two Data Center and one office
all interconnected with dual links (internally)
and one ISP at the Data Centers only. Office's ISP access goes through DC1's ISP.
What'd you recommend as far as OSPF design?
Should I have a single area zero ? We do not have many routers(routes)
Should have two areas: area0 internally and area1 for the public address(edge layer) or vice versa ??
I do want to have Internet failover between the Data Centers
And internally OPSF failover configured on the dual links.
