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
