Don't you need to use the command no auto-summary with EIGRP.

Ok so to further expand on that, let's say I have the config below:

interface Ethernet0/0
ip address 192.168.1.17 255.255.255.248

inteface Ethernet0/1
ip address 192.168.1.33 255.255.255.248

If I only want to advertise Ethernet0/0 via EIGRP, but not Ethernet0/1.

I must filter within the EIGRP process to stop 192.168.1.32 /29 from being
advertised?

EIGRP 1
network 192.168.1.0
distribute-list 1 in

access-list 1 permit 192.168.1.16

Is this correct? Wildcard masks are much easier.
