OSPF suggestion please

Hello everyone! I have a thing concerning OSPF, and best deployment of it. Let’s say I have a ring network and a bunch of routers connecting to it (usually for PPPoE users). One of the routers in backbone is gateway. And of course other routers (not in backbone) only need to know the way to gateway. I’d like to ask for suggestions where should I deploy OSPF, only in backbone, as one AREA, or many areas of OSPF connecting to each other, like I presented in the file. Is the OSPF right solution for this kind of network? Should I maybe put OSPF only in backbone, and outside of it leave static or RIP routes? What would be the best solution for you?
Another question is, is it possible that routes from one area (not including backbone) doesn’t know about other areas. Because I guess it could cause unnecessary routes on some MTs. E.G.Some router in AREA 6 doesn’t need to know about PPPoE routes in any other area, only the backbone. How could I achieve this? Is it by including certain interfaces, certain networks or? The primary reason for this ring network is backing up routes to gateway. And of course less time spending typing static routes on every MT.

Thank you very much for your time and willing to help. I read of course bunch of tutorials and manuals, but I need specific suggestion for this topology. Thank you again.

Leave backbone area on the center of your network and then configure smaller areas, just like in your diagram.
You can set then area type to stub and ospf will not import unnecessary routes in that area.

uuu, great!:smiley: Thank’s very much!:wink: So I was, indeed on the right way:D

Have a nice day!:wink:

Hello!

One more thing considering this scheme please…
My gateway router should be out of the backbone area, and also should have insight of all routes in the network, all areas (RB 1000 e.g.). Am I right with this one?
Can I do it by adding gateway in the separate area, because gateway should know about all routes in all areas. Am I on the right track? Or you have other proposition?
Thank you!
