redundancy on core switch

Hi all,

We are going to implement redundancy at core level in which we will have two firewall and two switch in failover state as shown below

I will be using Sonic wall so we can configure high availability with one virtual ip.

I know the concept oh GLBP on switch for redundancy but I am not sure how to configure it and connect it with virtual IPs of firewall.

Please guide me regarding the configuration of this scenario.
