Remember Ben - the network statement and the wildcard mask has nothing
to do with what you advertise for IGPs. It is indicating what interfaces
should run the protocol.
I love to use 0.0.0.0 to be specific about what exact interfaces will
run that protocol. While it can be more typing - I rest at ease knowing
that I have not inadvertently run the protocol on interfaces causing me
to potential lose points in the lab.
When you get to BGP - the network statement is different - now it is
indicating what you advertise.
It looks like Cisco wants to move away from the use of the network
statement in IGPs - that is why more and more protocols feature an
interface configuration....

So that you only refernce the exact IP Address and not the entire
subnet. It
is more explicit. Be careful when reading questions as some may
actually ask
for one or the other.

Subject: IE sampe lab v4 - OSPF/EIGRP networks?
going
through the solutions guide for v4 of the sample lab, I'm wondering why
all
the ospf/eigrp network statements have a wildcard mask of 0.0.0.0
For the
loopbacks I can see this (because the question asks to advertise the
loopback
INTERFACE address not the NETWORK address), but for the physical
interface
subnets they are al /24, so why aren't we saying 0.0.0.255?
