ASA failover IP address

Wai Nam Mao — Mon, 11 Mar 2019 20:03:55 GMT

I have two ASA and want to form a active/stand by failover

Those ASA software version 8.3(1)

Can I just use the same IP address on all of the active and stand by interface?

The configuration for each interface needs to have something like this:

primary unit

int e0/0

nameif inside

ip add 10.10.10.1 255.255.255.0 standby 10.10.10.2

sec 100

When the primary and secondary unit sync they will have the same configuration in each interface.

You will get the following on the secondary unit

int e0/0

nameif inside

ip add 10.10.10.1 255.255.255.0 standby 10.10.10.2

sec 100

The important thing is to have the two units with the right failover configuration, on unit will be the active unit and the other the secondary unit.

I hope this helps.
