I want to block the redistribution of the 172.16.0.0/16 to the neighbor routers. Important is that I only wnat to block the 172.16.0.0/16 (supernet) but not subnets like 172.16.1.0/24, 172.16.2.0/24 and so on.
I am not quite sure which acl statement to use.
router eigrp 1111
distribute-list out 20
access-list 20 deny 172.16.0.0 0.0.0.0
access-list 20 permit any
Will this do the intented?
thank you for your help in advance.
