-4 Remote offices
-3 have dedicated Internet
-1 Main Office
-Offices fully meshed through Frame-Relay
-Has dedicated INet
-2 Remote Data Centers
-Data Centers fully meshed with Main office
We're Configuring OSPF for our 4 remote and Main offices using Frame-Relay to fully mesh all locations.
Our main office also has a fully meshed point-to-point network with our 2 data centers.
We'll have 4 connections to the internet from our 5 offices and we'd like to be able to provide (originate 0/0) internet access to all offices (current and new) as a backup for those that have dedicated Inet and primary for offices w/o dedicated Inet.
All offices need to communicate directly with each other over the WAN.
We're currently using Static routes, but want to move to dynamic routing for resiliency and ease of scalability. We chose OSPF because it's compatible with our Cisco and non-Cisco equipment.
What's the best way to design the OSPF Areas that will give us the most effective routing and resiliency to failures while still maintaining a simple configuration?
