What routes will R3 learn from R2 through EIGRP?

Refer to the exhibit. In this network, R1 is configured not to perform auto summarization within
EIGRP. What routes will R3 learn from R2 through EIGRP?

A.
172.30.1.0/24 and 10.1.2.0/24; EIGRP only performs autosummarization at the edqe between
two major networks.

B.
172.30.0.0/16 and 10.1.2.0/24; R2 will perform autosummarization, although R1 will not.

C.
Since R2 is configured without autosummarization, it will not propagate the 172.30.1.0/24 route.

D.
172.30.0.0/8 and 10.0.0.0/8

Explanation:
EIGRP performs an auto-summarization each time it crosses a border between two different major
networks. For example, in the topology below R3 will auto-summary and advertise only 10.0.0.0/8

network to R4 router.
