I need to migrate a traffic path which is going through Fortinet firewall device right now.
Once the migration is done, Data Center network(192.168.1.0, 192.168.9.0) will pass Meraki straight without Fortinet Fortigate firewall.
To test the migration, I am going to connect a cable between Meraki and the Core Switch and pass only a few specific routes (ex 192.168.13.0/24, 10.13.10.0/24). Other subnets will be passed by 192.168.0.0/16.
Once the migration is done, I will remove a cable between Meraki and Foritgate
If I connect Meraki and Core Switch will it create a L2 loop?
