HA A-P Cluster causing Loopback
Hi Guys and Gals,
Having some difficulty working out what best practices are for multiple switches in a HA A-P cluster.
At site 1 we have the following setup
At site 2 we have the following setup.
When I change site 1 to match site 2 we get a broadcast storm and another strange issue where the switch ports on the secondary fortigate start giving DHCP/internet access, needless to say things didnt work and we reverted to the original topology.
The only difference is STP is turned on in the hardware switch settings for the fortigate other than that everything else is the same. I've checked and I dont see a loop anywhere in the rack or on the floors. Why is this config that works at one site not working at another?
What is the best practice for an A-P cluster, if I have the switches connected like site 1 will clients connected to both switches retain network and internet access if the secondary fortigate takes over?
