NimbostratusVIP control across data centers - how to ensure only 1 VIP is up at a time?
Hi -- at a very high level, we have a need for two VIPs (one in each data center), with automated orchestration so that only 1 VIP is up at a time. In more detail, we are setting up VIPs to proxy sy...
Hi daboocmeister3,
In DC2:
A new pool is used to monitor the virtual server in DC1. (A specific UDP monitor may be required.)
The number of active members in the pool is checked using an iRule, and if DC1 is up, incoming traffic is rejected.
when CLIENT_ACCEPTED {
if { [active_members /Common/pool_syslog_dc1_vip] == 1 } {
reject
}
}When DC1 VS is down, it is necessary to thoroughly test whether the monitor is functioning properly.
Another option instead of using iRule on DC2:
By using an external monitor, if the VS is up on DC1, the member is marked as down (reverse monitor). The syslog server on DC2 is monitored using a different monitor. Pool uses two monitors.
