Configure OSPF with Extreme EXOS - Area Zero

Here is the outline for how to get OSPF running on 3 Extreme routers and then connecting them to a Cisco router to simulate an outside connection.

Things to keep in mind

• Your Router that will be connecting your the WAN/Internet needs to have "OSPF export"  to route the other interfaces in your ospf domain.  I am doing this with a static route in "Extreme 1"
• If you have interfaces on a local router you will advertise them by exporting them as "direct" routes.
• All routers need to be in the same area.  Area 0.0.0.0 is the default.
• Every router needs to have a different RouterID.
• Vlan 999 is my link out to the WAN.
