2 Stack L3 Switches with 2 Firewall in Active/Standby Mode

[foued kh]

Hi team,

I have to interconnect 2 sg550xg-24F in stack mode with 2 PA-220 in Active/Standby mode.

I choose this architecture :

I want to confirm with you if I must use VRRP in 2 switches and for the 2 Palo alto firewall should I need to use VRRP also or another protocol ?

Thank you in advance,

Any suggestions please
