In which case when I configure the OSPF routing protocol, I have to use ip address or network address ?,,,,example, if the the ip address for serial interface for R1 is 192.168.1.1/24,,,when I configure OSPF I am going to do this :
as a matter of fact, it depends what you want to achieve. If you want to advertise just one interface, you would use the 0.0.0.0 mask. If you want to advertise a range of interfaces, you would use the wildcard mask accordingly...
If you know the difference between the two you should then know when to use each format.
using network 192.168.1.0 0.0.0.255 area 0
network 192.168.1.1 0.0.0.0 area 0
will have the same result in the case there is only one interface falling in that range like in your scenario but if you had two interfaces, one with 192.168.1.1/25 and one with 192.168.1.129/25 then the result would be different. The first format would attach two interfaces to the ospf process whereas the second format would only attach one.
Hope this helps,

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
