Bootstrap ASA failover configuration

Bootstrap ASA failover configuration

Here the configuration I use for ASA failover 8.4+ based on my experience:

On the primary:

interface GigabitEthernet0/4 no shutdown failover failover lan unit primary failover lan interface FAILINK GigabitEthernet0/4 failover interface ip FAILINK 169.254.255.249 255.255.255.252 standby 169.254.255.250 failover key 222Th3Hak3Y222 failover link FAILINK GigabitEthernet0/4 prompt hostname state priority

On the secondary:

interface GigabitEthernet0/4 no shutdown failover lan unit secondary failover lan interface FAILINK GigabitEthernet0/4 failover interface ip FAILINK 169.254.255.249 255.255.255.252 standby 169.254.255.250 failover key 222Th3Hak3Y222 failover link FAILINK GigabitEthernet0/4 failover

To validate:

show failover
