JN0-351 · Question #26
You are an operator for a network running IS-IS. Two routers are failing to form an adjacency. What are two reasons for this problem? (Choose two.)
The correct answer is B. There is no configured ISO address on any IS-IS interface. IS-IS requires each router interface D. The family iso configuration is missing from the adjacency interface. The 'family iso'. The two reasons for the failure to form an adjacency in a network running IS-IS could be: to have an ISO address configured. Without this address, the routers cannot form an adjacency. configuration is essential for IS-IS to function correctly. If this configuration is missing…

Explanation
The two reasons for the failure to form an adjacency in a network running IS-IS could be: to have an ISO address configured. Without this address, the routers cannot form an adjacency. configuration is essential for IS-IS to function correctly. If this configuration is missing from the adjacency interface, it could prevent the formation of an adjacency. These explanations are based on the Enterprise Routing and Switching Specialist (JNCIS-ENT) documents and learning resources available at Juniper Networks.
