Does Neutron server node have fip namespace?

Hello,

I have 4 node Kilo installation with DVR and OVS. When I assign floating IP to VMs, fip namespace gets created on the compute host where VM is hosted. This consistently happens on all compute nodes as expected, except to the one with neutron server (network node). That host does have snat namespace, but not fip namespace. Is this expected?

The reason I am interested is that VMs hosted in the network node do not have working floating IP. VM successfully gets FIP assigned, but the VM is not reachable (ping, ssh) via floating IP. I do have security group rules setup properly. VMs on other nodes with the same security group are ping/ssh'able. I'd like to know if absence of fip namespace on the networking node is a root cause, or is it expected networking node to have only snat namespace, but not fip namespace.

Thanks,
