are you running full bgp routes on the router that you want to put 6 areas
on.

Guy,
A router which belongs to multiple OSPF area's is called an Area
Border Router (ABR). All ABR's must belong to area 0 (The OSPF Backbone
area) in addition to any other areas they belong to. For each area a
router is a member of, it must store all of the LSA's for that area, and
participate in the Dykstra SPF calculations for that area. So, the more
area's a router is a member of, the higher the CPU and memory load on the
router. Recommendations for the maximum number of areas a router should
belong to vary. It isn't an exact science. The number of routers, the
number of circuits (networks), and the stability of the circuits in each
area will affect the max number of areas you can support on a single ABR.
That said, 6 areas plus area 0 on a single router is probably to high. 3-4
areas plus area 0 is generally a good rule of thumb. Again, keep in mind
there are many variables which affect how many areas a router can support
and so each situation must be considered individually.

Lets say you have a router with 6 DS3s, has anyone ever heard that it is
not
a good practice to have each DS3 be its own area? I was talking to someone
and they said that it may not be a good idea to have multiple areas on the
same router, but I have never heard that. Thanks.
