With EIGRP, when you enter the network command within the routing process, it doesn't advertise what is specified by the command, but rather advertises the interfaces that fall within what is specified by the network command.

Consider the following WAN links

int s0/0

ip addr 192.168.30.5 255.255.255.252

int s0/1

ip addr 192.168.30.9 255.255.255.252

Within the EIGRP routing process, the following command would include both interfaces and advertise both /30 networks

network 192.168.30.0

If you would like to only advertise one of the links, or be more specific, the following would only advertise the network on interface s0/0

network 192.168.30.5 0.0.0.3

Make sense?
