During operation, the computer network device may receive an instance of a message from a second computer network device in a network via a port (such as a router port) associated with a link between the computer network device and the second computer network device. Based at least in part on the received instance of the message, the computer network device may identify the port as being a type of port (such as a passive neighbor port and a non-edge port in the network), and may not forward the instance of the message to one or more additional computer network devices via one or more additional ports (such as one or more additional router ports)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Port discovery via passive internet group management protocol snooping neighbors","description":"A computer network device (such as a switch or a router) that implement a passive snooping communication protocol is described.
