Use Case: Configure Active/Active HA with Floating IP Addresses
In this Layer 3 interface example, the HA
firewalls connect to switches and use floating IP addresses to handle
link or firewall failures. The end hosts are each configured with
a gateway, which is the floating IP address of one of the HA firewalls.
See Floating IP Address and Virtual MAC Address.
configure the virtual IP address to be a floating IP address.
Configure the floating IP address.
Do not select
Floating IP bound
to the Active-Primary device
Device 0 Priority
, enter a priority for the firewall configured
with Device ID 0 and Device ID 1, respectively. The relative priorities
determine which peer owns the floating IP address you just configured
(range is 0-255). The firewall with the lowest priority value (highest priority)
owns the floating IP address.
Failover address if link state is
to cause the firewall to use the failover address
when the link state on the interface is down.
