You need to watch out for your restrictions on the mask.  If you
have a restriction that all interfaces must be advertised with their
original mask, make sure you do not use the unless you are
allowed to use the ip ospf network point-to-point command under the
interface you are conneting with.  Again, this will fall under the
restrictions of how you can have your ospf neighbors talk to each other.

The best practice is to use the second method. By using wildcard
you are saying that I want to run OSPF routing process just on that
particular interface unless if you have a whole range of interface that
you want to use on the same line then you might want to use the first

Yes Its a good idea to use router-id under the routing process. Use
Loopback 0 as your router id's.

hi group,
I have a query that if a interface has an Ip address What
wild card bits should I use under the IGP process ?

router ospf 1
net  or

which is the best way ? What does Cisco expect from us ?

If not specified should I use a "router-id" under each IGP running on a
router ?
