Question on how to properly configure a l3 port for HA.

I am doing HA on 1 L3 port, I am adding 2 addl L3 ports that will be setup for HA. SO i total it Will be 3 HA L3 ports.

1 port is already configured with this config below. Would hsrp be the best way to configure the ports. two of the ports are going to be connected to HA firewalls, and one port will be going to the ISR.

here is the config of the port going to the isr

• interface GigabitEthernet1/48
• description TO_ISR
