In Standalone LB, like to implement Active / Standby facility between 2 servers

Hi.. We have only 1 standalone lb implemented of LTM module for HTTP traffic.and we have only 2 servers.one is active and another is standby. Our requirement is 1.We would like to implement Active / Standby facility among the servers 2.The traffic shall always come to “Active” server 3.In case of “Active” server failure, the traffic shall be routed to “Standby” server 4.The user shall access the “Virtual IP” only and in turn LB shall derive the physical IP to route the traffic

 

How we are going to implement this in LB? please suggest different method to implement in LB.

    You can use Priority Group Activation on your pool to achieve this

     

    https://support.f5.com/csp/article/K7065

     

    Using pool member priority groups

    Use pool member priority groups to configure a pool with an alternate server or group of servers using a lower priority value than the primary server's priority values.

     

    Set the Priority Group Activation setting to Less than..., and then type the number of members below which the system activates the group.When the number of available members in the highest priority group drops below the minimum number, the BIG-IP system distributes traffic to the next higher priority group.

     

    Note: When the BIG-IP system activates a lower priority group and its pool members are processing connections, active and persisted connections continue to use the lower priority group pool members after a higher priority group becomes available. Connections to the lower priority group pool members continue until the connection has completed or the configured persistence timeout is reached.
