@Mohammed Thahif BK Thank you for reaching out to Microsoft Q&A.
I understand that you want to setup Azure Route Server with Cisco Meraki and PA Firewall. We do not have anything specific for Meraki+ARS+PA firewall setup at the moment. However, here is information on how ARS works with 2 NVA's in a Virtual Network which will give a generic idea regarding the setup. Hope this helps.
Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
