I assume you're talking about the Halo 3 multiplayer that's included in ODST...
The multiplayer disc is essentially a Halo 3 disc without the campaign. As long as you're playing with the same account, your rank is the same, because it would be like going to a store and just buying a new Halo 3 disc and playing it.
