!!User Comments on Implementing OSPF
[Isomer] says to stick everything in area 0, <shrug> so do it his way ok..
+
PerryLorier: Yeah, because dealing with area's is a bitch, and if you are just learning, stick everything in area 0, when your network gets large enough that convergance times are starting to become a worry, think about different areas then, but before that time, stick everything in area 0 and you'll save yourself a lot of hassle. Also, remember that Area 0 is "special" to [OSPF], so if you decide to use area 42 or whatever, it __will__ break.
-LindsayDruett: Dealing with multiple areas is not really that bad, however, all Areas __must__ connect directly to Area 0, that is because Area 0 is the __backbone__ Area. If you __really__ can't meet the requirements of directly connect to Area 0 and have to go through another area, you can insert a __''Virtual Link''__ - ''It is not a recommended strategy.''

+
+It is good practice to configure a Loopback Interface (other than 127.0.0.1) on your OSPF router and use that Loopback interface for the OSPF RouterID. Also it is a good idea to configure it as the OSPF Router ID rather than letting the router discover that address as the OSPF RouterID
+
+It is also good practice to limit each area to 50 routers, make sure that each router has no more than 60 neighbors, that neighbor is spelled the American way, each Area Border router doesn't have more than 3 areas, and that you set the OSPF priority so that it doesn't get elected as a DR or BDR for more than 1 network.
-Yes... Definitely more coming
