Filtering with Route Map and prefix-list

Last Modified: 2017-11-18
I have EIGRP routes advertised from R1 to R2 as shown below:

R2#sh ip route eigrp 1      is variably subnetted, 13 subnets, 7 masks
           [90/156160] via, 00:00:09, FastEthernet0/0 is subnetted, 1 subnets
D [90/156160] via, 00:00:09, FastEthernet0/0 is variably subnetted, 5 subnets, 3 masks
D [90/156160] via, 00:00:09, FastEthernet0/0
D [90/156160] via, 00:00:09, FastEthernet0/0
D [90/156160] via, 00:00:09, FastEthernet0/0
           [90/156160] via, 00:00:09, FastEthernet0/0
           [90/156160] via, 00:00:09, FastEthernet0/0

on R1 I have configured route map and prefix list to block (filter out)network /16 le 26,  but it does not seem to work

route-map FILTER_OUT deny 10
 match ip address prefix-list SMALL_PREFIXES
ip prefix-list SMALL_PREFIXES seq 10 permit le 26

route-map FILTER_OUT permit 20

Any Help ?
