Hi Folks, Using Open vSwitch I am setting up VXLAN tunnels between hosts. I intend to make VXLAN tunnels "highly available" via Keepalived. Specifically, there are one master node and one backup node for each host, and they share a Virtual IP (VIP) via Keepalived, and the VXLAN tunnel will use the VIP as endpoint IP. This way when the master node fails, the backup node will automatically have the VIP shifted to it. Therefore, human efforts are not involved in failure recovery.
I thought VXLAN can work with VIP this way, since VXLAN simply uses UDP packets, and as long as the endpoint VIP does not change, it should work. But it turns out that it didn't at all. I wonder whether this is intended behavior or I missed something. (Please let me know if the problem description is not clear) Thanks! Changbin
