Subject: [Rdo-list] HA setup in Kilo
 

Hi Experts.

 

I am trying bring up 2 instance on Kilo with Active-Backup configuration. I need to float the external net IP between 2 instances. IP should get assigned to instance which acts as active. Can you please suggest the best method?

 

Thanks

Ganesh
