How to configure EIGRP to work with Discontiguous Networks

EIGRP is a classless Routing Protocol, but like RIP and RIPv2 it auto summarizes subnets to their classfull boundaries. So in the environment where you have Discontiguous Networks, EIGRP is not going to work until you prevent EIGRP manually from Auto Summarization.
Configuration is very simple, in fact only one command after you configure EIGRP Network i.e 

Router(config-router)#no auto-summary Router#Config t
Router(config)#router eigrp 50
Router(config-router)#network 10.0.0.0
Router(config-router)#no auto-summary
