Failover solution for two ISPs

Hi,

I'm trying to figure out the best solution here. We have two ISPs providing Inet services for our org. One is to the the Primary line and the other is our secondary line. We would like to connect both lines to pair of Fortinet Firewalls (HA config). We have an option to configure the Fortinet's in either Active/Passive or Active/Active. They are currently setup in an Active/Active config. Each Fortinet (models: Fortinet 200D) has two WAN ports (WAN1 and WAN2). I have a number of servers that will be Inet facing (each with with Public IP assigned by my Primary ISPs IP block). My secondary ISP also has assigned up a block of external IP addresses as well. My question is during a failover scenario how does the failover happen exactly for the external IPs? I'm assuming DNS needs to be updated externally, but wondering how to configure it so that it happens automagically... hope this makes sense and appreciate any feedback from community!

Thanks
Rechi

The best way is to use BGP but two ISP has to agree with the configuration.

Thanks so much infamus. Really appreciate your feedback. Are you able to clarify the steps or config the two ISPs have to agree to exactly? I'm trying to figure out a solution that is the easiest to implement.

You will need to call back up ISP and tell them you need a failover solution.

There are different ways of configuring failover and they should have their preference.
