Hi,

I am using neutron with ovn geneve. Currently I have two nic ports and I have bonded them in active passive bond in linux and assigned an IP address on vlan tagged interface for overlay network.

Is it possible that I can use two or more IP addresses for overlay tunnels between compute hosts ? I am planning to assign an IP on each NIC so that I can have redundancy as well as a pair of tunnel with more throughput between compute hosts ?

Hi Ammad, as per the ovn-controller code [1] it doesn't support list of IPs for the tunnel endpoints. Therefore you can't have 2 IPs used for the tunnels. If you want to achieve higher throughput you can configure the linux bond to use LACP and run it in active/active mode. I hope that helps.
