Alright, time to get summarizing! Option B sounds like the way to go, keep those specific routes off R1's table.

I'm going with Option C. Summarization on both Level 1 and Level 2 routers should do the trick and keep R1 happy.

Option B seems the most logical choice. Summarization on the appropriate routers based on their levels should resolve the issue on R1.

Yes, configuring R3 for Level 1 and R6 for Level 2 summarization makes sense.
