Embodiment Construction
[0024] In order to realize the complete monitoring of OSPF network topology based on LSA information, a method for automatically detecting link interruption of OSPF routers is needed. Among the LSAs defined by the OSPF protocol, only the Router LSA and Network LSA describe the link information of the router. The Router LSA is generated by each router running the OSPF protocol, and is used to describe the link from its own router to the other party. The above-mentioned peer can be a neighbor router. Or multi-access network; Network LSA is generated by the DR on the multi-access network, and is used to describe the link from the multi-access network to the router on the network.
[0025]As mentioned in the background technology, Router LSAs cannot be collected by LSA collectors in some network topologies, so the method of automatically detecting OSPF router link interruption based on Router LSAs is not suitable for certain network topologies and LSA collector network access locat...
