I hope I understand it correct...

auto-summary will only work when the routing information
passes a major network boundary.

In the following example there is NO major network boundary
and R2 would not perform auto-summary (when running RIP or EIGRP)

R1----- 10.10.2.4/30----R2------10.2.2.0/30------R3

In the next example there is a major network boundary and R2 would
perform auto summarization to the classfull network 10.0.0.0/8

R1-----10.10.2.4/30----R2------192.168.2.0/30-----R3
