node has not malfunctioned but has exited the hello detection function, a specific identification is added to a first interaction message, the specific identification being used to indicate the state that the control plane has not malfunctioned but has exited the hello detection function; the first interaction message is sent to a second node neighbouring the first node, so that the second node, via the specific identification, determines that the control plane of the first node has not malfunctioned but has exited the hello detection function, and continues to send a refresh message to the first node. |
