HA on the same device

[c-mu]

Hi!

I have several free SFP+ ports on my hardware. My goal is to secure my public IPs over two lines to the ISP Switch. However, an IP alias can only be assigned to one interface. How could I achieve this goal without using two Firewalls with CARP?
Thank you :-)

You could use a layer 2 protocol like LACP.

I was overthinking it. The simplest solution will indeed be to create a LAGG interface for failover or load balancing. Thank you!
