My question pertains to active active or active passive firewalls and or servers.
Take for example a Cisco router. Each physical interface is programed with a unique IP address. That physical interface may have subinterfaces, however those subinterfaces are a seperate network. You can not program the same IP address on two interfaces.
Now take for example an HPE Aruba 5412 ZL2 with routing. You can program the VLAN in the switch and tag/ untag ports to that VLAN as you like.
From a cisco standpoint you would have to use a layer 2 switch in between the router and firewalls.
My questions are: If you have a firewall cluster (both firewalls have same IP address) can you plug those firewalls into an HPE switch configured wtih routing or would that be problematic?
Another example would be you have 2 servers configured as a failover, both servers use the same IP address.
Could those be plugged into an HPE 5412 ZL2 confifured with routing?
