Hi. I can't see any big problems with a flat vpn-cloud considering the following: - The sites should ideally use a default route into the cloud. - The sites should have no requirement for segregation inside the cloud. - The sites should have absolutely common policies regarding all routing decisions and gateways in/out of the cloud.
Exactly what kind of distributed services are you thinking about?

If so, can you share any lessons learned from this service as opposed to building a hierarchal design (ordering multiple VRF clouds from a provider - core cloud, regional cloud, etc..). I'm in the process of identifying potential issues for a customer considering a flat network design model. Their network is currently regionalized with point-to-point circuits. Two of the first that came to mind were: - Summarization (could only do per site, no large regional summarization blocks). Unless defaults are used. - Difficult to deploy distributed services with no aggregation sites. Thanks, Dave _________________________________________________________________ The i'm Talkaton.
