Enterprise level select EIGRP.
ISP level prefer OSPF or ISIS and alos if they have BGP/MPLS in the cloud.
is it simple now?

Subject: Re: [OSL | CCIE_RS] OSPF Design Question
A lot of different things come into play here. If this is a simple topology
there is no reason we can't have area 0 for everything. If you have a ton of
routes going back and forth between the sites, you may make each site an area
and leave area 0 for the core and distribution. With that design you would
just have type 3 summary LSAs going between the areas.
If you are running point-to-point subinterfaces you will not have a DR and you
will not have to deal with priority at all. At the end of the day, it is more
of a design decision depending on your environment!

Why are you set on using OSPF and not something like EIGRP? It seems like you
have a cisco only environment and typically OSPF is deployed for mixed vendor.
IMHO, it is easier to manage route summarization with EIGRP than area placement
with OSPF.

If I have:
2 Cores (6500's)
2 Distribution Routers (6500's)
10 Remote sites all connected via fiber to keep this question easier (4500's)
Where do I put my area 0? Core or Distro?
Do I configure all 10 sites as point to points? priority 0? or make either the
core or distro priority 255? (design wise whats best practice here)
