2. Active – Standby
The only difference in case of a active-standby configuration is – the interface configured as standby is not used to send any out bound traffic. Thus disabling the load balancing feature of an active-active configuration.
Groupname: ipmp0
Active interface(s): e1000g0
Standby interface(s): e1000g1
Data IP addresse(s): 192.168.1.2
Test IP addresse(s): 192.168.1.3
