Hi Arsen,

Could you provide more details about your environment ?

What I see from your link is, you use Neutron with Juno.

Are you using physical or virtual nodes ?

And, I guess you are trying to ping your router internal interface from Cirros ? Is this right ?

I guess you made sure everything was created on Neutron (subnet, router).

As a first troubleshooting step, I would suggest to capture from the instance interface (ovs-vsctl show and ip addr looking for the MAC of your vNIC) to the Neutron network node (traffic encapsulated using GRE - interfaces in the installation guide).
