Systems, which are fully synchronized with their active peers, change immediately to the active state and
preserve active connections. At the same time, the backup Virtual Systems switch to standby, and
synchronize fully with the newly active Virtual Systems.
In this scenario, Member 1 fails and its active and standby Virtual Systems fail over to Members 2 and 3.
The active Virtual System (VS1) moves to Member 2 and directs all VS 1 traffic itself. Its backup peer on
Member 3 synchronizes with the new active Virtual System and becomes the standby.
VS2 on Member 2 becomes the standby and synchronizes with the active peer on Member 3. For VS3, the
active and standby peers remain the same.
Virtual System Failure Scenario
The below figure illustrates failure scenario where an active Virtual System fails on one member, but the
standby and backup Virtual Systems remain up. In this case, the active Virtual System fails over to its
standby peer (in this case on Member 2) and its backup (on member 3) becomes the standby, synchronizing
with the new active member.
Figure 5-25 Virtual System failover
All other virtual systems continue to function normally and no failover occurs.
