Hello Richard thank you for your reply. I was actually considering converting the Remote Location WAN router/switch to be the ABR, my only concern about that would be that, statistically, the point where a failure could occur is the WAN circuit and I would prefer that to be within that area. I understand that if i was to choose the option to go for a single-area design, that would require a recalculation anyway. Yesterday I was able to verify that our Carrier supports VLAN tagging so I used them to configure point to point links between all locations. That would be a quick and easy win for the first phase of our project (migrate from point-to-point WAN links to VPLS) that also gives us a very quick roll-back if there is a need. The second phase would be to migrate the remaining point-to-point circuits to a second VPLS cloud (from a different provider). In that case I guess i could do the same (VLAN tagging - if supported from the other provider), or convert the whole topology to a single-area design.

Hello, We have 3 remote locations connected to our HQ via 2 Point-to-point circuits from the same Carrier/Provider for each location. From an OSPF perspective, each site is a different area with the 2 HQ WAN Routers playing the role of ABR. At the HQ, we use 2x3850s for WAN routers (not stacked - they are physically located in different Data-Centers). For the remote locations, we use 2x3850 stacked (circuits are connected to different switches) doing both WAN routing and local Inter-VLAN routing. We don't have more than 1000 prefixes on the network and our network is fairly stable (failures that would affect routing and would require routing re-convergence do not happen often). The plan is to phase out one point-to-point circuit per location and replace it with a circuit to a VPLS cloud from another provider. So the question that arises here is, how should I configure OSPF? The VPLS cloud obviously is one big broadcast domain (one subnet) where all the Routers (1 HQ and 3 for the remote locations) are connected so I am not sure if multi-area OSPF is an option. 1. would you get rid of the other areas and migrate to a single area design? 2. if the carrier supports VLAN tagging, would you use that to configure subinterfaces, make the VPLS cloud a hub-and-spoke topology and keep the multi-area design the same? I have attached a 2 pictures depicting our current and future state topology. thank you

I have the same question. We are moving from 4.3 version to 4.4 (the latest). Does the same thing apply for this upgrade too?
We have about 2500 users that do not have admin rights and as far as I know since we do not have SCCM deployed yet, our only other option (if admin rights are required for the upgrade) is to do it using GPO from AD.
