Question NB71 - EIGRP Summarization
#4
I just looked this up and think I can clear up the confusion. According to Cisco Academy material:

"An EIGRP router autosummarizes routes ONLY for networks to which it is attached"

So, RT1 (no auto-summary) sends the 10.10.10.0/24 network to RT2. RT2, since it is NOT attached to 10.10.10.0 (or 10.0.0.0 for that matter) passes the classless address to RT3. It does not auto-summarize the 10.10.10.0/24 network because it is not attached to that network.

Hope that clears this up.
