Neutron node flooding the network

I have a neutron openstack juno setup comprising of 3 nodes 1. controller 2. network 3. compute

All these nodes are connected to the public ip as against mentioned in the installation procedure. The network and the compute node are connected using a private network for tunnel mgmt. In order to provide public floating address of the same public subnet to the VM, an unnumbered interface is also created in the network node.

Once the VM is up and the floating IP is assigned, the whole public subnet goes down due to network node flooding the public subnet.

Any pointers on how to debug this issue?

Hi Samanta,

What type of traffic is flooded by the VM ? As a first step, I would block everything from this VM (IP rule deny) using Neutron firewall (just to make sure, the issue you have is related to this VM)
