Just for additional info: depending on the task requirements, you have 2
methods to achieve the objective:
Method1- very simple
---------------------
route-map LeakList permit 10
match ip address 1
!
access-list 1 permit 10.1.1.0
!
interface Serial0/0
ip summary-address eigrp 1 10.1.0.0 255.255.0.0 leak-map LeakList
Method2
--------
router eigrp 100
redistribute static route-map aggroutes
default-metric 1000 1 255 1 1500
distribute-list 20 out serial0/0
!
ip route 10.1.0.0 255.255.0.0 null0
!
route-map agg-routes permit 10
match ip address 10
match interface serial 0/0
!
access-list 10 permit 10.1.0.0 0.0.255.255
access-list 20 permit 10.1.1.0 0.0.255.255
