METHOD FOR DETECTING INTERFACE FAILURE AND NETWORK NODE EQUIPMENT

摘要

A method for detecting interface failure is disclosed. The method includes: building BFD sessions on every member link and carrying out BFD detection, reporting the faulty state of the link to the interface when a fault of the link is detected, determining whether the interface is failure according to the faulty states of the member links received by the interface. A network node device is also disclosed. Then the efficient detection for various kinds of interface is implemented by detecting the member links of the interface directly.
