The exhibit showing pings has wrong destinations. Should be pinging 10.1.1.x not 10.1.2.x
Diagram shows Client on the 10.1.2.0/24 network. but R2 fa 0/1 is configured for 10.1.1.1/24.
This question is also a bad example of summarization. R2 sees 10.1.1.0/24 as directly connected and connects to 10.1.2.0/24 using the summary router 10.0.0.0/8. R1 performs the same.
I am not sure what the problem is here but it is not caused by auto-summarization. Full network connectivity exists with the current configuration.
