EIGRP Notes – Route Filtering
As always, correction are encouraged.
You can configure an EIGRP router to filter routes from being advertised or from being accepted.
Objective: Filter out the route to 10.0.254.1/32 from being advertised to the rest of the network via EIGRP.
ip prefix-list PRE1 deny 10.0.254.1/32 ip prefix-list PRE1 permit 0.0.0.0/0 le 32 ! router eigrp 1 distribute-list prefix PRE1 out -- OR -- ip access-list standard ACL1 deny 10.0.254.1 0.0.0.255 permit any ! router eigrp 1 distribute-list ACL1 out

Thanks for this post, I just would like to be sure about the ACL solution, is it correct “deny 10.0.254.1 0.0.0.255” for a /32? or would it be “deny 10.0.254.1 0.0.0.0”? I have a doubt.
Thanks in advance!
