Answer: AD

Explanation:

When you configure an EIGRP summary route, all networks that fall within the range of yoursummary are suppressed and no longer advertised on the interface. Only the summary route isadvertised. But if we want to advertise a network that has been suppressed along with thesummary route then we can use leak-map feature.

The below commands will fix theconfiguration in this question:

R1(config)#access-list 1 permit 10.1.1.0 0.0.0.3

R1(config)#route-map Leak-Route permit 10 // this command will also remove the “route_map

Leak-Route deny 10” command.

R1(config-route-map)#match ip address 1
