asked on Filtering with Route Map and prefix-list
I have EIGRP routes advertised from R1 to R2 as shown below:
on R1 I have configured route map and prefix list to block (filter out)network 172.16.0.0 /16 le 26, but it does not seem to work
Any Help ?
thank you

on R1 I have configured route map and prefix list to block (filter out)network 172.16.0.0 /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 172.16.0.0/16 le 26
route-map FILTER_OUT permit 20
Any Help ?

router eigrp 1
network 0.0.0.0
distribute-list route-map FILTER_OUT out
no auto-summary
I did not have the Distribute-List in my Configuration. Do I have to add it ?
