Does SD-WAN can solve ip adresses duplication?

[Hele Du]

Hi Experts,

Our company have about 20 branch office around the city.  They may have some duplicate addresses because of indivdually management.

We would like to deploy cisco SD-WAN solution for our branch and HQ.

Does the SD-WAN solution can solve this  or I must use a separate device to run a NAT service ?

I’m assuming today you have 2 separate networks that are integrated with a NAT enabled FW or router?

With Cisco  SD-WAN you could have a single cloud fabric and assign a different VRFs to each business or IP administration domain, if you need to share common services then you will need to NAT. This could be done at the DC (hub) these VRFs would be extended to your NAT device which would also provide connectivity between the VRFs. The below link goes into detail on segmentation which may be helpful.

Hope this helps.
