Self IPs

Hi All,

Do the Self IPs needs to be in same subnet for config sync to work? I have 2 Load Balancers 1 in China (physical box) and other 1 in Oregon (VM). I am trying to establish active/standby configuration between the 2. But I have L3/L2 challenges.

Thanks and regards, Ayush

I dont think it is required to be in the same subnet, configuration sync requires time on both devices to be sync. here is a link that helps troubleshooting configuration sync issues https://support.f5.com/csp/article/K13946.

Hi Kevin, thanks for the response.

  1. Currently the 2 boxes have discovered each other while forming Device Trust using the management IPs.

  2. Physical 'A' box is Online(Active) and we have kept VM 'B' box in Forced offline state. Both boxes show 'Dsiconnected'.

My physical box is on hardware 1600 and VM is on 7200 hardware. I see different Licenses for the 2 boxes, could this be the reason?

HI Please refer to the below link it will answer a few of your questions, before any configuration sync can happen the time on the devices needs to match.
