The correct answer is D. Configure the same IS-IS level on both routers. In IS-IS, an adjacency forms only between routers that participate at the same IS-IS level (Level-1 or Level-2). If one router is running only Level-1 and the other only Level-2, they will never establish adjacency, hence the “No adjacency found” message. Ensuring both R1 and…
Question
Refer to the exhibit. A growing company with multiple internal networks asked the network- engineering team to improve communication between its internal networks, focusing on efficient data exchange. A network engineer is configuring IS-IS for route advertisement between routers R1 and R2, which are situated in different AS. The engineer configured R1 with IP address 192.168.1.1 and R2 with IP address 192.168.1.2 In accordance with RFC 1195 and IEEE 10589 standards. However, the routers failed to establish IS-IS adjacency via their GigabitEthernet0/0 interfaces. The engineer checked the cables and interfaces for any faults that might affect physical connectivity and verified the uniqueness of the routers’ system ID. Which action must the engineer take to resolve the issue?

Explanation
In IS-IS, an adjacency forms only between routers that participate at the same IS-IS level (Level-1 or Level-2). If one router is running only Level-1 and the other only Level-2, they will never establish adjacency, hence the “No adjacency found” message. Ensuring both R1 and R2 are configured for the same IS-IS level on Gi0/0 resolves the issue.
