To answer you question think of the actual function of the network
command!!! The "network area" command in OSPF is "to define the interfaces
on which OSPF runs and to define the area ID for those interfaces" All the
mask feature of this command does is enable you to enable a group of
interfaces in one line. So..... it really doesn't matter how you define
interfaces to participate in OSPF as long as you do it.

Subject: router configs/OSPF - interfaces or entire networks?
I have noticed in some lab scenarios that when the instructions say that a
router interface should be advertised in a routing protocol, the labs
sometimes advertise only the interface, othertimes an entire subnet.
For example, let's say it's an ethernet interface with address
192.168.1.1/24 being advertised under OSPF. I've seen the following:
router ospf 64
net 192.168.1.1 0.0.0.0 area 0
or
router ospf 64
net 192.168.1.1 0.0.0.255 area 0
I wouldn't be concerned if there were some consistency. I've seen the lab
instructions state "interface" and then seen the entire network advertised
and vice-versa.
Any thought?
