eigrp and leak-map

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.
