Re: EIGRP passive-interface question

My understanding is that passive-interface prevents hellos on the
interterface while allowing protocols to advertise the network to
neighbors. If you want to prevent the neighbors from receiving updates
about the 172.16.5.0, use an outbound distribute-list.

router eigrp 1
network 172.16.0.0
distribute-list 1 out ethernet 1
passive-interface ethernet 0
!
ip access-list 1 deny 172.168.5.0 0.0.0.255
ip access-list 1 permit any

Given the following configuration, will EIGRP advertise the network on
ethernet 0?

int e0
  ip address 172.16.5.5/24

int e1
  ip address 172.16.6.6/24

router eigrp 10
  network 172.16.0.0
  passive-interface e0

According to CCbootcamp lab 18, it should not. According to the Cisco
documentation at the following link, it will.

When I was doing the lab 18 I couldn't get the network under the passive
interface to disappear. Does anyone know how to keep the 172.16.5.0/24
network from being advertised using passive interfaces?
