Which two configurations will fix it?

An engineer configured a leak-map command to summarize EIGRP routes and advertise specifically loopback 0 with an IP of 10.1.1.1 255.255.255.252 along with the summary route. After finishing configuration, the customer complained not receiving summary route with specific loopback address.

Which two configurations will fix it? (Choose two)
A . Configure route-map Leak-Route permit 10 and match access-list 1
B . Configure access-list 1 permit 10.1.1.1 0.0.0.252
C . Configure access-list 1 and match under route-map Leak-Route
D . Configure route-map Leak-Route permit 20
E . Configure access-list 1 permit 10.1.1.0 0.0.0.3

Answer: A E

Explanation:

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

The below commands will fix the configuration 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
