Also, when you tested this in your lab, did you confirm your EIGRP neighbor relationship? For example, if you haven’t statically configured R1 and R2 as being neighbors, you must include the network segment they share as part of the network statement under the EIGRP process.
You can verify your routers have neighbors by doing the following:
R2#sh ip eigrp neighbors
EIGRP-IPv4 Neighbors for AS(1)
