A quite new feature for eigrp is the possibility of a leak-map. It’s simmiliar to the unsupress-map in BGP. As there is different behavior for the route-map statement if missconfigured, there is a way to send the summary and also all routes included in the summary.
ip summary-address eigrp 1 10.0.0.0 255.0.0.0 leak-map RM_LEAK
route-map RM_LEAK
An empty route-map will send the summary and also all component routes.
If the route-map is missing completelyit has no effect and the summary is send.
This would be a way to send the summary and also all components with the summary.
ip summary-address eigrp 1 10.0.0.0 255.0.0.0 leak-map RM_LEAK
ip prefix-list PRE_150 seq 5 permit 150.1.2.0/24
route-map RM_LEAK
match ip address prefix-list PRE_150
Like this only the summary 150.1.0.0/16 and the 150.1.2.0/24 network will be send to the neighbor.
