An engineering team implemented IS-IS on the network, with several different areas. Recently, router R6 in area 3 has been experiencing excessive CPU usage. To reduce the load, a network engineer implemented route summarization on R2. However, R6 is still receiving the full routes from all routers. Which action must the engineer take to resolve the excessive CPU usage?

  • A. Configure all routers as Level 1/2 routers so that route summarization functions throughout the network.
  • B. Configure routers R3 and R5 to send summary routes to R6.
  • C. Configure the Level 2 router R6 to manage summarization for the network.
  • D. Configure router R1 to send only the default route to R2 and R4.

Selected Answer: B
R1-2-4 have no adjacency to R3-5 because no L1 adj between different areas, how is R6 receiving full routes from all routers to begin with? Am I missing something? Summarization is done on border so B makes the most sense
