Hey, why don't we just have R3 and R6 do the summarization? Spread the workload a bit, you know?

Option B seems like the way to go. Summarizing at the Level 1 and Level 2 routers should do the trick.

Agreed, summarizing at both Level 1 and Level 2 routers sounds like the best solution.

But wouldn't it be better to configure R6 only to perform summarization for all routers?

I disagree. I believe we should configure R3 to perform summarization for Level 1 routers, and configure R6 to perform summarization for Level 2 routers.
