Abstract: This application discloses an information notification method and a related apparatus. The Ethernet storage system includes a first switching device and a first node, and the first switching device is an access device of the first node. The first node sends a join message to the first switching device. The join message includes an identifier of the first node and configuration information of the first node. The first switching device receives the join message, obtains the identifier of the first node based on the join message, determines, based on the identifier of the first node, a first zone corresponding to the first node, and sends a join notification message to a second node that belongs to the first zone. The join notification message includes the identifier of the first node and the configuration information of the first node.

Abstract: A first network device obtains first information. The first information indicates that a first link is faulty, and the first link is a link between any two network devices in a network system to which the first network device belongs. The first network device sends the first information to a second network device by using BGP, for example, sends a link fault message to the second network device by using BGP. The link fault message carries the first information. The second network device is a neighbor device of the first network device. The first network device determines an unreachable route in a routing table of the first network device based on the first information and a topology of the network system. A path corresponding to the unreachable route includes the first link. The first network device marks the unreachable route as invalid.
