WAN Design

[RS19]

I have my requirement as below.
There are 6 locations which needs to be connected over WAN.

Location-1 : IT Office (3 Floors)
Floor 1 : Company A
Floor 2 : Company B
Floor 3 : Company C

Each company needs to be logically separated. They may have same IP Segment or different IP Segment.
Each floor will have its own individual Acess layer switches & distribution layer switches.
But the Core switch will be common among for all these floors.
The should be segregation using VRF.

Location- 2 : Company A DC-1
Location- 3 : Company A DC-2
Location- 4 : Company A Head Office
Location- 5 : Company B DC
Location- 6 : Company C DC

All these needs to be interconnected using latest WAN technology.
I am not looking for SD-WAN (due to some reasons)

What are the other latest WAN technologies which can be used for interconnecting all these locations with proper segregation between different companies.

Options likes MPLS or hosting WAN providers etc would like to explore.
Pls provide me with the best design options (No SD-WAN)

Hi,

check MPLS over FLEXVPN if Cisco based solution you look for.

Any other solution like some service provider providing DC Hub kind of solution where we can terminate in common DC hub instead of managing our own DC for all DC interconnect.

MPLS over DMVPN I think the best solution here
