Yes this is true and I have gotten in the habit of using this method, however
it seems faster using copy and paste with the second method. Also it really
does just come down to preference on what works for you

The more specific network statement ensures that you are advertising only out
the links that you specify
150.100.24.X 0.0.0.0 - includes the indentified link ONLY
150.100.24.0 0.0.0.255 - may advertise more than you want.
I always do the following (providing the requirements have no restrictions)
R1
router ospf 1
router-id 1.1.1.1
network 150.100.24.X 0.0.0.0 area X
passive-interface default
no passive-interface [interfaceX/X]

There is no difference, it really just a matter of preference. However in the
actual exam it may come down to speed. If you are using notepad to copy/paste
using the 150.100.24.0 0.0.0.255 is faster but it's really up to you.

Subject: [OSL | CCIE_RS] Network Advertisements.
Example :
R1 S0/0/0 : IP address is 150.100.24.2 / 24
R2 S0/0/0 : IP address is 150.100.24.4 / 24
lets say we want to enable OSPF on this segment, so would it make any
difference if we type on R1 :
router ospf
network 150.100.24.2 0.0.0.0 area 0
OR
router ospf
network 150.100.24.0 0.0.0.255 area 0
Becuase i have seen both during configurations , is there any recommendations
which syntax we should use and why ? and can i always make it 0.0.0.0 with
exact IP except in the LAN environments ?
