Public bug reported:

Hi,

I'm running Ussuri on Ubuntu 18.04 through Kolla-Ansible.
For network I use OVN.

Currently, if I create an instance with Floating IP and another Instance with Direct External IP (same network for floating IP and Direct External IP and same Subnet) :
-Instance with Floating IP can access to internal network and access to external network but can't access to Instance with Direct External IP
-Instance with Direct External IP can access to External network but can't access to Instance with Floating IP through his Floating IP.
-Physical server in "External Network" can access to Instance with Floating IP through his floating IP and can access to Instance with Direct External IP.

Network is VLan Type.


Step-by-Step reproduce :
-Create External and Shared Network (Vlan Type)
-Create Internal Network
-Create Router for Internal Network and use External/Shared Network as gateway
-Create instance in Internal Network
-Add Floating IP to this Instance
-Create instance in External/Shared Network
-Try to ping between 2 instances

Expected output :
-instances can ping each other

Actual output :
-Instances can't ping each other

Version : 
-Ussuri Stable
-Host Ubuntu 18.04 and container (kolla-ansible) Ubuntu 18.04
-Kolla-ansible deployment
