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
